I think this did the trick!! thanks!! initially I changed it and it went back to 2000..did it again and made sure it stayed in 0 and it worked!! THANKS..well...it worked for now..kind of not trusting of its stability..but thanks!04-26-12 03:07 PMLike 0 -
Atheros/ath wireless settings - DD-WRT Wiki
DD-WRT Forum :: View topic - ack timing - Lets clear this up
Which means that there is NOTHING wrong on the RIM's side of programming.04-26-12 03:23 PMLike 0 -
So here are my settings:
N-Only (2.4 GHz)
Channel Width Full 20 MHz
ACK Timing 0
That did the trick. Any other combination didnt work. Now, I am hoping that when I get home and I change the settings on my router (which is the same), that it works...So..I will post later what happens at home.
Thanks!!04-26-12 03:26 PMLike 0 - I did reboot when I changed it to N-only with 20 MHz..However, I will retry these when I get home..will let you know..but I think what Pynk Floyd suggested was necessary..my default was 200004-26-12 03:30 PMLike 0

- who knows right? now that I am playing with this new version, I hardly notice the changes/additions but it broke my wifi. Is like, dont break it if its not broken.04-26-12 03:48 PMLike 0
- Hi guys,
This is my set-up:
Playbook with 2.0.1.358
Netgear WNDR3700 with 14896 f/w
I encountered the same wifi connection problem as many described in this thread after the 2.0.1.358 update. As some have suggested to update the router firmware, I went ahead and updatd te WNDR3700 to 18777 firmware. This seemed to solve the problem. The 2.4 GHz connected well with stock settings, the 5GHz seemed to struggled for a bit (no clear reason why yet, will play with this for a bit). So, if anyone who seems to get stuck with this problem, update your router firmware!

I did only needed to change my router to N-Only. I saved the settings, then I changed my channel to 20MhZ. I saved the settings and rebooted my router. No need to change the ACK timing. Bad news, the connection lasted about 5 minutes..Also one of my laptops cant connect to the router when is N-Only. That laptop is pretty much new.04-27-12 12:03 PMLike 0

**UPDATE**
CHANGING THE Sensitivity Range (ACK Timing) to 0 (default 2000) did work..
So all in all, these are the steps that worked for me:
1. Changed Wireless Network Mode from Mixed to N-Only 2.4Ghz
2. Saved Settings
3. Changed Channel Width to 20MhZ
4. Saved Settings
5. Changed ACK Timing to 0
6. Saved settings
7. Rebooted router.
Its still on.04-27-12 12:08 PMLike 0 - I have 2 of the same laptop. One with windows 7, the other with Linux. The windows 7 cant connect, Linux can...Same wifi chip...

It means that the default router setting is to blame --- nothing to do with RIM.
Now that you managed to pinpoint the source of the problem, then you can start to optimize your router's other settings to suit your needs -- one step at a time. For example, if you have older laptops which has only 802.11g --- now is the time to change your router to G/N mixed. If that setting works for you for a couple of days, then you can optimize from 20 MHz channel to auto channel.

www.dd-wrt.com | Unleash Your Router
The main use for DD-WRT is (1) official firmwares often can't handle too many connections which kills bittorrent users and (2) end users want to bridge 2 wifi routers together.
But I find that because it is an open source project --- they are basically creating a frankenstein firmware for their TWO needs. They don't touch or improve the actual wifi radio codes --- since I don't torrent nor I bridge multiple wifi routers together, I went back to official firmware because the official firmware has newer radio codes.04-27-12 12:52 PMLike 0 -
Toshiba Wireless Connection Portal:
Reboot your laptop and then see if it connects. A new laptop with a known N wifi radio can't connect to a a N-only router (with the most basic settings) --- then it's the laptop problem.

I think something must have changed in the last update, like I said, this used to work wonders without ever disconnecting. I had ACK Timing to 2000 which in my router is the default and I also had channel width @ 40MhZ. Is really odd that all of the sudden after the update its just a no go.
ONE step at a time. You didn't even know which particular setting is the problem --- maybe it had nothing to do with 40 MHz channel. My list is to isolate the problem, one step at a time. Now that you isolated that problem to be the ACK Timing default setting is wrong, then you can play with other settings.04-27-12 01:47 PMLike 0 - I have 2 of the same laptop.

I'm running N-Only on the 5 GHz band with Turbo (40 MHz). I've noticed that the last 2 DD-WRT releases have required me to set the channel manually or else it wouldn't broadcast anything.
As for your Windows laptop, there are some additional settings in the adapter properties. Go to Control Panel -> Device Manager -> expand your Network Adapters and right click on your wifi card and then hit Properties.
Under the Advanced tab, check your settings. There are a lot of N settings in there. Keep in mind that "WMM Enabled" must be set in "Ad Hoc QoS Mode" for N to get its full thoroughput. Hopefully that fixes your laptop issue?
Here's a detailed wiki on it:

My router is set to N only and everything else on my network hits max thoroughput. If eeeeeverything else on my network is A-ok and the Playbook is not, it leads me to believe that it's a Playbook issue.
Even with the timing change, the Playbook takes a while to load a web page. At least the connection isn't dropped...as often. (As I type, I still can't fully load the Yahoo page that's bookmarked by default.)Last edited by PynkFloydd; 04-27-12 at 02:00 PM.

You could be using some ancient draft n radio codes even though you downloaded the latest DD-WRT firmware --- that's the reason I went back to official stock firmware.04-27-12 02:28 PMLike 0
- Auto channel width --- not necessarily 40 MHz.

Are you saying that you have wifi problems with ACK Timing at 0 and channel width set to 40 MHz?
Do you live in a high rise apartment where there are a zillion different wifi networks? If that is the case, not a good place in general to set your wifi network to 40 MHz.04-27-12 06:07 PMLike 0
