Hints and Tips for Linksys WRT54G

If you're noticing some strange things happening with your traffic on a WRT, take a look here.

Predictable lost pings

If you're running a ping, and you've noticed that every nth ping (or group of pings) gets lost, try this. This will work for clients (ap=0)

wl lrl 100
wl srl 100
wl roam_trigger -100

Stick these in a startup script somewhere so they get executed every time the WRT boots. Basically, this stops your AP from scanning for stronger signal AP's with the same SSID. During the scan, it stops communicating with the AP that it was using, which causes ping spikes and iffy things.

Low throughput

If you have a very high signal strength (RSSI above 80) and you're connecting at a respectable rate (24mbps and above), but you're still not getting what you've expected.

First, take your rate (wl rate) and divide by 2. You will NEVER get more that this, so stop now.. its a lost cause.

Also, make sure you're working in the correct quantities (8 Bits = 1 Byte)

90% of the time, the problem is your noise level. And most of the time, you're causing your own noise because you've pushed your txpwr up too much!

wl txpwr 80

Put this in a startup script, make sure it gets executed before your wireless device tries to associate.
