Thanks for your reply. No all wifi setting were still there… Not sure if wifi is better yet.
My problem was actually a general wifi slowdown after which I would need to change the channel and then it speeded up again. But this was happening very often. In the meantime, no slowdowns.

Time will tell…. One other thing we did because we were seeing odd drop-outs of Wifi was to switch routers. We were using a SonicWall, which is incredibly difficult to configure. Oh well! Open network perferences. Advanced Hardware Configure, set this to manual Type in in the box.
Google , while all my co-workers can. I think it may be faulty hardware. Same problem here. This does not seem to be a Mountain Lion issue per se… But maybe an update to the firmware on the Airport when ML was installed. I have an AP Extreme mid model that is causing a slowdown. I have two other access points, one an older D-Link As fast as the AP used to be before the problem. The other access point is the unit that comes with Uverse, an Switching between the units that are all active at the same time shows that the Airport is not working correctly.
No changes were made to the Airport settings, save the ML install. I have a Mac Pro that seems to lose ethernet connection once the computer goes to sleep. Only way to get it back is to restart the computer. Also had wifi problems on my macbook pro and first edition macbook air. Looking forward to a solution, Actually had more issues with Lion as far as software compatibility, so can live with the inconvenience for now. Apple is always forthcoming about problems with its products, so I am sure these issues will be fixed in no time.
I forget where I saw this suggested. Turning off Bluetooth has resolved the issue for about a day so far for me. Curious if it will last. None of the other solutions on the web worked even temporarily — creating new location in Network, etc. Same issue as everyone — late MacBook Pro — working fine and upgraded to Mountain Lion — now, as soon as computer sleeps, no WiFi — have to restart or even shut down completely to reconnect happens on whatever network I happen to be on — huge pain since I travel and am constantly closing lid of computer which causes the problem almost everytime.
I had a network here that my mac did not find anymore. I solved that issue by deleting all networks my mac remembered.
After that I did see the network and was able to connect again. WiFi not working as it did before install.
Went to Apple Store, guy sez everything OK. Got home, still not working. Router OK for PC. Even though WiFi connection strength indicates full signal the connection becomes terribly slow.
How To Fix WiFi Connection Problems in Mac OS X Lion
I am typing this on an iMac with Snow Leopard which is just 1 meter away from the MBP — not having these issues connected to the same exact router via WiFi. Thunderbird looses connections to mailboxes. Firefox somethimes even times out when looking for google. Im using the latest driver for my adaptor. So please let me know how I can fix this issue.
Dude,you saved my life tonight.. Thanks, it seems that you have a very large knowledge on this subject. We can see the router on airport, but it seem that it would not aloud us to get to server. Any ideas? Handy thanks! Always-on Connect-on demand being set to Connect on demand instead of always on. Thank you! Thanks for nothing Chriswrites.
Very ambiugous instrucitons. I rarely comment on articles, but I will here to warn you of a problem with your instructins. Got to step 2 on the remove and re-add wifi. Removed wifi service, went to re-add, but your instructions are unclear, guessed that I was to add the name of my wifi service and now I have a status message that says my wifi service does not have an ip address and cannot connect to the internet.
Nor can my mac find the network. Luckily i have clicked the revert button and undone these poor instructions. Please review these instructions for users of os Lion for mbp version They are NOT helpful. I have the same problem When deleted the wifi could not connect it again saying no IP address for the wifi? Thank you Chris. I was trapped on an overnight layover in Narita Japan.
Nearly six hours were spent googling and trying suggestions found with my iPhone.
