Unable to get signal downstairs

[jlyne1234]

Hello

About a week ago i bought a Belkin N+ wireless router which ive installed upstairs and it worked fine. Ive used it with the built in realtek adapter in my laptop without any problems for the last week. The desktop connected to the router works fine and my laptop also works fine when im in the same room as the router. However today randomly i can no longer get signal downstairs at all. I used to get 3 or 4 bars but now i get a wide range of errors when i try to connect.

Some of these errors are:

• Network appears on list of networks but when i connect it says "Unable to connect".
• I can connect to network but it says "No internet access" and i cant use internet or access other computer upstairs.
• I can connect with 5 bars of signal and no error appears but i still cant access the internet or network.
• I can connect but it disconnects itself and then says "No networks available" even though there are 5 other networks that it normally finds"
• I can connect and i get 5 bars of signal but it is incredibly slow - almost dial up speeds.
• I can connect but it then says "Identifying..." for ages and then says "Unidentified network - no network access"
• The network disapppears when i try to connect and the keeps reappearing and disappearing every few seconds.
• It says "connecting to network..." indefinatley.
• On very rare occasions i connect fine

I think its a signal issue but that doesnt explain why it used to work fine downstairs and now doesnt with no changes. Ive tried the following things to fix it with no luck:

• Resetting adapter and router
• Repositioning router
• Changing angle of antenna
• Performing a factory reset
• Trying several different channels on both 20mhz and 40mhz mode
• Changing to 802.11n only mode
• Turning protected mode on and off
• "Trusting" my laptops mac address
• Updating router firmware
• Updating realtek adapter driver
• Uninstalling and reinstalling adapter which sometimes temporarily fixes it
• Turning off power saving for adapter
• Changing adapter to 802.11g which fixed it once
• Turning off security

None of these things have permenantly fixed it. Windows 7 troubleshooter says "Investigate a router or access point issue" or it says it fixed "A problem with wireless adapter" but the problem is never fixed. Ive used network stumbler and when these problems occur downstairs the signal fluctuates significantly but it is still fairly high. For me it seems it could be signal, the router or the adapter as the problem is sometimes fixed by driver updates but it then stops working again. I have no other wireless devices which makes it harder to find out which part is the problem. Any help would be greatly appreciated.

Thanks,
Jim

I have now tried every channel induvidualy and that hasnt solved the problem. It seems unlikely that its the router now

There is a very high probability that which ever A/V software you have installed is causing this problem. Happens all the time and it doesn't seem to matter which one because they all seem to cause similar problems such as you are describing. Also, those so called third party networking programs are also famous for creating problems like this.

It's usually required that you uninstall them completely in order to fix the problem.
