  • Canon MG8150 - unable to scan document to PC via wireless router, but works via USB connection?

    - by Heidi
    Please help. Get error that scanner disconnected or locked "code:5,146,555" when I try to scan a document to PC or attach to an email. Can't remember this function ever working and I've had this MFD for 2-3 years now. Printer function works fine via wireless, but not scanning. Upgraded my laptop a few months ago from Windows 98 to Windows Vista and reinstalled my printer/scanner software and drivers. Any ideas?

  • How can I set my TP-Link TL-WR1043ND to extend my router - modem range?

    - by Pitto
    I'd like to extend my WiFi coverage, so I've bought the TP-Link TL-WR1043ND and updated its firmware to the latest (wr1043nv1_en_3_13_4_up(110429)) but I can't find how to use its WDS function. Reading further on Super User I understand that both the modem-router (Pirelli Alice Gate) and the TL-WR1043ND should support WDS. Are there any tricks to achieve the same result - extending my WiFi range - even changing the firmware to DD-WRT or Tomato etc?

  • Why does pinging a local router return "Destination Host Unreachable"?

    - by Matt H
    I have two tomato routers. One is bridged wirelessly with the other. I have a new server on the network. It's running Ubuntu Server 11.04. They are all connected like this: A - Linux PC B - New Server C - Mac Mini D - Macbook T1 - Tomato 1 T2 - Tomato 2 They are connected like so: A -----+-T1 ==== wireless bridge ==== T2----- ADSL modem | | C & D Connected wirelessly to T2 B -----+ A, C & D do not experience any issues. I have an active SSH session to B from A and it's not experiencing any loss. B, the new server occasionally cannot ping T2 and therefore cannot connect to the internet. However, A can always contact B and B can ping A and B When the network is lost, B can still ping T1, but not T2 yet at the same as B has lost connection to T2, A can still ping T2. Any ideas on what this could be? there is nothing that gives any clues in any of the logs on either router or the linux server. One thing that is interesting is that I set up a ping running between B and T2. T2 has the IP address 192.68.1.1 Here is what I am seeing: From 192.168.1.1 icmp_seq=26 Destination Host Unreachable From 192.168.1.1 icmp_seq=27 Destination Host Unreachable From 192.168.1.1 icmp_seq=28 Destination Host Unreachable From 192.168.1.1 icmp_seq=29 Destination Host Unreachable From 192.168.1.1 icmp_seq=30 Destination Host Unreachable From 192.168.1.1 icmp_seq=31 Destination Host Unreachable From 192.168.1.1 icmp_seq=33 Destination Host Unreachable From 192.168.1.1 icmp_seq=34 Destination Host Unreachable From 192.168.1.1 icmp_seq=35 Destination Host Unreachable 64 bytes from 192.168.1.1: icmp_req=36 ttl=63 time=3.40 ms 64 bytes from 192.168.1.1: icmp_req=37 ttl=63 time=5.70 ms 64 bytes from 192.168.1.1: icmp_req=38 ttl=63 time=2.25 ms 64 bytes from 192.168.1.1: icmp_req=39 ttl=63 time=2.18 ms 64 bytes from 192.168.1.1: icmp_req=40 ttl=63 time=3.12 ms 64 bytes from 192.168.1.1: icmp_req=41 ttl=63 time=2.15 ms 64 bytes from 192.168.1.1: icmp_req=42 ttl=63 time=1.97 ms 64 bytes from 192.168.1.1: icmp_req=43 ttl=63 time= And it cycles to being reachable and not. So I guess you could say the question is, why is the router responding that it cannot be reached?

  • How do I make a TCP server work behind a router (NAT) without any redirection configuration needed.

    - by Chetane
    The scenario is the following. I have two machines A and B: A: Client (behind NAT) B: Server (behind NAT) I want B to be able to listen on any given port, so that A can send packets to B through that specific TCP port and receive any response. If both machines are not behind a NAT it is pretty straight foward process. However how do I make it work so that it works even when B is behind a router, without him having to go change the router configuration enable some port forwarding etc... For example, how do p2p program like torrent clients work without the user having anything to configure? Thanks and I hope my question is clear enough.

  • How to find the static ip address of my router?

    - by OSX NINJA
    I bricked my Linksys WRT54GS router when trying to change the firmware on it from dd-wrt to open-wrt. In order to unbrick it, I need to be able to do an ftp transfer to it. The problem is that it isn't using DHCP addressing and I can't just use the default ip address of 192.168.1.1. I have to use the ip address it was set at before it got bricked. The problem is I forgot what that number was. Is there some program or script that can find it out?

  • Linux how to force an external ping from eth0 to eth1 without a router.

    - by Elie
    Hello, i am trying to have eth0 connected to eth1 on the same machine with a loopback cable. I have eth0 as 2.2.2.1 and eth1 as 2.2.2.2 with netmask 255.255.255.0 and the right Bcast 2.2.2.255 . I tried to ping -I eth0 2.2.2.2 and ping -I eth1 2.2.2.1. My issue is that even when the loopback cable is not plugged the ping still succeed( as if it is an internal ping). How can I force an external ping where I make sure the packets are going through the connected cable? ( I know I can have a router and both ethernets connected to it, but I am avoiding to use anything besides a simple cat 5 cable). Thanks.

  • how to? 1 domain name, 1 ISP Static IP, 1 router, 3 physical web Servers

    - by buliwyf
    I have 1 Static IP from my ISP, 58.59.60.61 I have 3 local physical web servers: Win2008 IIS 7, local IP 192.168.10.11, mydomain.com Ubuntu Apache2, local IP 192.168.10.12, subdomain1.mydomain.com Win2003 IIS 6, local IP 192.168.10.13, subdomain2.mydomain.com I have 1 domain name, mydomain.com. It is configured this way: Host(A), @, 58.59.60.61 Host(A), subdomain1, 58.59.60.61 Host(A), subdomain2, 58.59.60.61 My router is a pfSense box. It forwards all port 80 traffic to a group alias called "WebServers," which is my 3 web server IP's. This setup should work right? I believe I need to set the "host header names" in my web servers. In IIS I know how to do this. How do I do this in Apache2?

  • How to ssh to my dorm computer with shared public IP and no admin rights over the router?

    - by Aamir
    First of all, I am not a Linux or ssh newbie. I have searched for this problem on many forums extensively but nobody seemed to have discussed this. Please help me! I live in a student dorm (off-campus) and all students of the dorm share the same WAN IP (Internet or public IP), which is fortunately static. I am not an admin and have no control over the router that assigns private IP's to all of the students, so I can't really forward port 22 to my computer :( Is it still possible to establish an ssh connection to my dorm computer from a computer on campus?

  • if an outdated, vulnerable but clean Windows machine is connected to network behind router, can it be detected and attacked?

    - by EndangeringSpecies
    suppose the machine is clean of all malware but not in any sense updated, patched, secured etc. Suppose I connect it to the internet from behind wireless router with the intent of using it only on a few trusted sites and only there. Or, for the sake of argument, maybe I wouldn't do any browsing at all, just let it sit there connected to the network. This is all happening in a residential situation with cable internet. In this situation can a remote attacker somehow detect the fact that the machine is connected to the internet and try connecting to do an exploit?

  • Cisco IOS router config -- how to disable SSH / SNMP on all but loopback address?

    - by chris
    Sorry for the naive question; a quick reading of the cisco docs doesn't answer this question... So I've got a router (say for the sake of argument a 4500 running IOS 15.x) It has interfaces in 3 different subnets -- 10.0.0.1/24, 10.0.1.1/24, and 10.0.2.1/24 It also has a loopback address of 172.16.0.33 How do I make it so that SSH / SNMP and other administrative traffic works on the 172 address but doesn't work on the IP addresses I wish to only use for L3 forwarding? Ideally this can be done by disabling the control plane access to these interfaces not just by using an ACL, but whatever, I don't actually care that much as long as it works... Thanks!

  • Laptop's wifi router is not emitting signals therefore my PC and Nokia cell are not connecting to internet

    - by umer sanny
    I have a USB internet connection which I plugged into my laptop. I converted my laptop's Wifi into a Wifi router so that I can attach my PC and cell to this network and enjoy internet, but it doesn't work. I have a Dell Inspiron N5110 i7 Windows 7 64-bit laptop, Dell D865 PC and Nokia C5. My PC and cell are showing that there is a new Wifi connection available, but when I connect to it, it won't load any web page. Reason is my laptop's Wifi is not emitting any internet signals or may be some other issue which i dont know.. laptop's adapter is 802.11b/g/n I don't know why. How can I enjoy Wifi internet on laptop, PC and cell at the same time?

  • Network? or router? problem

    - by Robert H Mercer
    I have two computers networked through a Netgear WG914 router which is connected to an Ipstar satellite modem via the RG47 LAN connector. The main computer is running Windows 7 Pro 64bit and the secondary computer is running Windows 7 Home Edition 32bit. On occasion there is a loss of internet connection usually on the main computer, often followed by a loss on the secondary comuter. Not, however, always the case. Windows troubleshooter, naturally, is about as much use as a politician in government.......NONE. There appears to be no problem with the ISP bad as it is and often the connection will be remade without any help from me. The difference in the OS's is not of any relevance since I had this problem before I changed over to Windows 7. Not being a nerd when it comes to networking I wonder if anyone has any constructive suggestions.

  • Can I replace a router and DHCP server without disrupting traffic?

    - by SRobertJames
    I have a device which acts as a router and DHCP server. I'm replacing it, and would like to minimize down time. If I unplug it, and plug in a different device with the same IP, will all the PCs with DHCP leases keep on working? (I have DHCP Conflict detect on, so it shouldn't reassign a DHCP address already used). What if I want to change the IP (new subnet) - is there anyway to tell all the clients (Windows PCs) to release their DHCP leases and request new ones in a minute? If before unplugging the old device, I have it release all DHCP leases, will the Windows PCs automatically ask for new DHCP addresses?

  • Sonicwall Global VPN Client fails to connect, despite successful connections from other computers from behind the same router

    - by JesperE
    I've recently been unable to connect to our Sonicwall VPN at work. The Sonicwall client is stuck on "connecting", and the log says "The peer is not responding to phase1 ISAKMP requests". The weird thing is that this is not an issue with my own PC, only my work laptop (Lenovo W530 running Windows 7 64-bit), and this has only appeared recently. This ought to rule out any problems with my ISP blocking VPN, or issues with the router itself. My company's IT department says that they cannot see anything in their logs when I'm trying to connect. My conclusion is that something is wrong on the laptop itself. Disabling the firewall does not help. Can the VPN connection be blocked in other ways? What should I be looking for? EDIT: This problem has "magically" disappeared, without any changes done in my network. I can only assume that this was caused by some network glitch with my ISP.

  • I believe I need a wireless access point, but can I do it with a wifi router?

    - by Flotsam N. Jetsam
    My needs are simple, I think: I have a laptop upstairs with a usb wifi that I use to connect to my neighbor's wifi which I share (with their knowledge). I have a laser printer downstairs that my wife doesn't wants to stay down there (big, bulky and ugly), but that we both need to print stuff off. It has wired networking and I have wired hub and router down there. The usb wifi on the laptop has absolutley the best reception I've ever seen or heard of. I cannot get onto the neighbor's net with the thing downstairs though--sortof in the ground. What do I need downstairs to give printer access to my laptop wirelessly? One thing I can't do in this solution is have a computer on downstairs, so I would think that would eliminate a usb solution.

  • Cisco 2900 series router - 3x 3g HWIC - Can you use the same subnet for each HWIC?

    - by Lance
    We host a site with a 2900 series router with 3x 3G-HWIC cards installed. It is hosted with telstra and plugs into our corporate WAN. The card authenticates against radius and advertises a route into the WAN for which subnet it routes for. We have always used the same advertised subnet on each. Telstra have advised us that this could be the cause of some drop out issues whereby some services will work for some people and not for others and are saying effectively that their system will only use one of these at a time even though we can see the interface is online and assigned a WAN IP address. Has anyone out there configured a multi HWIC setup before and if so are they using different subnets for each or the same?

  • Possible? OpenVPN server requiring both certificate- AND password-based login (via Tomato router firmware)

    - by Eric
    I've been using Shibby's build of Tomato (64k NVRAM version) on my Asus N66U router in order to run an OpenVPN server. I'm curious whether it's possible to setup this OpenVPN server to require both a certificate AND a username/password before a user is allowed access. I noticed there's a "challenge password" entry when filling out the certificate details, but everyone says to leave it blank "or else"; I have no idea why, and I can't find an explanation. In addition, I've Google'd this issue a bunch and have noticed people talking about a PAM module for OpenVPN in order to authenticate via username/password, but that appeared to be an either/or option; in other words, I can force authentication via username/password OR certificate. I want to require both. Is this possible? If so, how?
