MBP keeps forgetting my wifi

[Tainter]

I know this has been discussed before but is there any solution to this ?

Evey time it goes to sleep or i turn it off it forgets the fact that there is ANY wireless around. I have to look for the networks. Then if it wants to will find them and trying to connect to my own wireless network ( apple extreme) is a challenge .

I do have parallel desktop installed , could that be the problem ? ANY hints ?
here is some info

Have you tried an SMC reset? Here is the link to the Apple support page:

Sounds frustrating. Good luck.

Go to Applications/Utilities/Keychain Access/Log In Keychain/Passwords. Delete any references to your wifi network and start over. I had the same problem with an old PowerBook and that fixed it.

thanks but that did not work either .....

it always drops the
isp
server
Internet.

i almost gave up using it since it forgets the internet about every 5 minutes now.

It scans for wireless networks , but it finds NONE. after a while it finds them i join my home network and it starts all over.

It is not my router since my xbox 360 and my iphone have no problem staying connected for hours . Any other hints ?

I'd try power cycling your router and modem. Sounds like an overlapping of IP addresses.

Are you sure it is not your router? Have you tried taking it to another wifi spot? Even the local Starbucks should give you a baseline. If it works there, it is your router. If not, sorry, you've still got work to do with the Mac. But I think it would be worth the trip to rule out the router as the source of the problem.

My mbp didn't tell me when I had an IP conflict and I had the same symptoms as the OP. For me it was all resolved by resetting the router back to default settings, reconfigure and reserving an IP for the mbp at the router. Might be worth the OP giving this a shot.

I set the router to channel 10 instead of Automatic and that seem to have solved the problem . thanks for all the help
