SOLUTION FOUND!!! (at least for me )
Warning, will delete all your Network settings
I also had this problem and the process to solve it is very easy, but no for the noobs
Fist, turn off W-Fi and then go into your System Perfences > Network and at the top there is a box, click it (I don't know how it's called cause my Mac is German ) Then, click onto the + sign. Name it Wi-Fi. Afterwards, create another one called FAKE. If this is done, delete all the other ones in the list, Wi-Fi & FAKE should remain.
Now leave that window open and go to Applications > Utilities and choose that one that looks like keys. (again, I don't know how it's called cause my Mac is German) Now, delete every single setting that belongs to your Wi-Fi and then quit the App.
Get back to that Network window you left open and delete FAKE and click onto Wi-Fi, then Activate Wi-Fi. Make sure that the box for notifiying if there are new Networks avalible is unchecked. Click onto the box upon it and connect to your Wi-Fi network of your choice.
Voilà! Your Wi-Fi should work correctly now
This could well come close to a solution, I have seen similar explanations to basically reset all network settigs, ad set them up from scratch. I have a few points of tought here, though. Points that should helLp to refine the core of the problem.
- Is this networking trouble also happening to fresh setups, I mean setups of computers without settings having been merged from a previous system?
That is an important thing that might have been cleared along the long path of this thread, sorry if that's already clear to regulars here...
- why do you make two network locations, as I guess you mean?
(You could switch to English very easily in the System Preferences, I have all my electronic in English, good for sharing solutions, good for applying solutions)
I don't see the point of making two, then deleting one... Does that mean you tried it without this odd step, without success?
- the Keychain thing (as is called the app with the keyring) is rather interesting. I had mostly all trouble solved by the method of removing old keys, and adding them again. I complained at Apple that this incompatibilty - or at least the numerous issues related to the keychain - is a very big failure in the consumer experience of the transition from a previous system to Lion.
It'd be good to know if the fix on both sides of the network preferences and the keychain gives an ultimate fix. I fixed my trouble long time ago in a similar way. I simply don't have the trouble anymore.
I believe the link I posted earlier is a similar fix, yet maybe not as complete... You basically erase all network settings (could be done elsewise as well) and delete the keychain info related to networks, and start from scratch...
A tip to add to above post: check the keychain info of your wifi networks, by double clicking relevant keychain entries. If necessary, copy - paste passwords into a text file before you delete these.
Alternatively, make a screen shot of the frontmost window being your keychain info:
'option' + 'shift' +'4' then the space bar
A camera icon will appear, and you can move your mouse to select this keychain window with that important info.
It will wait for you on the desktop...
Good luck fellows!
Glad it worked for you, @Tuskuno, but no luck for me. I will say that it managed to load my FB page, but it was very slow. All other pages timed out. Probably just FB server being more responsive.
My key symptoms continue to be:
- I can ping any host name without problems
- My browser resolves DNS name, but then cannot get through to hosts, or occasionally gets through but data comes in VERY slowly. E.g. It can take 3 minutes just to load part of a page!
The saga continues...
This is the world of low quality outsourced American products we live in today. Until the employment laws in China and the rest of the world start being enforced, factory employees will continue to work for peanuts, producing much lower quality products. While the corporations and lobbyists stuff their pockets, the slaves overseas starve and the consumers keep buying the crap.
Intersting article, but this is completely off topic... we are discussing a tecnical issue here, not ethics.
I guess we all are guilty by buying the 'crap'. And unless you own no technologic products made in China, you should have the brain to post such things in a relevant place, no?
The Software is completely made in Cupertino, the design, the quality is guaranteed by an USA company...
This is high technology, and your comment is off the hook.
// Let's please stay on topic //
No problem. I just thought I would throw that out there. Not completely off topic since I replied to someone elses complaint. When customers are frustrated with the quality of the products they purchase, I think they have a right to complain with the rest of the unhappy customers. There have been plenty of solutions offered so far in this forum, and I happen to be running 10.7.0 with acceptable performance, but by no means optimal. Let us complain, man. You are as guilty as we are for responding with the defense for Apple.
But I do have to admit, this poor quality of Apple products isn't completely new. I remember back in OS 7 (93-94?) when I had to wait for a year sometimes before installing OS updates since they would cause many other issues (conflicting extensions, lockups, unhappy macs, and infinite hourglass spinning).
I have been all over these boads looking for a fix to the wifi issues I have been having since I upgraded to Lion. Some where I saw a recommendation to Renew the DHCP lease. Go to Internet and Wireless>Network>Advanced>TCP/IP and click on the Button to renew DHCP lease.
So far this has seemed to do the trick for me.
I hope this helps.
I found a solution. I bougth a router!!!
Sinceraly i am very dissapointment of apple. I was hearing that mac didn`t have problems like windows etc. and the first thing that i saw is that Mac can´t solve a very simple proble like this, they don`t have the problem that there are a lot of different hardware like in windows but they can´t solve it . All the other things work pretty good, but i won´t forget this issue and the poor quality in the mac services.
dIn September after a month of frustration after downloading Lion. I too bought a new router and haven't had a problem since.I posted this and wondered why nobody commented on this. Just like Amigon above my connection problem was solved. I 'm just happy somebody else had the same solution. I can't believe this is still a lingering problem for people. I think I would have tossed the computer if i had this problem for as long as some people have.The router I picked up was an e genius, an inexpensive router that is doing an excellant job.I think it is definitely worth a try.
I agree , my Snow leopard worked flawlessly before I downloaded Lion. I think that the problems people have had with their Lion software are unacceptable. After a month or so of experiencing this and realizing that this problem isn't going to be fixed in the near future, the investment of less ten $50. compared to what I paid for Mac computer is worth it. I have had no problems for the last three month and it has saved my sanity!
Hi, I tried almost all the solutions posted here, none of them worked for me. My browser (chrome) says that it cannot resolve dns names. The only solutions so far has been for me to call my provider asking them to reset their modem, but after a while my router blocks again. Today I've used the wi-fi connection with two windows machines: no problem at all. What a shame, this is not a Lion, it doesn't even resemble a sheep.
