Re: WLAN Problem since 2.0.1.358

My playbook is working again with my wi-fi at home - what was the fix - turning off the N band on the router.

I simply removed N band from the 2.4 side of the router. then tried to connect and instant perfect access again.

Whatever the issue is with the .358 update it is related to the N band.

Re: WLAN Problem since 2.0.1.358

How to fix wifi problems --- step by step.

 

(1) update your router's firmware

(2) use the most basic configuration first --- G only, WPA2/AES

(3) N-only, WPA2/AES 

(4) DD-WRT users --- set ACK Timing to auto (i.e. for Atheros chipset, it is 0).

(5)  Turn WMM settings on and off to see if there is a problem.

Re: WLAN Problem since 2.0.1.358

Hello Janetsa,

 

I believe you may have an error in step 2 (at least with some router manufacturers). For G only mode using WPA2 has a cipher type of TKIP and not AES. If the cipher type is set to AES, then wireless N mode will occur. Otherwise it bumps it down to G speeds. I came to this conclusion from trial and error as well as verification from Wikipedia:

 

TKIP (Temporal Key Integrity Protocol)  The RC4 stream cipher is used with a 128-bit per-packet key, meaning that it dynamically generates a new key for each packet. Used by WPA. CCMP  An AES-based encryption mechanism that is stronger than TKIP. Sometimes referred to as AES instead of CCMP. Used by WPA2. With some hardware manufacturers, AES-CCMP must be set to enable 802.11n high bitrate schemes.[21] Otherwise, the data rate will not exceed 54 Mbit/s. (which is G speeds)
Full Wikipedia article (boring read).

Re: WLAN Problem since 2.0.1.358

I have found a solution that enables me to get my Playbook and all other devices in my house to get on ONE wireless network connecting at N speeds INCLUDING the Playbook thanks to two members of the forums from www.Crackberry.com. (Major thanks goes to members Eli.Bret and PatrickMJS for their help!) My router is a D-Link 825 and I have attached settings images to help you. It turns out the Channel Width setting had to be changed to 20 MHz from 20/40 MHz or just 40 MHz. If I did not do this I would have problems with the Playbook. Both Eli.Bret and PatrickMJS both had this setting changed to 20 MHz. I did NOT initially. It was set to 20/40 MHz initially.

 

In short, here are the settings for the 2.4 GHz radio:

802.11 Mode: Mixed 802.11 G and 802.11 N

Enable Auto Channel Scan

Channel Width: 20 MHz

Wireless Security Mode: WPA-Personal

WPA Mode: WPA2 Only (the most secure)

Cipher: AES (the strongest type)

 

Here are the settings for the 5 GHz radio:

802.11 Mode: 802.11 N Only

Enable Auto Channel Scan

Channel Width: 20 MHz

Wireless Security Mode: WPA-Personal

WPA Mode: WPA2 Only (the most secure)

Cipher: AES (the strongest type)

 

Use the SAME SSID name too for both radios.

 

 

Anyhow, here is a copy/paste of my last post over there that will explain things better:

 

 

I have managed to get everything online on the SAME network now at N speeds on the D-link 825. One of my desktops gets 144 Mbps. My laptop only gets 65 Mbps though but the Playbook now gets 65 Mbps!!! That's up from 54 Mbps on G speeds.

The problem seemed to be the channel width setting. It was really the only different setting I had to change. If I set it to Auto 20/40 MHz, it would kill the Playbook connection rate. I mean web pages wouldn't ever fully load and the blue status bar would never reach the end of the interface. It would just stall out. Didn't matter which webpage I loaded either.

Now, the laptop took a speed hit by doing this setting change though. It went from 144 Mbps down to 65 Mbps and would not go any higher with this channel width change unless I turned it to 40 MHz or to 20/40 MHz. Again, if I did this, the Playbook connection stopped...

I also didn't touch any other default setting with the router. WMM remained enabled and Short GI also remained enabled.
