Mac OS Lion: Massive wi-fi-problems?

I too have had some problems with AirPort (MacBook Pro 17' Mid 2010) after upgrading to Lion. Yesterday and today my connection to my Time Capsule just stopped working. Yesterday to fix the problem I used the AirPort Utility and stepped through all the setup screens changing nothing and my connection started working again. Today, I stopped and started my Wi-Fi and that worked. Hopefully a fix will come out soon.

I have two similar threads about this issue. After you boot your machine, tell it to restart. When it restarts, wifi is functional again (but for how long is hit or miss). Every time you shut down your Mac for a few hours, you need to start it twice to get wifi working. Seems to be a major bug in Lion, but when I called Apple Care they tried to tell me it is some new feature. Luckily wi-fi is functional for me for over 2 hours after repeated restarts. I am giving it only 5 more days before I revert to Snow Leopard. Suggest you consider the same.

"Welcome to Lion." 😁

My iMac is less than a year old. Bought Lion as soon as it came out even though I knew from years of experience never to buy Apple's first offering of anything. I've been having the same problem with Wi-Fi/Airport/internet and same outcome every time the problem was supposedly fixed. Apple are apparently "not aware" of any such problem.

The amount of time I've wasted repeatedly opening Network Prefs and using Diagnostics to solve the problem for a few minutes is just not worth the hassle. The differences between Snow Leopard/Lion are almost invisible to me plus since installing Lion I've had start-up problems, my system has slowed and my patience has just run out- I have had enough!

I know I'm going to have to spend hours creating a Time Machine backup, erasing & re-formatting the drive, re-installing Snow Leopard but Apple are asleep on this one!

Hey-ho!

Is it the Wi-Fi connection with the router or the internet connection over Wi-Fi?

Wi-Fi connection with my router still excists only not conneted to the internet.

All my other devices work normally only my iMac with OS X Lion doesn't.

I only use Wi-Fi to connect to my router for internet use. Mac Book Pro (using Snow Leopard), in the same room, does not have the same problem at any time. Wi-Fi on my iMac seems to keep dropping the connection to my router and this started immediately after restarting with Lion installed.

Hi aidanmac

try going to NSharing and unticking Internet sharing then click it back and watch the grayed out icon at the top with an arrow , should be solid not bars and the arrow pointing up.

OS X Lion: The world's most advanced desktop operating system doesn't even connects trough wifi. Think different or crash different.

Hi

Did you try try going to Sharing in preferences and unticking Internet sharing then click it back and watch the grayed out icon at the top with an arrow , should be solid not bars and the arrow pointing up?

Hi Guys, sorry I'm a bit slow getting back on your suggestions but I can't seem to maintain a connection to the internet with the current rubbish OS I'm using - oh yeah, Lion, that's what we were talking about LOL.

Anyway - re changes to Sharing - been there, done that, no effect!

Planning to wipe later today and re-install Snow Leopard - at least that works!!

Later

Hi

Does the grayed out icon at the top have bars or is it solid with an arrow pointing up? Looks like a fan.

I, too, tried all of the suggestions I could find...deleting and recreating wireless interfaces, forgetting the network, pram, etc. Then I tried something I couldn't find anywhere and I haven't had a problem for a couple of days now. I noticed that I had 2 entries in keychain for my wireless network password. I deleted them both, "forgot" my wifi ssid, turned off wifi, rebooted, and then turned on wifi, found my homenetwork, provided a password, and voila! I have no idea if this is what the problem was, but it seems reasonable that my wifi didn't know what password to use. I haven't seen this idea suggested anywhere else on the net, and I don't want to imply that I "know" for sure this is the answer. But, it seems like another reasonable step to try....''

Seems like some things work for some people and not others...... I have tried every suggestion even the keychain idea and NOTHING has worked. My Wi-Fi is still telling me "No hardware installed", so one moment I was streaming audio, then no hardware between a major system crash system. I believe my Airport card is now damaged.

Hi! For me the answer was - and remains, as I've just tried again without it and the connection dropped immediately - something I found on the OSXDaily site (http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/). This is a simple and, I've found, extremely effective workaround until the problem is fixed, which it wasn't in the 10.7.1 upgrade. Give it a try!

Another Idea: Maintaining Data Transfer

Another theory is that when data transfer stops, the wireless connection inappropriately drops. You can avoid that by simply launching the Terminal and pinging a random address, this causes a miniscule amount of data transfer to occur and that can be enough to maintain an active network connection.

• Launch Terminal (accessed at /Applications/Utilities/Terminal or by using Spotlight)
• Type “ping yahoo.com” at the command line and you will see something like this

• ping yahoo.com
  64 bytes from 98.137.149.56: icmp_seq=91 ttl=52 time=27.806 ms
  64 bytes from 98.137.149.56: icmp_seq=92 ttl=52 time=27.763 ms
  64 bytes from 98.137.149.56: icmp_seq=91 ttl=52 time=27.806 ms
  64 bytes from 98.137.149.56: icmp_seq=92 ttl=52 time=27.763 ms

• Just let that run in the background, it isn’t resource intensive

Dumped Lion and re-installed Snow Leopard 7 days ago and BLISS - no more problems with Wi-Fi and in going back I confirmed for myself that there is very little user difference between the two.

See you all again around 10.7.9
