    Hello

    I have a Toshiba (Windows 7) laptop with a Realtek RTL8191SE Wireless LAN 802.11n PCI-E network card.

    Lately I have returned home after travelling for a few months only to find that whenever I'm in my bedroom, my Internet will disconnect for no reason and whenever I troubleshoot problems it fixes itself and says the error was "Default Gateway was not found" Only to happen again 30 seconds later!

    Sometimes it is fine for almost an hour and sometimes it disconnects 10 times in 5 minutes!

    This hasn't happened anywhere else (and I travelled all around the US/Canada using various WI-FI connections) and it only happens in my bedroom! If I walk into the next room it works perfectly without disconnecting at all.

    Does anyone know what the issue could be?

    - I'm pretty sure my network card is updated

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If your only email accounts are free (Hotmail, gmail, etc.) try this direct link. If you need help with a screen shot see TSG Posting a Screenshot. FWIW to take screen shots with Windows 8 or 7 or Vista I prefer to use the built-in Snipping Tool.

    Thanks for the replies - I disabled ipV6 - it kind of feels like its better but it still happened 3 times today.

    I also didn't bother changing my channel as there was only 2 connections in the area and the other one was using a different channel

    I attached the Networks screenshot

    Please show a Xirrus screen shot for a time when you have suffered a disconnect, and this time please show the Signal History graph as previously requested. It would also possibly be helpful to see about a minute of the signal history when you have a good connection.

    This is my signal history graph when its all working fine...I think that is what you needed? I'll take another screenshot when it disconnects which shouldn't be long...

    That indicates a problem with the router, the adapter or the adapter's driver. Unless you were moving the PC away or some obstacle was moving into the signal's path (or something like a microwave in or near the path being turned on?).

    Since you said earlier

    I'm thinking obstacle or maybe defective router but the signal is so much stronger in the next room that the dip in signal strength is not fatal.
