Airport problem

I looked through the possible settings and tried changing net.inet.tcp.rfc3465 to zero since I thought the second command might've been a typo for that, but that didn't fix the problem either.

Sorry, that should have been rfc3465. 🙂

Sounds like it isn't any of the congestion control causing the problems. I'm out of ideas.

Gave both 3465 and 1323 a try and it didn't make any difference. Bandwidth was great for the first 3-5 meg on a decent download and then after that it would slow down to a stop. More often or not the wireless connection would then go down momentarily before coming back up and going through the same cycle.

Hi:

Same problem. I upgraded to 10.5 from 10.4.9. I cannot connect to a wireless network with WPA security that worked great before the upgrade. I can still connect to one of my neighbors unprotected wireless network.

I keep on loosing my Airport connection often. The only thing I can do is disconnect Airport and re-connect to restore contact. I have the same problem in iTunes with the Airport connected speakers. Apple should correct this urgently.

Same here renek.

I actually noticed this problem last night, thought it was my network - turns out its not! I'm so glad I found this thread.

Let's hope Apple does something about it ASAP. I'm sure there's got to be a work-around.

Add me to the list.

This is infuriating. I can't get a connection to last more than 10 minutes (often less) without having to tell the computer to turn it off and then on again. Other divices on the network are working fine.

I have a WDS (wierless distribution system) using a Belkin as my main router with 128 bit WEP security. An Airport Express and a second Belkin act as access points/relays.

Same problem with me.

But also this one: CPU activity at 50-90% due to SyncServer and DockSyncClient ( http://discussions.apple.com/thread.jspa?threadID=1198097&tstart=0)

just a quick question/pointer. do all of you who have slow wlan connections run an encrypted connection?

I'm - kinda - having the same problem, although a bit more severe variation.. I cannot connect to ANY wireless network that has wep encryption.. no "password", 40bit, 64bit or 128bit. it always results in "incompatible security" message. (my access points communication just fine with each other, as did this computer yesterday with Tiger...) My access points are 11b d-link (ap-700) and linksys (wap11). Unsecured works just fine (so I had to turn on MAC filtering which is a pain in the proverbial with many clients...).

I've the same problem with Leopard and my PowerBook G4 1,5 GHz BT 2.0!

Apple, fix it!

Ditto here. I get an "Incompatible security" message. Worked perfectly before under Tiger. What's up with this?

Same problem here on a PowerMac G5 with Leopard installed. No problems with Tiger. Our iMac and iBook with Tiger still work fine. Trying to connect to airport extreme and airport express configured with WDS & 128-bit WEP. Connection drops about every 5 minutes.

Totally unacceptable. FIX IT APPLE. Leopard is useless to me like this.

Have you tried using the Diagnostics button in the Network tab? I had serious Airport problems in the past on Leopard (if you enter a Manual IP and it doesn't work, Leopard refuses to FORGET IT! So if you try to use DHCP, it keeps giving you the wrong Manual IP. If you don't use Diagnostics it will never work again. Diagnostics fixed that, though.)

Let me know. I'm having serious problems (still) with web-browsing speed, but I did fix that particular issue.

I seem to have found a fix for my situation. I'm not sure how it'll help people without Airport base stations, however. I went into Airport Utility, disabled Interference Robustness, and set the multicast rate to 24 mbps. I haven't had any problems since then. I'm not sure which setting fixed it, or if it was the combination, but I don't want to screw with it to find out for fear that I'll break it again.
