ok, my laptop will connect to my wireless network no problem the first time I try. If I turn off the laptop, or leave with it, then turn it back on, it won't connect to the network again unless i reset the router. It just sits there and says establishing connection.

my wired pc and the laptop are both running windows xp, and the router is a trendnet tew-432brp. the network is protected with a wpa2 password

So it will connect just fine, until after the connection is lost and then doesn't reset... I would log into your router and make sure everything checks out right with your DHCP server... I might also check into how long the leases are... I would also make sure the DHCP client on your laptop is working fine... Also just as a heads up.. It might be possible that you may need to flash the firmware for you router, or even buy a new one... Sometimes routers can just go out without any reason, or even due to power outages(more rare for that though)...

Do you experience any discrepancies with the connection on your Desktop? Have you done an AV/AS scan recently(updated definitions of course) on the Laptop recently? Sometimes virus' and spyware can cause for network discrepancies...

Right, we can connect to the connection fine, but if we turn off the lap top and turn it back on we can't connect again until we reset the router. i'm not sure how to check out my DHCP server, all i know is that it is enabled. The lease is a week, but this problem happens daily. It runs fine on the wired PC, and the av/as is run often on both computers

It is possible that you may have to flash your firmware in your router... It is also possible that you may need to get a new router, or re-configure your router... Just the same it could be a AV/AS problem... Even routers can get virus's, though it is very very rare, it can happen... Though I would suggest scanning both computers again, if that doesn't work; I might take a look at getting a firmware updated, or replacement for your router, and flash the firmware for the router... (if you need help with that I will do my best to guide you).

ok, well my pc is no longer hooked to the router at all, and i was still having the problem. i did download and install new firmware to the router, so we'll see if that does anything, i'll also run a couple other scans for virus' or spyware.

I would recommend doing the virus and spyware first... Cause if you make a mistake or something just goes wrong with the firmware, you can brick your router, and it will be utterly useless...

:thumbsup: well i forgot that i had to wire the internet to the laptop to update the firmware on the router. so when i checked on it those few times in a day i totally forgot it was wired in.

soooo...... i'm still having the same problem. when i turn the computer on after it has been connected once before, all i get is limited connectivity.

very annoying to have to restart the router every day

Hhhmm.. And have you done a AV/AS scan? Also what programs have you used, if you have? If you haven't I suggest using either Adaware, or Spyware Terminator, and Avast, or AVG...
