Q: Lion WiFi Connection Problem

This may have been answered many pages ago, so I apologize for asking again, but is this on an upgrade or clean install of Lion?  I'm on a Mid-2010 13" MBP and I'm plagued with this problem as well.  My network at home consists of a recent gen Airport Extreme router and a 1st gen Time Capsule as an extender.  This is driving me absolutely bananas.

Here is a quick fix:

Hope this may help a bit.

The second I installed Lion the internet became unstable. I thought it was the modem and router for a while, but couldn't figure it out. Then I noticed these posts and realized that every time I opened the Macbook 5.1 I upgraded, every connection in my house would drop(my Xbox 360, and other two macbook pros(running snow leopard) were disconnected as well). When my Macbook 5.1 was closed (and router restarted) the internet worked flawlessly with all devices for long periods of time. The two macbook pros running Snow Leopard work fine. I wish Steve Jobs was right when he said Apple products "just work" because this is just dumb. Why would my Macbook 5.1 running Lion disrupt all my Wifi connections? And I have tried every fix listed here. ALSO, I did a clean install of LION from a disc I burned. FRUSTRATION!!!

This is crap.  I am having problems with wifi and a wired connection.  Both work for 10 seconds then hang for 20 seconds.  Fix this apple

SOLVED SOLVED SOLVED I solved the problem i must be god.  I have read all of the forums and everybody had gone so deep on how to solve this that i got lost, are you ready for the solution:

I changed my router from my bt latest we dont drop signal crap back to the router i have had in the cupboard for years my trusted netgear.

now with the bt router i was dropping every 20 or 30 secs and so far touch wood i have not dropped once in 24 hours since putting my old 5 year router back on.

but before i can get to excited i did have to give up the range the router can cover, i mean the bt was great it covered a great range but what is the point of range if it just keeps dropping signal.

SOLUTION THEN IS:  change to an old router.  i forgot to mention my imac is 6 months old and has lion, my bt router did not even like snow leoperd.

Knowing my luck this wont work for anyone else.

hope this helps thanks andy

could you post the make and model of the router which did not work.

and the make and model of the router which did.

cheers

the router that is still working is Netgear DG834G v4  and the one that is not working is the 2 month old BT Home Hub 3.0

Still no drop out 27hrs later

thanks andy

ok so your old chipset in the bt home hub was a Atheros AR9227 chip.

In the v4 of the 834G they switched to a Broadcom chip (intel)

So you are another person just like myself that switched from a atheros based chipset router to a broadcom and it solved the issue..

I think its looking more and more like LION has its problems with certain router chipsets.

thanks for info.

Coming in to this discussion a bit late but ever since I installed Lion I keep dropping the WiFi signal.  I have a first generation Airport Extreme and a 27" iMac with Intel Core 2 Duo processor, so it's a couple of years old now but still in very good nick.  It does appear to be an issue with Lion, which I hope the boys and girls at Apple address soon.  It's playing havoc with my social networking!

suggest ethernet cable if you can until its resolved from their side. but check out this forum thread there is a lot of suggestions you can try.

That is very interesting, I have been using the Mk 2 Home Hub, initially I was having the drop out problems solved by either a SMC reset or moving the hub ID to the top of the available networks list and I have been stable for the past week, your note is timely as BT delivered the new wonder MK 3 home hub this morning. I will approach it with care this evening and report back.

you will cry if you put that new bt home hub on.  what i found with it was that it kept rebooting itself every half hour which i put up with, but was getting greif off the misses and kids because every time they wanted to watch iplayer or sky through xbox, or go on apple tv it just kept buffering and rebooting, and then when i installed lion after being locked out of apps for days it just said no and wi fi just kept dropping.

I think the comment about the chipset in different routers is where the answer lies.  maybe im a conspiracy artist but it seems that if you have a chipset that is intel then it works and funny coincedence is that apple use intel i presume.

my old bt router i had before there new all singing dancing one did the same just kept dropping but only once a day untill i changed channel then it was only now and then.

good luck guy's my wi fi is working so all fine and dandy this end.

thanks andy

I have the same problem witha new Macbook air I just bought.  I can understand why there might be problems with connections between that computer and the router but cannot for the life of me understand why it brings the whole system down when it wakes from sleep.  I have to restart the router and the computer.

Seeing the sheer amount of people having this problem I realise this is not unusual for Lion so why do we still have this problem? Apple??? Every since I upgraded to Lion (I have the MacBook Pro 17"

2.93 GHz Intel Core 2 Duo) the connection (wi-fi through Time Capsule) drops every 15 minutes for a brief period it is true but enough to aggravate even the more patient user. Please please please solve this Apple - upgrade the software for the AirPort or do something by the grace of the divine authority

Your Air may be having this problem due to a known and from what I gather, perhaps unresolved power issue with the Air.  I owned an 11 inch for a week when they came out. In that week it would not wake from sleep, it would not charge when in sleep. when i went in for a surgery after 5 days, I powered it off with a full charge and two days later when I turned it on the battery was drained.  It then started not waking from sleep ever. Also, it would go to a black screen and turn off.  I returned it for a mbpro that has had no issues.

On the extensive thread I started, and the issue wound up in the news on sites like huff post etc. just after release, many came to believe it was a definite issue with flash and using Safari.  When some owners stopped using Safari for Firefox or Chrome, the problem got better or stopped.

Safari is tied into the network and wifi connection, network diagnostics. It is as might be expected not a very flash friendly browser. Apple's distatste for flash is well documented, but alas, most of the internet still uses it.

Try researching power issues with MBAirs.

This is the thread that started it back in Oct 2010.
