Simply make your wireless router/basestation B only.
I'm using airport express, so I just use airport admin in the utlities and alter the setting in that application...
Rockin Airport
Im using a MBP 2.0 and my airport signal rocks, am in a second floor, and my base (Linksys WRT54g) is in the 1st, I have FULL signal, all the time, and full download speed. (I use the base in b mode to get more signal)
Dont know about the problem yet, knocking wood!

I hear ya. I don't want to jack your thread so I won't. But suffice to say I love this thing and am super happy that I finally switched from Windows, but there are a couple of little quirks that bust my ass a bit. Stuff I'd just live with on Windows but expected, after hearing all the praise, never to deal with on a Mac. Okay, enough-- I've got other threads out there for that stuff.
I'm going to keep my eyes open in here though looking for the airport solution-- whether I"m using it now or not. You would THINK, if Apple prides itself on being so superior, that they'd identify and do a recall or send an email saying "bring it in for a new card." I don't know.
my macbook is having no wireless speed issues at all.
I have tried it with my school's wireless network, as well as my own airport express (g) network.

Read more of the thread.
Some modes are more reliable than others and some firmwares suffer problems more so than others. The fact that you are in b mode changes some of the problems as putting the router in b mode was one of the workaround solutions.
consistent but slow
Well, here's a new wrinkle....
First off, I've got the 0.1.16 firmware, and I see nice consistent ping times, mostly 2-3 ms, with a few around 5. Nothing to really worry about. Signal strength seems to be OK, although I think it may drop and then reconnect occasionally. This is in a dual core mini, using an Airport Express.
The problem I'm having is transfer speeds. I've tested my transfer speed by serving a large file via web sharing, and downloading with Firefox on the other end. Going from an old TiBook with a G card to a Dell laptop, I get 1500-1700 KB/s. Not too bad. From the TiBook to the mini, it's 300-400 KB/s. Going back the other way, from the mini to either the TiBook or the Dell, the best I can get is 200-300 KB/s. These tests were done with the Dell sitting right next to the mini. I've tried doing the exact same transfer via a wired connection, and it's super fast in any direction. So it's not a general problem with the mini -- definitely Airport related.
I get the same behavior with the Airport Express set to either B/G mode or G only. I didn't try B only mode because I'm not interested in running at B speeds!
I find this interesting because if I only cared about my connection speed to the internet, and only tested it that way, I'd have nothing to complain about because the max d/l speed I'm getting on the mini is about the max I ever see come through my cable modem. I think my cable modem lets me upload at something less than 200 KB/s too. At these speeds, B is good enough for me. But I want G speeds for traffic within the LAN, and that's what I'm not getting. I think most people do not run this kind of test -- I am very curious about how many people have this problem and just don't know it (and/or don't care).
Anyway, I opened a case with AppleCare and am taking the mini over to my local Apple Store right now to see if they can determine what the problem might be. I'll follow up when I find out anything.

Can't Find Remote Speakers on Airport Express on Macbook Pro.
I'm having a problem with my itunes finding my remote speakers on my macbook pro using my airport express. When I unplug my LAN cable from the wall in my dorm room (T1), the speakers will show up, but not with the LAN cable plugged in. When I'm at home and use my cable modem/router setup plugged into my airport express, the speakers show up. Weird stuff. The dorm/airport setup worked fine on my old 12" powerbook. Also, a lot of the time my comptuer won't even recognize my airport express even when the light on the airport is green. Apple said they'd replace the airport and that I could just go to any apple store to swap out. Of course, when I go to the apple store, they don't have any in stock.

A quick followup on the message I posted yesterday.... It looks like my mini's Airport is working fine! Well, kinda.
It was impossible to get any 2 machines to communicate at more than 200 KB/s at the Apple Store. Not sure why and don't care. So we set up a computer-to-computer network between the mini and a G4 PB. This gave us transfer speeds of about 3.3 MB/s in either direction, with either machine acting as the creator of the network. I was very happy to see good transfer speed in and out of the mini. That tells me that it's not a hardware problem, and it's probably not a firmware problem. Hopefully it's just some configuration problem, and not a software problem that Apple needs to fix. Either way, it doesn't really belong in this thread!
Thanks for all the info that others have posted about this issue!
Cheers,
Matt

My symptoms were persistent, even though I had a brief moment of speed after switching to WPA2 only. Did some more reading, and at MacFixit they pointed here:

Eureka, this did it for me. Pings are normal again and no disconnects. This is suggested as a TEMPORARY fix, just read on the page. Hope it helps.

My MBP has no problems on my wireless network (Netgear WPN824). I get great signal everywhere in my house, the base station is in my room. On the other hand, both Windows desktops in my house don't seem to want to maintain a connection (I have Netgear cards installed on both of them). Both of them seem to drop the network connection after any real period of inactivity, this is more annoying with my parents' computer because I don't use my desktop anymore. What bothers me most is that I set the Anti-Virus software to update itself everyday, but without a network connection I have to do it manually, it's like being on dial-up all over again. I wish Microsoft could figure out how to handle WiFi connections.

I just bought the iMac intel 20" and airport express yesterday. Set up airport without a hitch with my "old" mac (iMac Flat panel) - and today wifey is zipping away through here blogospheres at a full ISP-given rate. Hubby, on the other hand, is clunking away at intermittent rates (if at all) with anything at all to do with an airport connection to anything (airTunes, computer-to-computer connections, internet).
I've spent a good half hour reading this forum, and have not much to add - but perhaps one thing: when trying to send music to the 'remote speakers' from iTunes, I noticed that it would go in 'packets' - play a few seconds, stop, play again - and sometimes the last 'packet' of music would play even after I hit the stop button. In this it seems that somehow, somewhere, data is being accumulated before it is sent to the network...
Anyhow, godspeed and let's hope for a solution sometime soon. Hubby's got work to do.

No mate you've got the same problem, same firmware as me & same airport express
All we can do is hope 10.4.6 comes out very shortly and it has solved it, otherwse I'll be pissed....

I have same card so im thinking its a problem with my router. My ping tests show norm fuction but my reception is constantly fluctuating and if taxed(WOW) drops off every 15 min.
Well, that ACK fix may have worked for a little while but the problem persists. Seems like if I rin PING 10.0.1.1 and just sit and watch, everything is normal with all pings <1ms. If I start an application, open a window, use the dock or whatever, PING goes to 200+ and fluctuates.
Activity related? But I don't see a pattern....
Activity related? But I don't see a pattern....
Possible fix and some good news (?)
First the possible fix:
I have experienced exactly the same problems as described in this thread. Ping fluctuates from <1 ms up to >200 ms and then down again. I have compared it with Linux boxes, XP boxes a new Mini Mac and an old G4 machine, they ran perfectly. I have tried 3 different setups - 2 access points; D-link DWL 2100-AP and Netgear WG 302 as well as Netgear Router WPN824 - same problem with the iMac Intel Core Duo. However I tried with an Airport Express as well (Firmware 6.3) as an accesspoint and that solved my problem!!! The iMac runs great, no problem with the pings any more.
Now some other good news - I don´t know if this will affect the iMac... I have a Mac Mini Intel as well -the bluetooth is lousy and there are 2 different firmwares on the delivered macj´hines and one of them has problem with Airport. I just talked with a service center here in Sweden and they said thet Apple is aware of the problem, that they shouldn´t try to repair any more machines and that a fix for Airport and Bluetooth is beeing released next week. I am writing this because hopefully a fix for the Airport might fix the iMac's problem as well - i mean not everyone has a Airport Express lying around and Apple should be able to communicate with other vendors equipment as well.

Good news about the possible updates, 'cos I ain't buying an Airport Express!
Aside from the ping problem I also had the disconnecting problem both "randomly" and after waking from a sleep. I fiddled round with the router and found that, by default, a framebursting mode was enabled - which was only compatible with certain wifi adapters. So I turned it off.
While I still have my ping problem, the connection is a lot more stable. In fact, since I turned it off 3 days ago I've not had the connection problems.

Have you tried the new firmware/driver ktext from the discussion forums at apple? It apparently resolved all the LEAP/PEAP problems, so it would be interesting to see if it resolved these problems as well.
