    This is happening when I connect to the VPN from my home internet. I'm using Modem and Wi-Fi router. Internet and IM itself work fine.

    How can I troubleshoot this problem, I'm not sure if this is from Wi-Fi Router or Modem or my Internet?

    Office Wireless internet disconnects too frequently
  • Gaurav Sharma

    I am not a network expert (please pardon my bad explanation), but this problem has made me very upset.

    In my office internet is shared among 15 users with the help of a wireless ADSL2 router. Actually this router is connected to another ADSL2 modem/router (the main one), We all work on laptops having wifi cards. The problem is that the internet disconnects quite often. Although the router shows all the lights on and blinking but I think it is not able to supply or share the internet with all the users and hence disconnects.

    One is able to surf when he switches off and then switches on his wireless a couple of times. All the nodes are being assigned IP addresses dynamically by the router.

    Thanks

    15 devices is quite a lot - is it a enterprise class wireless router or a commercial one?

    It could be the router just can't keep up. On the other hand, if it is every device, this is almost impossibly to help without coming to your premises - I would say off the top of my head, check everything for interference, Microwaves, lights, or anything else that is wireless.

    Edit based on more information.

    On a few of the devices, can you try the following on any machine- (Assuming you know the IP of your router - lets say 10.0.0.1 for the first one, and 10.0.0.2 for the second in these examples

    Open up three command prompts,

    In the first type:

    Ping 10.0.0.1 -t

    In the second type:

    Ping 10.0.0.2 -t

    And in the third type:

    Ping google.com -t

    (Or your favourite ping-able site!)

    Next time the internet goes out, look at all open windows and see where the break is, You should be able to say if it is the router you are all connected to, the router that acts as the modem or the ISP itself.

    Is this on a stock commercial/household wirelesss router?

    You may want to try an alternative firmware such as DD-WRT, Tomato, or Open WRT. I've heard that they are better at serving multiple users. Also, as Wil says you should check any other devices that may cause wireless issues. Maybe it would help to keep of log of when it disconnects and look for patterns.

    At home I have the same problem currently. When I check the "radar", I find about 20-25 neighbouring APs. That makes for a lot of interference. Only in direct neighborhood of my own AP I receive decent speed and an interruption free connection.
