Horrible Mixed mode N speeds
« on: August 27, 2010, 02:24:34 AM »

Hello all, just bought a 655 to replace a wbr 2310.

heres the skinny.

currently only have 1 N device (more to come in the future I hope) and 5 G device (not usually all on at once)  any way, in mixed mode, either B/G/N or G/N my N card, Linksys WUSB 300N, connects at awful speeds, a mere 13mbps.  far slower than G.  My G devices connect from 38mps-54mps depending on position in the house.

If in just N mode, I easily and reliably get full 300mbps on the N card.

If in G only mode (my current setting) the G devices work normally, just the same as in mixed, but the N card connects at a stable 54mbps.

Any thoughts to whats going on?

I feel i have tried every setting combination here.


20/40 is set to auto, but have tried stragiht 20.

running WPA2 only, AES

I have my wifi in hidden mode, dissabled SSID

QOs tried both on and off

I have an A4 which i upgraded to the latest 1.3 firware, then down graded to 1.21 then back again.  nothing changed there.

its always the same situation.  reguardless of other settings, if i just change the mode and nothing else i get those results.  and what is strangest to me is the 13mbps in mixed mode for the N card.  why slower than G?  and in G it max's out?  I can understand in N only mode that it would work, as there are no other competing signals.

but seriously 13mbps? I am sure you can see why i run G only mode now.  But if thats the case i wasted too much money going for the N router, and that makes me made, only reason i bought it was for mixed mode.  and i am a realist, i dont expect to get the full 300 in mixed, but i woudl like to be in the 100 neighborhood, and i think that is reasonable.

I have the latest card drivers and have tried forcing the settings on the card itself for N netorks.  I have th options but it makes no difference. all my machines run Win 7 pro.  and i think thats about all the info i have right now.

thank you for your time, and please help if you can.  I am open to all suggestions.

Try setting the RTS threshold to 2347 and use the windows wireless manager, not the linksys'

alrighty, i gave that RTS setting a try and that made no differnce.  I woul actually say it made it a bit worse on the G devices.

But thanks to you, you had me poking around in the advanced wifi section and noticed the "extra wireless protection option" and i looked that up, and it turns out i am suposed to turn that off if having issues in mixed mode.  and i did and now its working better.

however a couple of things.  the N isnt overly reliably fast.  it mostly fluctuates from 80-108mbps which is prob about right.  but then other times its back to 54.  My pings are good however.  and my G devices still perform properly.

lastly i noticed on my N card the signal dorpped.  in G only mode i was seeing 97-100% signal  now in in  G/N mixed mode it is 67%


so any thoughts to making it more reliably fast? and any theries on the signal drop??

thanks for all the help, i am currently much better off than i was before.
