Q: Wifi Constantly Dropping in Lion

Did you happen to use the same SSID when you created your new network with your new time capsule? 

 

 

Indeed I did retain the same SSID and WPA2 password as I didn't want to go changing all my devices. Everything worked straight away and brilliantly... Much stronger, and of course no drop outs on my Lion MBPro.

I wanted a 2gb Time Capsule anyway, but the better wireless has been a bonus.

I have a new dual band Apple airport have have had the problems with several Lion machines (old and new machines, as well as Lion server and workstation). 

The interesting thing is that I didn't have the problem on my macbook pro at first (which was upgraded from 10.6.x to Lion).  But then I got a SSD and did a clean install of Lion to it, and thats when the problems happened.  Interestingly, that's also when my imac seemed to start having problems running Lion as well.  Before the fresh install on my macbook pro, both my macbook pro and imac worked fine. 

I wonder if a new airport with a new BSSID would solve the problem, for my current machines running Lion.  It seems that when people buy a new wireless router, the problem goes away...  Just a theory/guess...

It's repeating stuff I wrote before, but to reiterate, I had a 2008 MB Pro on SL and it was fine for 3 years. Then I bought myself a late 2011 MBPro with SSD and Lion out of the box..... and it "broke" my network.

Not only did the new MB Pro drop out ad nauseum, but the 2008 one did too.... Funny enough my 2006 Mac Pro didn't (in same room as the wireless router) and nor did my iPad2 and iPod, irrespective of where they were in the house.

Buying the Time Capsule has been an instant and permanent fix as I turned off the wireless signall from my router and connected the TC by ethernet to it. The TC serves the Wi-Fi now and I've had no problems for the last 2 or 3 weeks.

It was dropping out every day before, maybe a dozen times or more. Sometimes turning Wi-Fi off & on the top Airport icon cleared it straight away.... sometimes not, and it needed to stay off for 5 mins and then be turned back on, and it would be ok for either a few seconds, or if I was lucky maybe a few hours.

It is stories like these that really make me wonder if a new BSSID is what is fixing things.  What puzzles me though, is how the computers are remembering the old BSSID even when doing a clean install (aka, formatting the hard drive, then installing).  But even zapping the PRAM, etc, doesn't seem to fix it...  This is definitely a very curious and annoying problem...

In fact, I find it so bad, that I can no longer recommend Mac's to my clients.  If they had this problem with a new mac, it would seriously tarnish my reputation. 

Yeah, I don't know about buying a new router and such...I have no problems except for the iMac.  Both of my sons have MacBooks and they were upgraded from 10.6 and they seem to be doing fine.

Apple has to come up with a fix and quickly, because I too cannot recommend iMacs to my colleagues and clientele.

I cant connect to the internet either. It sometimes say 'connection timeout occured' or 'invalid password' or it connects but internet is very slow.

I dont know it is because of 10.7.3 update. I have tried everything that written on the internet. They fixed sometimes but i couldnt fix it permanently.

Is there any permanent fix have you known?

Thanks

yea... create a new location in your network preferences of your system preferences and minus out your wifi on the left hand side of your network preferences of your sytem preferences.

yes i tried that. didnt work

I didn't get that to work for me.

FYI:

I did think that maybe perhaps I had an IP in conflict, but I don't.

restart the computer holding down the shift key... this puts it in safe mode... see if you are able to have internet in safe mode.

In safe boot only a wired network connection is available.

The wireless drivers are not loaded during a safe boot.

My friend, you are mistaken. This is not Windows. I just restarted my mac book pro, in safe mode, and i was able to connect to the internet wirelessly.

It is possible... did you see that article about malware a few pages back at https://discussions.apple.com/thread/3190651?start=1500&tstart=0

I mentioned:

I just read an interesting article.http://compnetworking.about.com/b/2012/02/18/what-the-fbi-internet-dns-shutdown- means-to-you.htm

Carlo i tried to connect in safe mode but couldnt connect =/

Your using Lion right? ok good. Well that is not good not being able to cnnect to the internet even in safe mode. ... Maybe Allan is right for desktops, but i tried with my macbook pro and was able to get connected. You would think it would be the same thing, right? right... i am glad your agreeing with me. Do you have a back up using time capsuele - very important it is highly recomended? Have you run Lion recovery or Disk Assistan in the past... if not i would recomend you run disk assistant. (and you are sure that you were not able to connect to the internet when you opened safari in safe mode, even tried clicking network diagnostics?....hmmm). you need a flash drive (about one gig or larger). open your utility folder located in your applications folder stck the flash drive in the usb, then run the program (located in your utilities folder called Recovery Disk Assistant. After it is done installing it on the flash drive, you will need to restart your computer with the flash drive connected and you will have hold down the option key. When the menu comes up, you are going to run disk utility to repair permisions, and when that is done your going to reinstall Lion. when that is done, your going to close out of that window and restart. let me know.
