  • Optimizing wireless router speed and minimizing interference.

    - by Tchalvak
    I've been experiencing problems with my wireless connectivity lately, and want to make sure that it's not related to the abundance of other wireless routers here in my building. So, what I'm looking for is a method (probably via some application or another) to audit the wireless channels (and other factors that might be important that I don't even know of yet) that are floating through the aether around me. Ubuntu or other linux apps are preferred, but some kind of windows/mac solution is possible, since I do have other OSes around me that I could install & test on. Router: netgear WGT624 v3 Hearsay tells me that channels 1, 6, and 11 are "non-overlapping" (I expect they aren't used for non-wireless-router purposes or something, not sure how they couldn't overlap with other routers using other channels), so perhaps my best choices of channel are limited, so if channels aren't really a big concern, I'd be happy to get links to other optimizations that I should look into.

  • Linksys WRT54GS V6 Router Blinking Power Light

    - by Frank
    I have a Linksys WRT54GS V6 Router in my possession got it at my local goodwill for 5$. Upon start up the Power LED starts flashing like crazy and at the same time the Ethernet ports all light up once then turn off (DMZ and WLAN never turn on). I can ping the router only by setting a static IP on my Pc. I can also successfully push a file (official Linksys OS and DD-wrt) into it via TFTP but this currently does nothing (no 192.1681.1 Access). Any ideas as to what may be wrong? I think its pretty obvious that it's bricked but.. I keep hearing a whole lot of "if it pings it's fixable" on the internet.

  • Dual-WAN router

    - by aix
    I am looking for a router that would fit the following requirements: Two WAN interfaces: the primary is PPPoE, the secondary will link to a GigE port on another router (a 100Mbps link will suffice); Two (ideally four) GigE LAN ports; No requirement for a firewall; No requirement for Wi-Fi; Inexpensive. The plan for the two WAN interfaces is as follows. All outbound traffic will go to the primary, with exceptions based on destination IP/subnet or possibly on src+dest IPs/subnets. Such exceptions should be routed to the secondary. It would be very nice if, should the primary go down, the secondary would automatically take over for all outbound traffic. I am reasonably sure that I can put something together based on dd-wrt. However, I'd like to hear from you what alternatives are out there (especially something easier to set up for my use case, even if it means paying more for the hardware.)

  • "DNS not responding" error with D-Link router and PPTP internet connection

    - by Born2win
    I have a D-Link DIR-615 router since around six months. My internet connection is VPN (PPTP) based, i.e. I have been given a username and password from my ISP and my IP address is dynamic. Since a few days I am experiencing a serious problem. My router connects normally (I can see the yellow light), but my computer is giving me a "DNS not responding" error. I have tried everything (reset, reboot etc.) but no success.

  • Using wifi router as bridge to increase signal?

    - by overtherainbow
    A friend of mine lives in an appartment building whose structure is such that wifi signal is very weak. Even a USB key won't work. I was thinking of buying an entry-level wifi router and reconfigure it as a bridge to act as repeater. Would that increase the chance of getting a good signal, or I shouldn't bother? If experience shows that it does improve things significantly, is their another router I should look at besides the Linux-based Linksys models? Thank you.

  • Very slow loading pages with router

    - by user984621
    I bought new router - this one: http://www.tp-link.com/en/products/details/?model=TL-WR841ND and the problem is, that the loading pages is so slow, even sometimes the pages aren't loaded at all. Is the same, when I have on the Mac OS or Windows. Below are the informations from the router-admin section: LAN IP Address: 192.168.2.1 Subnet Mask: 255.255.255.0 WAN IP Address: 192.168.1.100 Dynamic IP Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.254 DNS Server: 89.203.178.2 , 10.14.2.1 How can I fix this problem? Is almost impossible to use the internet this way.

  • unable to connect to remote sql server from SHDSL router

    - by user529265
    Got a new leased line network to our office that came with a SHDSL router (Watson). Currently, we are unable to use Sql Server management studio to connect to remote Sql databases. It errors out saying A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (Microsoft SQL Server, Error: 64) I logged into the Watson management panel and unblocked all the ports for TCP traffic (specified the range as 0 to 60000 and UDP as well - this include 1443 required for connecting to SQL Server). The router is the only thing that has changed. We are able to connect to it from other networks just fine. Is there something we are missing here. Any help would be greatly appreciated.

  • How a router decides destination of packet?

    - by user58859
    I have basic networking question. Scenario : Two pc's are communicating on a wan. Both the pc's ate behind routers or modems. My question : Both the pc's have public IP of each other. That public IP is most of the time is either of the router or of the modem. There can be more then one pc's behind those routers and modems. Then how the pc's are communicating. I can understand the packets can reach upto those routers or modems. But what after that. In the packet , destination IP is public IP. Then how the router or modem decides where to send the packet? Can anybody explain me this please. Thanks in advance.

  • Sagem Router Wifi Key Issue

    - by user23392
    Hi I have a multiservices sagem router which supports wifi as well, the pack came up with a default wifi configuration key and a WEP Key in the label of the package like this: WIFI Configuration key: abcd1234 WEP Key: C4H2F167C10263AEB98V52920E Now, when i execute the wifi usb wizard in the official cd, it asks me for the WIFI key, i put the abcd1234 & it says it's incorrect, i try the long WEP key and it says that the key should only have 8 characters. When i go to the control panel of the router in the wifi config, i see that: Open Authentification System WEP 128 Bit Passphrase: C4H2F167C10263AEB98V52920E Now since the wizard only accepts 8 characters, i try to change the 128bit to 64bit and put some 8 characters and it ends up saying that the new key should be 5 or 13, or 10-26 hex numbers. What to do? Thanks

  • Suggest Cisco Router for a small company of 60-100 Users

    - by user69154
    Trying to find the right router to use - we'd like to go Cisco. We have ~60 programmers that do alot of remote server work. Will grow to 100 programmers by the end of the year. We've talked to companies that sell Cisco routers. While they make recommendations, we feel that the sales guys may be selling us an overkill solution. What kind of company (that is not linked to sales of routers) can provide a service to recommend the right kind of router for our company? There are lots of network engineers out there, but am looking for some company that focuses on advising a network solution. Any suggestions of companies are welcome.

  • Does Huawei E398 LTE Modem works with Netgear Router?

    - by Paul Smith
    I've been using a Netgear router sharing the signal through my Huawei E160 dongle, but following the speeds update and the device limit, it does not satisfy the demand. Through research, I've found that Huawei E398 is the latest and functional dongle so far. I'm going to update, but the confusion comes: Is it compatible for my Netgear router? Will it work? Any information will be appreciated. I found the unlocked E398 here.

  • Wi-Fi connection drops when downloading torrents, but wired connection still works

    - by bryan
    After downloading for an hour or so, the Wi-Fi connection on my tablet stops working; forcing me to restart my router(it basically hangs when trying to connect). This only happens when downloading torrents. WIRED connection on my desktop PC with router still works fine; no issues at all. I tired to lower the number of global connections to 50, but I still have the problem. I have also updated to the latest Linksys firmware. One PC, a tablet and a smartphone. I have COX cable. Please let me know if you need any other info. Thank you!

  • DNS Server address configured inside Router not working

    - by Charandeep Singh
    Well, I have an ISP router in which I have configured DNS Servers to use (Primary & Secondary) like Google DNS. It works just fine. But now I have setup a computer with DNS server (Simple DNS Plus). I got it working by settings my internal DNS Server IP Address in computer. i.e. 192.168.1.3 So, instead of settings my internal DNS IP Address in every computer in my network, I want to setup DNS Server into my router. So on every DHCP request, computer get DNS Server to use. So I configured it like this: Primary DNS: 192.168.1.3 Secondry DNS: (left blank) After applying and DNS Requests stop resolving. But strange part is DNS request does goes to DNS Server but maybe not returned back, because all DNS request were available in cache logs. I don't know why this is not working, let me know if you have any solution or wordaround for this. Thanks! Update 1: NSLOOKUP Result C:\Users\user>nslookup google.com DNS request timed out. timeout was 2 seconds. Server: UnKnown Address: 192.168.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to UnKnown timed-out

  • Make router forward HTTP and HTTPS traffic to external App

    - by cOsticla
    I use a Linksys WRT54GL router with DD-WRT v24-sp2 (10/10/09) std (SVN revision 13064) which I am trying to make forward all HTTP and HTTPS traffic to an external app called Fiddler (used as proxy) on port 8888. After a lot of digging on this site, dd-wrt forum, dd-wrt.com and WWW, I am stacked with the following piece of code that works (thanks to the guys from dd-wrt support for this info), but only for forwarding HTTP traffic (port 80): #!/bin/sh PROXY_IP=1234567890 PROXY_PORT=8888 LAN_IP=`nvram get lan_ipaddr` LAN_NET=$LAN_IP/`nvram get lan_netmask` iptables -t nat -A PREROUTING -i br0 -s $LAN_NET -d $LAN_NET -p tcp --dport 80 -j ACCEPT iptables -t nat -A PREROUTING -i br0 -s ! $PROXY_IP -p tcp --dport 80 -j DNAT --to $PROXY_IP:$PROXY_PORT iptables -t nat -I POSTROUTING -o br0 -s $LAN_NET -d $PROXY_IP -p tcp -j SNAT --to $LAN_IP iptables -I FORWARD -i br0 -o br0 -s $LAN_NET -d $PROXY_IP -p tcp --dport $PROXY_PORT -j ACCEPT I tried to edit the code from above and I came up with the following but it's still not forwarding HTTPS but just HTTP traffic: #!/bin/sh PROXY_IP=1234567890 PROXY_PORT=8888 LAN_IP=`nvram get lan_ipaddr` LAN_NET=$LAN_IP/`nvram get lan_netmask` iptables -t nat -A PREROUTING -i br0 -s $LAN_NET -d $LAN_NET -p tcp -m multiport --dports 80,443 -j ACCEPT iptables -t nat -A PREROUTING -i br0 -s ! $PROXY_IP -p tcp -m multiport --dports 80,443 -j DNAT --to $PROXY_IP:$PROXY_PORT iptables -t nat -I POSTROUTING -o br0 -s $LAN_NET -d $PROXY_IP -p tcp -j SNAT --to $LAN_IP iptables -I FORWARD -i br0 -o br0 -s $LAN_NET -d $PROXY_IP -p tcp --dport $PROXY_PORT -j ACCEPT I am not sure if is possible to forward HTTPS traffic anymore by just using a router so I'd appreciate if somebody will share his thoughts and/or examples regarding this subject here. Thanks!

  • Suspected Router problems, [closed]

    - by jordon_user
    I am new to this forum. I appreciate any help you can offer. I have been troubleshooting an error with both my WIRED Internet Connection I have 3 desktops running through this working connection (Router) with no problems. Two computers, one laptop and desktop experience the issue. If I connect directly to the Modem, on either, no problem on the internet. Through the Router, my computer connects for a period of time but if ever awaking my comp, or restarting, the yellow explanation mark returns. The only way I can get the connection up = cmd. ipconfig /release, ipconfig /renew. This constant command is annoying and was hoping for a permanent fix. Audio is also not working. I know its likely a driver error, but its an old comp we put together and if there's an easy fix itd be great to hear from you! If you need any more info just let me know. Thanks! THanks guys!

  • Opening port 80 in router has no results

    - by Ricardo Pieper
    A friend of mine has a ADSL modem and I need to forward some ports. I have already forwarded the 1521 port (Oracle) and it's working fine. Now I need to forward the port 80. I already set up his IIS bindings to this port, and also forwarded the port like this video shows: https://www.youtube.com/watch?v=DLKD-fyexoo So I think I did everything correctly. The local IP address is also the same as the machine where the IIS server is running. I'm sorry, but I can't post images since i don't have 10 points :( Somehow I can't forward this port, yougetsignal.com keeps saying that the door is closed. When I try to open the port, the Control Panel says me that I have to access the control panel in the 8080 port, because the 80 port will be open. Ok, that's fine. But I'm still able to access it in the 80 port, and when I try to access it in the 8080 port, it doesn't work. I'm trying it with the TPLINK 8816, but I also tried to open it in the Opticom DsLink 279, and it didn't worked (using another machine), I got the exact same results. He has a dynamic IP address, but he is also using No-ip, so I can always access his Oracle database in a certain static address. The 1521 port is open. I also tried to disable the firewall in Windows, but that makes no sense to me, since the router doesn't really open the port 80. Clearly I'm missing something. I have never done it in my life, so I dont know how to proceed. Restarting the router was the first I did, no results. I'm accessing his laptop through TeamViewer, so I'm testing the port outside his local network. Edit: My ISP says that they allow to open ports, and the 1521 port is opened. What could I do to open the 80 port?

  • Cisco router not receiving OSPF updates

    - by WebDevHobo
    Or at least, that's what I think is happening. There doesn't appear to be a debug command for this, or to see if something is in the routing table. I'm testing out this setup in Packet Tracer. I have 3 routers and a webserver From left to right, you have: Webserver - Router1 - Router2 - Router3 Router1 and Router2 can succesfully ping WebServer. Router3 cannot. Router2 has a default gateway set, to send all not-recognized data through its serial interface to Router1. Like this: ip route 0.0.0.0 0.0.0.0 Serial 0/0/1 Serial 0/0/1 being the connection to Router1 Router2 and Router3 have OSPF configured. From their "show run": Router2: router ospf 1 log-adjacency-changes passive-interface Serial0/0/1 network 10.1.1.0 0.0.0.3 area 0 default-information originate ! Router3: router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.3 area 0 passive-interface FastEthernet0/0 ! I was under the assumption that setting default-information originate on Router2 would give Router3 the needed information. What's going wrong here? The interfaces are up. Ip addresses are with mask-range, clock rate is set at correct end. I don't know what else to check.

  • Netgear Router missing Wireless Configuration Menu Link

    - by ccisystems
    I have a Netgear WiFi router DG834G v3. On it it says it's a WiFi, ADSL 2+ modem, switch, etc. There is an antenna on the back and a WiFi indicator on the front. However, when I connect to it via the web interface, the wireless setup link is missing from the menu. The top label indicates it is a DG834 (without G). I have received it from a friend and was really looking forward to using it but I really need the WiFi part. I looked on Netgear's site as I thought someone must have uploaded the wrong firmware for the device sometime - so I upgraded to the latest firmware, but it still says it's NOT a 'G' device and the wireless menu is nowhere to be found. I'd appreciate a push in the right direction as to what I could do. Is it possible that the WiFi chip is broken or something and the device does not detect it and the firmware reverts the device to a different version?

  • DD-WRT Acces Point as a Router

    - by Dzh
    Following suggestion to this question asked on Network Engineering, I am asking the question here. this is an extension to my previous question (I think it was deleted), where I was claiming that DDWRT was disabling it's DHCP server once connected to the network. I was wrong, as it now seems that it is bridging itself with another parallel connected wireless router. I have two Draytek 2820 and one Netgear WG602v3 with latest DDWRT. Lets call one wired-Draytek and it has wireless disabled. The other one, let's call it wireless-Draytek, is connected to wired-Draytek and has wireless with MAC filtering enabled. Once I connect Netgear to the wired-Draytek, the client that connects to Netgear, will be assigned with IP address from the wireless-Draytek. If the MAC address is not on the wireles-Draytek, the client is unable to obtain IP address and has no connectivity at all, even with manually assigned static IP configuration. To illustrate further, this is how network is set up: wired-Draytek ---------- wireless-Draytek \_________ Netgear What I wish to have, is that Netgear issues IP addresses from it's own IP pool and ignores the MAC filtering rules from wireless-Draytek. This is kind of puzzling how this they are bridging (if they are) themselves automatically. Thanks. UPDATE: It's not a home network. I gave you a bit simplified set-up. If there is a better site on Stack Exchange to ask this, please let me know. The Drayteks are running stock firmware, it's only Netgear that I've flashed to get more stability. In addition to these routers, I have also three 3COM Baseline switch 2824, and another Draytek router with Prosafe FS752TP PoE switch dedicated for VoIP phones. Wired-Draytek has IP 10.0.0.1, DHCP disabled as there is AD DC which is issuing IP addresses. Wireless-Draytek has IP 1.1.1.1 and DHCP enabled. Netgear has default - 192.168.1.1. As per suggestion, the specific question is - how do I isolate these two wireless routers?

  • Netgear router is not resolving hostnames

    - by Thomas Clayson
    Not sure what the problem is, but I am used to being able to access other clients on my LAN via their hostname. We got a new router from plusnet (Netgear WNR1000v3) and now this has stopped working. For instance, if I were to run a web server from one computer with the hostname TomPC usually I could go into a browser and type http://TomPC and I would get the web server front page. I can access it by using the LAN ip of the machine. e.g. http://192.168.1.1 works fine. I thought it would be a simple option in the admin panel of the router - possibly I had to turn on DNS/DCHP or something. But I can't see anything, and my searches on the internet seem to turn up ridiculous solutions involving setting up a dedicated DNS server on my LAN. This is just a small home network - really I just want to be able to access my Raspberry PI on the network without having to work out the IP address every time. (I know I could just set a static IP address for it, but using its hostname would be much easier). DCHP is enabled in the LAN settings part, although RIP is disabled (I don't know what the latter is) I don't know if this has anything to do with it? Many thanks!

  • Switch Before Firewall / Router - Multiple public IPs

    - by rii
    I currently Have a 10Mbit Full duplex circuit connected to a small unmanaged switch which then connects to a Sonicwall Firewall / Router. I have several public IP addresses (/28) that are assigned to several devices in my setup. Now the problem is the small switch I have was lent to me and needs to be returned, I have replaced this switch with several other switches but for some reason any other switch I use causes the network to become extremely slow. I believe this is a problem with the autonegotiation of theses hubs, so I am thinking of purchasing a small managed switch (cisco 300 series) and making the receiving port on the swith Explicitly 10Mbit Full Duplex and see if this works. My question is, being that this is a managed switch and needs an IP, will I still be able to run my public ips through it? Say the circuit has 70.80.4.1 - 7 will I still be able to assign 70.80.4.2 to my firewall and 70.80.4.3 to my router connected to some other port in the switch? Will I have to assign the switch a public IP address in this range as well for it to "route" to those other devices or does the switch does not care what IPs goes through it while operating as a Layer 2 Switch? Any help would be greatly appreciated. Thanks in advanced!
