Q: wifi problems

Apr 16, 2013 1:13 PMby Baby Boomer (USofA),HelpfulTry the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.
Research Knowledge Base for network problems that pertain to the OS that is currently installed on your computer. See these basic networking KB Articles: http://support.apple.com/kb/HT1401 AirPort troubleshooting guide

Also, run the Airport Utility app which is located inside the Utilities folder.

If using a Linksys router, contact LinkSys Customer Support and/or post in their forums.
If using Apple's Airport, please re-post over in one of the AirPort Forums.

Apr 16, 2013 1:44 PMby Psico,Thank you for your reply, Baby Boomer.
I just changed the channel randomly from 13 to 8 (Europe) to see if it helps. I don't think that's the problem though, I have other devices connected and those work fine (except for the fact that the connection isn't that good and sometimes there are problems, which are occasional).
I have been rebooting my router on a regular basis and the connection is sometimes reestablished, however what usually works best is the diagnosis tool (that you also mention). Usually, it doesn't take long until I lose connection again after running the diagnosis.
I am using is a thomson technicolor TD5130.
I also tried to find a solution online before posting this, but I couldn't find anything that helped.

When selecting a channel, most people seem to go for the least congested, this is not always the best option as there are many other signals other than wi-fi sharing the allocation. All you can do is try a few channels and see if any are signifincantly better.

Apr 19, 2013 7:10 AMby G4PYR,Where possible all my kit here uses 5GHz as there is too much activity on 2.4GHz where I can see at the moment almost 40 networks. On 5GHz all I can see is a neighbour and myself and the speed is far better.
Certainly in my immediate area there is so much stuff on 2.4GHz that it's next to useless for a decent speed. In my office alone I have a wireless keyboard, 3 wireless mice, a bluetooth mouse and a bluetooth keyboard, two smartphones plus two laptops all on the band. Two neighbours either way also have networks on 2.4GHZ. On 5GHz I have two iPads and this Macbookpro and that's it.

If you wish, I can request that a HOST transfer this whole thread over to the Lion forums. Perhaps users there who are using the same OS system as yourself can offer new clues as well as suggestion.
