  • Why can't a device connect through a wireless after router restart?

    - by Kalmar
    My laptop with lubuntu 12.04 used to connect to the wifi. But after the router (Cisco E4200) was restarted I cannot connect anymore through wireless connection. (No problem using a cable.) The network is hidden and secured by WPA/WPA2 Personal, I am the only person having this problem, so I guess it's somewhere on my side. What could cause such a problem, how to diagnose it and finally how to fix it?

  • Jerky transition after the login screen

    - by Bastien
    Hi, I have a clean install of Windows 7 Professional x64. After I type my password at the logon screen, the blue background is supposed to fade away smoothly and show the desktop, but on my machine the transition is jerky. I have an ATI graphics card and the Catalyst 10.2 drivers. What can I do to make the transition more smooth? Thanks!

  • Installing drivers for switchable graphics

    - by Anonymous
    I recently bought a laptop that came with Windows 7 64-bit installed. I have some older (16-bit and 32-bit) software that doesn't work with 64-bit Windows, but works just fine with 32-bit. Since I also wanted to get rid of all of the pre-installed spam, I decided to wipe the hard drive and install a fresh copy of Windows 7 32-bit. I can't get the graphics cards working. This laptop uses switchable graphics, an Intel card and a Radeon card. I first tried installing this driver from Intel, which works for the Intel card. Of course, the Radeon card doesn't work with this driver and I need it for some of the newer games I have. I also tried this driver. Windows's device manager will recognize the Radeon card, but it will still use the Intel card. Also, even though that package says it contains the Intel driver, the Intel card still isn't properly recognized by Windows (leaving me with a nasty 800x600 resolution). On top of that, the Catalyst Control Center won't open (saying "The Catalyst Control Center is not supported by the driver version of your enabled graphics adapter") I tried installing HP's driver then installing Intel's driver on top of it. Device manager will then recognize both graphics cards properly. However, the laptop still uses the Intel card. The CCC still won't start (saying the same thing as before) and I can't find any of 'switching' graphics cards. Before formatting, I could right-click the desktop and click "Configure Switchable Graphics" This option hasn't been in the context menu regardless of what driver(s) I've installed. After some research, I found out that this menu entry runs the command "cli.exe Start PowerXpressHybrid" I've tried manually running this command, but I get the same unsupported message from CCC. So, does anyone know how I can get this working? I would like to be able to switch between the Intel and Radeon. But, if there's some way to disable the Intel and use only the Radeon, that would be fine I dual-boot with Linux (framebuffer uses the Intel, haven't even tried getting X set up yet) Here's the output of lspci # lspci -v | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] (prog-if 00 [VGA controller]) The laptop is a HP Pavilion g6t-1d00. HP doesn't support installing anything but Windows 7 64-bit, so calling tech support isn't an option. Thanks for any help UPDATE: I finally got it working. After a fresh install of Windows 7, I installed the HP driver (the one linked above). Then, there's an optional Windows update I installed (don't remember the exact name, but it'll stick out). After that, graphics switching works just like it's supposed to. Moab, thanks anyways for your help

  • Running a 2048 x 1152 monitor on a Dell Vostro 220s with HD3450 video card

    - by Jon
    I recently bought a new monitor which has a resolution of 2048 x 1152. However, this resolution is not on in the options list. I have tried installing ATI Catalyst but to no avail. I am running the monitor on the VGA cable. How can I add the resolution to the settings drop down? Additional info: VGA is through a splitter cable from DVI The outputs on my grahics card are DVI and VGA Monitor only has VGA input

  • Ubuntu 10.04 LTS - Dual monitor works only sometimes (ATI multi-desktop)

    - by Beres Botond
    I've been using my laptop with an external LCD monitor attached to it at work (Philips 201E). And at home with a different external monitor (Samsung 2032BW). I have an ATI graphics card (HD3450), with Ati Catalyst drivers enabled and I'm using the Single display desktop (Multi-Desktop) seeting. At work I have the external monitor on the left and laptop on the right, while at home the other way around. So when I switch between the two setups, I just needed to go to Ati Catalyst Control Center, change the order of the displays, change the resolution (Home - 1680x1050, Work - 1440x900), reboot and it was all fine. But since a while it doesn't work properly anymore: At home it still works fine. At work it doesn't work. Sometimes it works for some reason, after a few resolution/setting changes in ACCC and reboots... it's very strange and annoying. With the home monitor I can see the whole bootup process on both monitors (laptop + LCD) and it always just works fine. With the work monitor on the external LCD monitor I just see "No video input" until I get to the login screen, then it shows up there as well. But after login it will either: Flicker a few times, but then work OK. Or (more often) Flicker once and then go back to "No video input" again. I usually end up rebooting a few times until it works. Does anyone have any idea for fixing it?

  • Kill overscan for ATI drivers?

    - by joeforker
    I have a dual-boot Windows 7 64 bit/Linux 64 bit machine that uses ATI's Catalyst drivers. Sometimes I attach it to a 1080p LCD TV over HDMI. ATI is daft enough to provide a border to account for overscan. I'm using an LCD TV. No overscan, or it looks like crap because the pixel mapping is not 1:1. How do I disable this driver "feature" in Windows? in Linux?

  • 1680x1050 via VGA won't work correctly in Windows 7 32bit

    - by Boldor
    I am trying to connect a Samsung 22" SyncMaster with my laptop running Windows 7 32-bit, an AMD HD 6500 Mobility. Though Catalyst Control Centre as well as Windows identify the correct resolution of 1650x1080, and it is selected, it isn't displayed. Looks more like a lower resolution that's getting stretched over the monitor. The weird part: The monitor worked for years without problems, one day it decided not to work properly anymore. Maybe some update issue, I have no idea.

  • Tool to Set a Hotkey to Adjust Overlay Surface Gamma

    - by Synetech inc.
    I am looking for a (Windows XP) utility (preferably a standalone app) that can let me set a hotkey to adjust the gamma (and hopefully other color settings) of the overlay surface. ATI Tray Tools does not have the ability to bind the overlay color adjustments to the overlay. I’ve asked him about it and he said it was difficult to implement or something (he was kind of vague). The ATI Catalyst drivers do not have a hotkey function for the overlay tab either. Can anyone help?

  • ICMP Redirect Theory VS. Application

    - by joeqwerty
    I'm trying to watch ICMP redirects in a lab using Cisco Packet Tracer (version 5.3.2) and I'm not seeing them, which leads me to believe that either my lab configuration isn't correct or my understanding of ICMP redirects isn't correct or that Packet Tracer doesn't support/use ICMP redirects. Here's what I believe to be true regarding ICMP redirects: Routers send ICMP redirects when all of these conditions are met: The interface on which the packet comes into the router is the same interface on which the packet gets routed out. The subnet or network of the source IP address is on the same subnet or network of the next-hop IP address of the routed packet. The datagram is not source-routed. The router kernel is configured to send redirects. I have the lab set up in Cisco Packet Tracer as displayed in the image and would expect to see an ICMP redirect from Router1 when pinging from PC1 to PC3. I'm not seeing the ICMP redirect and it looks like Router1 is actually routing all of the packets via Router2. I have IP ICMP debugging enabled on Router1 (and Router2) and I'm not seeing any ICMP redirect activity in either console. I'm also not seeing a route to the PC3 network in the routing table on PC1, which I think confirms that the ICMP redirect is not occurring. I'm using only static routing on Routers 1 and 2. Is my understanding of ICMP redirects incorrect, or is there a problem with my lab configuration or does Packet Tracer not support/use ICMP redirects?

  • Experiences with BIRD for BGP?

    - by Shtééf
    We're currently using Quagga with Debian Linux to run a full table BGP router. The set-up has been dead simple up to now, but we've come to a point where I have to reconfigure the router quite a bit, and want to tighten things up. I've never really understood Quagga, and always found its documentation to be lacking. It appears to be mimicking Cisco, of which I only have basic understanding. BIRD has caught my eye recently. The couple of articles / presentations I found promote it as lightweight and more responsive under stress compared to Quagga. And it actually seems to have very decent documentation. So I'd like to know: Who's running BIRD right now, and in what kind of set-up? How is it stability-wise? I've read about it running in a couple of sites in production. Let's say I don't care at all for a Cisco-feel to configuration. How is configuration, maintainance, monitoring, etc. of BIRD in general? And any other notable experiences you may have with it.

  • Modem doesn't seem to pass internet connection to router

    - by Vian Esterhuizen
    I was supplied a Cisco DPC3825 modem by my ISP and use a Cisco E4200 as my main router. Today the Internet just stopped working, just out of the blue, I can't think of anything that would have triggered it. It's been working pretty good for the past month except for a few random blips here and there. After some trouble shooting I realized that a direct wired connection to the modem would get me Internet access but if I was wired to the router as I was before I would have no connection. Assuming it was router I connected a TP-Link WR841N but it had the exact same problem. Also, connecting to the router via Wi-Fi from multiple devices will connect me to the router but I still can't get access to the Internet. From these test, it seems that the modem just won't send Internet through to the router but is clearly connecting and able to directly connect to my PC. What I've Tried A full reset and factory reset on the E4200 A full reset on the modem (but I believe my ISP has remote access to the modem because the passwords and so on are always set back). My ISP has remotely reconfigured the modem What I Should Try What else can I try? What should I do to try to narrow down the issue? Can you figure out what the problem might be based on this information?

  • Advice on networking career

    - by fmysky
    Hello! I need some insights on a networking career. I have a valid CCNA and few months of experience as a Jr. network analyst. My focus is a type of job where I can administer networking/storage hardware and possibly managing servers/workstations too. I am new to this job area, specifically new to city like LA. I am currently unemployed and so, my question is: should I continue with my cisco certifications(routing/wireless) or other comptia certs or both to get a reliable job? I am really interested in CCNA wireless but watching craigslist(LA) and other job sites, it seems people need more cisco voice people. While, some others also ask for Net+ certs. I have scarce financial sources so, its better to make some good decisions. I have not been applying yet due to some personal problems but I will soon. Thank you! P.S. I don't know if I can ask questions like this here. Sorry about that.

  • Citrix Access Gateway with Citrix Receiver

    - by vm370
    I'm currently using a Citrix Access Gateway with firmware 5.0.4 to provide access over an SSL-VPN to an isolated environment, which is connected to over the Citrix Access Gateway Client, which is delivered by the device by default. However we encountered different problems, e.g. that it's somehow not possible to get it out of the autostart (not registered as a service or in the autostart?!) and it killed the Cisco VPN Client, which is used in the company and unfortunately cannot be replaced. The Cisco client can also just be used again after a procedure with cleaning the registry from all CAG Client remains, which requires a lot of effort. Because of that, I'd like to check if there is an alternative to this client, since is this is a real pain... Unfortunately I couldn't find a way to use the Receiver with the CAG yet, but if you have any resources on how to build this workaround, I'd be very happy. Thanks a lot in advance UPDATE: If there are other alternatives I'd be even more happy, since using the Receiver would also mean that there is an issue with the ICA-Client, which is also used in our environments. From my experience, the Receiver and the ICA-Client are also no good friends...

  • HP Procurve Issue Passing Multiple VLANs over a link

    - by MichaelRwat
    Just to start off with I am a Cisco guy that got placed into an HP project. Basic topology overview from outside in: ASA 5505 with two Ethernet connections to a 2910-24 port switch. This switch is then (Cisco Trunking) to a 2626 switch passing vlan (1 untagged and 100 tagged)between them. I created SVI's on each of the switches for both VLAN's for testing purposes. I can not get vlan 100 to pass across this link. I also have trunks configured to AP's off of the switch and can not ping the vlan 100 BVI on the AP's but can reach the vlan 1 BVI. Port 25 on Access layer (2626) connects (trunks) with port A1 of 2610. STP is not running at all on any switch (this is not my network I can't change this nor did I design this) Distribution Sw: MP1-0# show run ip default-gateway 10.100.100.100 vlan 1 name "DATA" untagged 1-22,24-A1,B1 ip address 10.100.100.6 255.255.255.0 no untagged 23 exit vlan 100 name "GUEST" untagged 23 tagged 24-A1 ip address 10.100.102.6 255.255.255.0 exit Access Sw: ip default-gateway 10.100.100.100 vlan 1 name "DEFAULT_VLAN" untagged 1-26 ip address 10.100.100.5 255.255.255.0 exit vlan 100 name "GUEST" ip address 10.100.102.5 255.255.255.0 tagged 15,25 exitt From the ASA I can ping the vlan 100 address of the 2610 but not the 2626 (10.100.102.6)[Not passing the "trunk"] If I plug into an access port vlan 100 of the 2626 I can ping the SVI for vlan 100 as intended. I can not ping across the "trunk" over vlan 100 but I can across vlan 1. There may be something obvious I'm missing but please review my configuration and thank you for the assistance.

  • Public-to-Public IPSec tunnel: NAT confusion

    - by WuckaChucka
    I know this is possible -- and apparently fairly common with larger companies that don't/can't route private addresses for overlap reasons -- but I can't wrap my head around how to get this to work. I'm playing around with pfSense, Vyatta and a Cisco 5505 right now, hardware-wise. So here's my setup: WEST: Vyatta outside: 10.0.0.254/24 inside: 172.16.0.1/24 machine a: 172.16.0.200/24 EAST: Cisco 5505 outside: 10.0.0.210/24 inside: 192.168.10.1 machine b (webserver): 192.168.10.2 So what we're trying to do is this: route traffic across the tunnel from machine A to machine B without using private addresses. i.e. 172.16.0.200 makes a TCP request to 10.0.0.210:80, and as far as EAST is concerned, it sees a src IP of 10.0.0.254. On WEST, I have your typical many-to-one Source NAT to translate 172.16.0.0/24 to 10.0.0.254 and that's confirmed to be working. Also on WEST, I have the following IPSec config: Local IP: 10.0.0.254 Peer IP: 10.0.0.210 local subnet: 10.0.0.254/32 remote subnet: 10.0.0.210/32 I have the reversed configuration on EAST. What happens when I make a request from machine A to 10.0.0.210:80 is that the SNAT translates the private address of machine A to 10.0.0.254 and it's routed out (and discarded at the other end) without establishing the tunnel. What I'm assuming is happening is that the inside interface on WEST receives a packet from 172.16.0.200 and since this doesn't match the local subnet defined in the tunnel configuration, it's not processed by the IPSec engine and the tunnel is not established. How do you make this work? Seems like a chicken and egg thing with the NAT and IPSec and I just can't wrap my head around how this can be done: can I say, "if a packet is received on the inside interface with a destination of 10.0.0.210, translate it to 10.0.0.254 before the IPSec engine inspects it"?

  • Site to Site VPN problem, connection succesful data only oneway?

    - by Charles
    To start things off, I'm not the actual Administrator for the VPN Server, but he is also at a loss so I thought I'd ask it here. I know it's a Cisco ASA Firewall/VPN. I have a router that connects to the Cisco VPN server, it does so succesfully. I can ping everything within the remote network and from the remote network into my own. I've been able to SSH into a remote server over VPN as well, it all seems to work; until there's some more data returned. A quick example would be an internal webserver. The default homepage simply redirects, so only sends back HTTP headers with a "Location:". I receive this on my computer, but when I request the actual page then (which isn't that big) I don't get a response at all - it just stalls. And it does this for other services as well, for example SSH. I can do a couple of things while connected, but if there's more than xx output it seems to do nothing. The connection remains active throughout all of this. Has anyone ever experienced anything like this before / know what the problem might be? Another user who has a site-to-site connection with this VPN using the -exact same setup- has no problems, the only difference is that I have around 200ms ping to the VPN server/network because of a very long distance (other continent).

  • DNS issue for internal website routing internet connection from remote location

    - by Michael Paul
    I have an issue that I could use some help with. Our company has a main location and a remote location. Previously, the remote location was connected to the main location through an internet connection VPN tunnel. The connection was pitifully slow at 1.5Mbps, so we upgraded it with a 75Mbps direct link. That meant the remote location lost it's internet access, so we routed their access through the main office internet connection. Everything works perfect except for one thing. The website we host is not accessible from the remote location unless the IP address is used. If I do NSLOOKUP on our website address from a machine connected to the main location network, it resolves correctly to the inside IP address. However, if I do the same from a remote location machine, it resolves to the website's outside IP address. Our internal DNS server(s) have a pointer and CNAME records set up, and everything was working perfectly before the connection was upgraded. In addition, the remote location has a domain controller, DNS server and DHCP server to service these requests at the remote location and prevent these requests from getting routed back and forth over the link. So I think was it happening is that for some reason the DNS server at the remote location is not resolving our website name correctly and passing the requests on to the routers, which then push the request out to the internet DNS system. That resolves the name to our external IP. This is purely a DNS issue, everything else works just fine. I am just stumped on this one. Any ideas on how to fix this? Edit: I forgot to mention that at the remote side of the link is a Cisco ASA-5505 and at the main office there is a Cisco ASA-5510. The link is connected between these 2 devices and the routing is handled in the 5510. Thanks, Michael
