Slow wifi Speed

Hi,

I've been using Tomato now for quite some time.

Never had any trouble but since 2 weeks my wifi speed is bad.

I've tried reflash older firmware -> no luck

After a 30-30-30 reset I still have Tomato firmware on my router -> is this normal?

I don't know how to solve this. Can someone please help me?

 

Thanx in advance

I had the same issue. wifi was very slow. wired was ok. Had to go back to DD-WRT.

Just tried again with Tomato.

Just tried again with Tomato. FIXED IT!

Under Advanced/Wireless, disable the WMM setting! I saw another post that mentioned it earlier, but, could not find the setting until now!

Working good so for on my v2.

Disabling WMM is not a good

Disabling WMM is not a good idea, its part of the N specification, without it - you'll be reduced to G speeds, but if being on G speeds is what you called 'FIXED' then please continue on without disruption...

haha. i should clarify.

haha. i should clarify. with this enabled, my wifi speeds (802.11n) were: 1Mb/s download, 5Mb/s upload, measured with speedtest.net

(And pings were erratic. 10ms, 10ms, 840ms, 10ms, 8ms, 500ms, etc.)

Wired connection as 38 down and 5 up.

With this DISABLED, wireless is now 30 down and 5 up. So, "fixed" may be the wrong word. "Workaround-enabled" may be better.

Something is def wrong there.

It may have something to do

It may have something to do with how you have your N selection as far as channel overlap/blocking selection amongst whether you have it set in HT20 or HT40, overlap is going to cause you to have slow speeds. As well as improper wireless security choices etc. The OP never lists the complete setup of what they got going here to know what may be the cause... but i can assure you, disabling WMM is not a good idea.

I don't use tomato so i'm not sure if i could say its an internal problem with tomato or not, but if it is, i would most likely suspect the wireless driver as the culprit. Tomato has a habit of incorporating newer broadcom wireless drivers without really testing them in a real world environment first. It seems their users see a higher version number and get some kind of fabulous placebo thinking because the number is higher its got to be better, which isn't always the case.
