Windows 7: intermittent wireless stalls

31 Jan 2012   #1

Windows 7 Professional (64bit)
intermittent wireless stalls

Sorry if the subject is cryptic but its about the best way to explain the issues.

basically, sometimes l could be browsing and for no reason l get DNS errors with both firefox and IE, at these times my router also becomes inaccessible when it happens.

before ppl ask it has happened with two different wireless dongles (one branded Zoom and the current branded Tenda) furthermore when it originally started l assumed it to be the dongle which is why lm using the Tenda USB adapter, the strangest part being that when it originally started l was using a different setup, lve since done a rebuild and the only things that have stayed the same is my storage hard drives (everything else is different).

now you may point fingers at my router however lm not so sure thats the culprit because l also have a laptop which doesnt suffer these issues which also connects wirelessly and l have experienced this problem while using my laptop where my system just sort of stalls wireless traffic, you may ask about security software which l shall add is pretty much the same (l use bitdefender and peerblock the only addition being there maybe a few more lists added to the affected system tho disabling doesnt seem to help when the issue occurs).

all l can say is in addition to browser issues with browsing, sometimes my IRC client will disconnect from the chat server l run (its usually open all the time) so l guess the timeout periods dont always kick in when it happens and also skype will have trouble staying connected. l have updated my drivers in the past week and it hasnt happened as much (touch wood) as it did before but its still happening what l can tell you is the adapter lm currently using is a W302U (which lve just found out is discontinued) and the driver lm using is for the chipset rather than from the makers site because l originally found it ran better than Tenda's own software as it lacked all the crap that came with it.

If you plug your pc directly to the router do you still have problems? In either event, go back to wireless for the next questions...

Are your Zoom and Tendra dongles both old (pre-Windows 7)? What are the specific model numbers?

If you try pinging an ip address, do you note dropped packets?

If yes to the ping question, if you ping your router do you have any problems?

If you boot into safe mode with networking, do you have intermittent internet problems?

never been into safe mode and pinged.. however the fact that my laptop has no problems when it happens and lve happened to have it turned on seems to indicate a local problem. l admit lve not tried pinging my router when it happens.

tho l did notice now l think about it that occasionally when it happens l skype has been able to send and receive messages.. its only recently skype looses connectivity when it happens. l will admit the tenda is pre-win7 however the zoom adapter was purchased at the same time l got windows 7 because originally the hardware testing tool l had said the old card wouldnt work and considering the issue has affected two different systems it just seems strange.. tho in the case of my current adapter it feels like small stalls my zoom adapter was loosing the wireless connection which has never happened on my laptop.. in fact it seems to connect faster to the wireless than any of my systems do.

the model of the current is W302U for the life of me l cant remember what the zoom adapter was but l believe it used the same drivers.
