connect to the ASUS RT-13N wireless,

That one? -> http://usa.asus.com/Networks/Wireless_Routers/RTN13U/

You first should check that the Firmware of your ASUS is the last. Asus provide new Firmware and WLAN update for the Router -> http://usa.asus.com/Networks/Wireless_Routers/RTN13U/#download

Lion (OS X 10.7.x) require that the local Domain Name is set to "local"

The following are the factory default settings for your ASUS:

User Name: admin

Password: admin

Enable DHCP: Yes (if WAN cable is plugged in)

IP address: 192.168.1.1

Domain Name: (Blank)

Subnet Mask: 255.255.255.0

DNS Server 1: 192.168.1.1

DNS Server 2: (Blank)

SSID: ASUS

You should change the Domain Name to "local"

As you had upgrade to Lion from 10.6.8 you should, according to Apple's support hotline info, eventually delete some files on the Mac because some configuration files may get damaged or corrupt by time, after updates or upgrades and should get deleted occasionally.

Switch off wifi on the Mac.

Then go on and delete the files mentioned below.

You will find the files on your system drive (not your home folder) as follow:

(Because you are using Lion, the Library is hidden. You have to use (menu bar) "go to" -> "go to folder" on finder to access them.)

/library/preferences/com.apple.preferences.accounts.plist

/library/preferences/com.apple.preferences.sharing.plist

/library/preferences/SstemConfiguration/preferences.plist

/library/preferences/SstemConfiguration/com.apple.airport.preferences.plist

If there are files in this folders with the same name but additional .orig at the end, delete them too.

It is possible that not all mentioned files are on your system. That will be ok.

The files will get newly created by system on reboot.

For that reboot the machine.

Join your wireless again.

Still struggling :-(

I was streaming music to my zeppelin Air and it stopped mid song, Internet wouldn't respond and when I checked wifi it cold not see ANY networks.

My iMac usually see around 6 networks and for me this proves there is a problem with my iMac and not my network.

My phone and iPad did not lose any signal and I could stream music from my phone straight away.

Kernel in console says

Airport link down on en1 reason 8 (disassociated from station)

I am talking to apple support and hope to resolve this soon.

I've been struggling with this one all day. Sluggish, intermittent wireless connection, dropping out - base station not even showing up, so - plugged the ADSL modem into the extreme, then plugged an ethernet into my imac and configured like that. Then tried connecting with my laptop downstairs  - no success. Wouldnt pick up the network, connection timeouts, wouldnt accept passwords... then, in Airport Utility, I just changed the broadcast setting to 5ghz and its working great. Pain in the arse, I was about to try reinstalling Snow Lepoard. Hope this helps!

My MacBook Pro has been intermittently slow to re-connect to wi-fi after waking from sleep ever since I upgraded to Lion.  I've tried many possible solutions, and nothing's worked.  I tried downgrading the IO80211 kext, which is supposed to help only for Atheros chipsets, according to this website:

http://rys.pixeltards.com/2011/09/04/osx-lion-wifi.html

I have a Broadcom chipset, but I was desperate, so I thought I'd give it a try.  The verdict: Downgrading the IO80211 kext didn't help, but it also didn't hurt.

My question is: For those of us who have Broadcom chipsets, is there a different kext (or a different version of the same kext) that I might try downgrading?

I no longer have any files from Snow Leopard, so if there is a downgraded file to try, I would appreciate someone posting the file online and pasting a link here, so that I (and others) can try downloading and installing it.

I have 2 Snow Leopard kexts, one from my 13" 2011 Macbook Pro OS restore DVD and another one from a DMG of a retail 2009 Snow Leopard DVD. I haven't tried the 2009 Snow Leopard DVD's wifi kext but will when I get home. I'll see if I can find somewhere to upload them tonight.

Great.  Thanks.  You might try dropbox or hotfile if you can't find anywhere else to upload the kexts.  I look forward to giving them a try.

I have a late 2010 iMac with Netgear DGND3700 ADSL Router and since installing Lion have had no WiFi connection following wakeup from sleep. No other issues with WiFi and although this thread has provided several possible fixes and a great deal of discussion, to date, no solution.

Rather than wait for Apple to provide that WiFi solution there is a temporary fix which has worked with my hardware for the past month. If you are happy using Terminal then install SleepWatcher with the following sleep and wakeup actions:

echo '#!/bin/sh' >~/.sleep

echo '/usr/sbin/networksetup -setairportpower en1 off' >>~/.sleep

chmod +x ~/.sleep

echo '#!/bin/sh' >~/.wakeup

echo '/usr/sbin/networksetup -setairportpower en1 on' >>~/.wakeup

chmod +x ~/.wakeup

See the effects in your Console log. Works for me until Apple come up with the definitive solution.

Dhwalt:

Thanks for the suggestion.  Do you just paste the code into terminal and the rest will happen automatically?

If I decide to uninstall SleepWatcher in the future, how would I do that?  I'm reluctant to install something that I don't know how to uninstall.

OK, I haven't read all posts/threads, but here's what's happening to my MBAir:

Just bought it and it has, of course, Lion as its OS. In my house, there are three Macs: PowerBook 12", MacBook (Black) and the Air – they run Tiger, Leopard (or Snow, not sure) and Lion, respectively.

Mine (Lion) is the only one with wi-fi issues: strong signal, but pages won't load. When they do load, it's quite slow and unstable. HOWEVER, if I get closer to the access point, wi-fi works perfectly well (by close I mean 1 meter away lol).

Even my old 802.11g iPod touch works fine in my room – but the Air just won't. In other networks, it works fine – as far as I remember.

Does anybody here have a clue of what might be going on?! Has Apple released anything concerning that issue?

Thanks a lot!

Then I suggest to do so, to compare with your issues and eventually find a solution.

Best at all is to open your own question about your own problem -> https://discussions.apple.com/static/apple/tutorial/ask.html

Thanks Lupunus

ASUS:

Yeah, that's the one, ASUS RT-13N.

It is on FW 1.0.2.0, based on the site, this is the last one, most recent.

I've changed it's domain name to "local".

MAC

None of the files were found on the system.

Reeboted the system anyway.

The problem persists.

Any ideas why I did not find any of the files? I used spotlight to make sure I wasn't doing something wrong.

Anything else?

Thanks

Hello

To find these files you need to look in macintosh hd in finder, this is hidden in lion so here is a Link for finding it

http://www.ivanteoh.com/blog/2011/07/where-is-macintosh-hd-in-os-x-lion/

Hope this helps :-)

Also try disk utility, repair disk permissions

For Moskovit,

Download and unpack SleepWatcher 2.2.

There is an extensive ReadMe which covers the installation and uninstall.

You will need your admin password to use sudo from the Terminal.

Copy n paste individual lines followed by return into the Terminal.

Sleepwatcher installation for new users:

*below are single lines

sudo mkdir -p /usr/local/sbin /usr/local/share/man/man8

sudo cp ~/Desktop/sleepwatcher_2.2/sleepwatcher /usr/local/sbin

sudo cp ~/Desktop/sleepwatcher_2.2/sleepwatcher.8 /usr/local/share/man/man8

sudo cp ~/Desktop/sleepwatcher_2.2/config/de.bernhard-baehr.sleepwatcher-20compatibilit y.plist /Library/LaunchDaemons/de.bernhard-baehr.sleepwatcher.plist

sudo cp ~/Desktop/sleepwatcher_2.2/config/rc.* /etc

Simplest method to swap back to default WiFi is to drag the LaunchDaemon to trash i.e. de.bernhard-baehr.sleepwatcher.plist. Trashing will require your password. If you want to see the above files in the Finder then unhide the Library folder:

chflags nohidden ~/Library/

Not forgetting the sleep and wakeup actions from the original post are required.

For the user transparent when working other than a couple of pulses from the WiFi icon on wakeup.

Note this is not a permanent solution, nor is it optimal environmentally speaking... but it worked for me.

I have a 27' iMac from Oct 2010. No wifi issues under Snow Leopard but once I upgraded to Lion constant dropping of internet connections and having to find the network again. Very frustrating!

2 Days ago went into System Preferences - Energy Saver. Changes setting for Computer Sleep to NEVER.

Left Display Sleep at 3 mins. Unchecked 'Wake for network access'

So now only:

Put hard disk(s) to sleep when possible

Allow power button to put computer to sleep

Automatically reduce brightness before display goes to sleep

remain checked.

Have remained connected ever since.

Not very scientific and certainly not power saving... but until I have comfort that the issue is resolved its working for me.

Dwight.

Because you wont find them with Spotlight.
