Lion Wi-Fi connectivity SOLVED - Should work for many, perhaps not everyone - DEFINITIVELY worked for me!

OK everyone... Here is what worked for me... While this is sure to help "some" it is unlikely to help all, but I assure you that it DEFINITEVELY fixed my problem.


If only I could get Apple to throw me an iTunes gift card, or nice leather Smart Cover for my iPad for all the time I vested trying to get this issue resolved - Better yet, how about an iPhone? - lol


First my symptoms were; Dropping Wi-Fi connectivity after Lion install - I could get a very intermitent, transfer of small amounts of data (about 300kb) then the connection would halt. So effectively I could get (some) text-based emails, but internet browsing was a no-go.


I spent three hours on the phone with very helpful Apple techs, but many of the things they needed me to do were internet-connection reliant, so thier efforts were fruitless. I decided to call my closest Apple store with a Genius bar, which is about 40 miles away, made an appointment, and brought the computer in...


I explained the issue to the tech, he said he could not see any known issues or notes on a "fix" yet while I was there a lady called with the exact same problem... I told them to get ready for more calls as more and more people run into this issue. Anyway... Since I could not connect to WI-FI (the ONLY method of connecting to the internet I currently have) I was unable to get sofware updates and make a network connection, so I was basically stuck.


Keep in mind, I brought my computer in, so it was unplugged for some time... He connected the computer to their network/internet via Ethernet cable, powered the computer, and had instant and immediate access to the internet, then did two things... One was to use spotlight to search for the word "Java", then click on "Java Preferences" - This did a "software update" for Java, THEN he did an actual "Software Update" from the Apple icon (which my computer was up to date) - He then unplugged the Ethernet cable, did a shut down, then reboot, and BAM! - INSTANT WI-FI - No drops, blazing speed, great connectivity!


So for al that have tried every other trick, workaround, or voodoo to try to get things working (like I did) - Perhaps the above process may work for you too? - I assure you that it has fixed my issue, which was EXACTLY as many of you have described here - And it works PERFECTLY! - No band-aids, no patches, no workarounds, just a perfectly working iMac once more!


So in summary:


Unplug your computer for at least a minute or so...


Connect Ethernet cable from modem


Power-up computer


Do Spotlight search for "Java Preferences" click on the Java Preferences app to do a Java update


Then do a "Software Update" from the Apple icon drop down


Then do an actual shut down


Then Reboot


Once rebooted, I had to initially select my Wi-Fi connection as I did not have it setup as a defualt (you may not need to do this)


The first few pages I tried to load took a short while, then the Wi-Fi connection took hold and now everything works perfectly!


I hope this process helps at least some of you, as it has for me!

I earlier replied that this seemd to solve the problem. However, I replied too soon. It slightly improved the connectivity, but the same WiFi problem exists at random intervals. Not sure wheter I reported it or not, but at intevals it knocks out all the WiFi in the office. I have to reboot my FIOS router when it hangs up.


No doubt this is a serious Lion bug. Surpised that there has NO feedback from Apple!

This didn't work for me immediately, but there was also a weird quirk in my experience...


When WiFi started to drop, I logged into my router using my iPhone and changed the band from 2.4GHz to 5GHz. From that point it seemed that Lion only wanted to connect if the band was set to 5GHz and half the time wouldn't even see my network otherwise. Unfortunately I had to switch it back to 2.4GHz because the PS3 doesn't have 802.11n. Eventually though the only way to get online was with an ethernet cable.


I tried this and initially it didn't work, but I logged in again and switched the band to 5GHz. It connected almost immediately. I logged in one more time, changed it back to 2.4GHz and set it to b and g only, disabled N, and it's been solid for almost a full day now. It finds the connection when it wakes from sleep, it's fast and everything seems in working order again. I would definitely suggest trying this but if your router is dual-band give that a shot too, it worked for me.

Having started a thread on wifi and Lion

https://discussions.apple.com/thread/3209242?answerId=15735140022#15735140022


I left it a few days and then spent a couple of hours trawling through the hundreds of messages about wifi and Lion I came accross your post .


Now the thing that struck me was although the genius bar guy had "no knowledge of this problem", he seemed to know exactly what to do fix it. Now we all know Apple likes to keep this pretense that all problems are "new problems"

So I tried it and it worked for me! So give it a go, it only takes a couple of minutes and who knows you may just get 5Ghz wifi working.


Having spent 34 years working in IT hardware there is very rarely a new problem. I know very little about software, but I think I'm right in saying that Lion does "something different" with Java, because I had re-install it to get photoshop working after installing Lion. So maybe "something different" is where the problem is..........
