Adding A 802.11b To 802.11g
« on: May 24, 2006, 04:58:10 am »
Hello. I read here and there all the problems people have with their zaurus and wifi 802.11b cards that connect badly to access points when in mixed b/G mode. They fix the problem by forcing b-mode only.
As I have an 802.11g AP (linksys WRT54g) that I want to keep as g-mode since I use it at max speed, I would want to know if it would be possible to add a 802.11b access point that would be connected to it, that would be dedicated to b-mode connections only, so that accessing my internal network with the zaurus with a 802.11b wifi card (like a planex cf11x or ambicom wl1100c for ex.) would not prevent from using the main access point as 802.11g.

PS : I ask this because I plan to buy a wifi card but I don't want to be bothered by such problems and am ready to buy a 802.11b AP if it can help me.

One easy way is it set the AP connect to the specific ESSID and/or set it to only look on the specific channel the 802.11b AP is set to...

miloo: read about WDS (Wireless Distribution System) where few AP work with same essid and settings - you will make one G-only and second B-only.

Miloo:
The Linksys WCF54G Wireless-G CompactFlash card is hoped to be working with OpenZaurus in the near future (see this thread)

Thanks again, Hrw!

I do have two AP (one g and one .  I have no problems with any of my Zs connecting to the b.  A g card would be cool......

The problem with WDS is it works by making both routers act as repeaters.  Any traffic one receives, it sends to the other.  Having B clients degrades performance on a G network, so performance will always be degraded because the two routers are always going to be repeating to each other.  This rather defeats the original poster's purpose of having a seperate network so as not to degrade the G network's speed.

You'd want to link both AP's to a wired network instead, and make sure they are using different frequencies (and SSIDs) so they don't interfere with each other.

Thank you for all answers. It seems that's not so obvious ...

InSearchOf : so you wire the 802.11b AP to the 802.11g, and using a different ESSID for the 802.11b, the zaurus should connect to it, and thus be connected to the network without having effect on the speed of the 802.11g AP ? Is that true ?

just a little tidbit I found at toms hardware

toms hardware as tips on this

You'll need to do the following to set this up:
- Use only channels 1, 6, or 11 and set the 11b and 11g APs to different channels.
- Disable 11b protection on the 11g-only AP (this is frequently called 11g-only mode)
- Set each AP to a different SSID (not essential, but helps for troubleshooting purposes)
