    I have netgear n300 router which I had installed about 6 months back.

    Here is how the setup is, I have a local internet provider by the name of "Hathway" they have this modem which is in turn connected to the router and a wire from router is connected to my desktop.

    As shown in this pic below, except for the laptop I use a desktop rest all the connection is same

    enter image description here

    So with this connection and the below configuration, every thing worked fine. The desktop would work also all my laptops and mobile devices would connect and be able to access the internet without any problem.

    enter image description here

    Now suddenly since yesterday (with no changes made whatsoever to this config) all my laptops start showing the limited connection message and cannot connect to the internet.

    However the desktop which is connected can access the internet.

    Can someone please guide me on this.

    windows xp - Laptop connects to wireless router fine via ethernet but not with Wifi

    Here's the situation: laptop is Windows XP SP 3. Wirelss router is Thomson Speedtouch 780WL. I can connect to the internet fine with my laptop using an ethernet cable into the back of the router. My Android smartphone connects fine to the Wifi, but my laptop won't connect to the Wifi. I've tried repairing, disabling and re-enabling the wireless but no joy. This is using the Windows XP wireless client.

    I guess, given the fact that my smartphone is working fine, that the problem is with my laptop. Yet, I've connected to hundreds of wifi points before with no problem.

    One important factor that I think could be an issue is that recently, while in the UK, I installed one of those 3G USB dongles to use mobile broadband. It was from a company called O2 and it selfishly installed its software (a horrible thing called O2 Connection Manager) which not only managed the 3G connection, but also decided that wasn't enough, that it should also manage my wireless connections. However, it did work fine with any wifi connections I tried, but it seemed to depend on having the dongle plugged in (which I found infuriating). The problem now is that I am no longer in the UK, so I can't use the dongle. Could this be the reason behind my problem? I've no problem uninstalling that O2 software if people think it's the right thing to do.

    If you aren't attached to the O2 software, it might just be easier to uninstall that first and see if that fixes your issue.

    The WiFi radio may be turned off... if it's a laptop you can activate it with "Fn + F6"(there should be a sign for wireless on one of the "F" buttons at least...

    I know Dell laptops have a radio that comes with their Dell software that manages the WiFi - is the WiFi card deactivated?

    Perhaps you need to configure the router somehow... most often the default IP is 192.168.0.1
