Windows 7: Unstable internet connection when changing from cable to wireless

Unstable internet connection when changing from cable to wireless


I have this problem with my laptop. If i am using a cable to connect to the internet and then unplug it and switch to wireless connection, the internet connection gets unstable. The thing is it says it is connected to the right wireless connection AND it claims to have internet connection. - And i do - for a few minutes.. If i deactivate/activate the wireless internet i am able to surf around for a few minutes again, but then it does the same thing again - shows up as having internet connection but im unable to connect to it..

Strangest thing is that i am sometimes able to connect to the internet ONLY if another computer is using the wireless internet too.. It still shows up as recieving a nice signal with internet access even though i cant connect to the internet..

The same problem also occurs sometimes when im switching from one wireless connection (at home etc) to another (work etc)..

I've had this problem for a few months now.. Comming to think of it i might have had this problem ever since i got my laptop.. Rebooting my computer fixes it every time, but it's not a permanent solution.. Im running original Windows 7 Home Premium x64 which came with the laptop.. Also im not using static ip or anything like that - switching to static ip doesn't do the trick.. Running ipconfig /all command from cmd also shows me as connected to the right router.. The problem occurs every time i switch between cable and wireless and not only at my home or work but also at friends..
I'm not sure if i need to leave any more details, if i've left anything out just let me know.. Hope you guys can help me out, thanks in advance

Also im sorry if this is a thread comming up here a lot.. I've been searching for a solution to this problem for a long time, but i don't really know what to search for or how to narrow it down, so i decided to try my luck out here

It's almost certainly the settings on your WiFi adapter, unless you are in a really congested WiFi zone or your WiFi signal is very weak.

Step one; Open Control Panel, then Device Manager, look for Network Adapters, expand the list to show your ethernet and WiFi adapters. Right click on the WiFi adapter. Choose properties, and look under in particular the Advanced and the Power Management tabs. Turn off "allow this device to be turned off when not in use" under Power Management. In the advanced tab I cannot predict what your options will be as it's adapter specific - and in 90% of cases these adapters are set at failsafe values instead of optimal values.

Step two; Google the optimised settings for your adapter, or refer to the user documentation, and change anything which is handicapping it.

If problems aren't solved at this stage look in your Router or Access Point's settings. Try different channels. See whether the router (and adapter) are set to B,G,N protocols and adjust as necessary.

Should this not solve the problem then post back

Hi Qdos, thanks for the fast reply! I apllied the settings last night but it didn't solve the problem when i got home this morning But i did notice something else.. When typing the ipconfig /all command i am now no longer connected to the router - even though it says so if i click Properties in the connection settings (It says i'm connected to the router but with no internet acces this time).. But when i get another laptop to connect to the wireless it automatically fixes my connection too. This is my home network and getting another laptop to connect to the wireless internet has always fixed my connection too. Can this be router-related at my home network? I am starting to believe this is a 2 part problem - my home network which can be fixed with another laptop connecting AND rebooting - and other networks (home, friends) which i can only fix by rebooting.
