Low Connection speed (11n + R52Hn + RB800)

Wed Mar 10, 2010 2:17 am

G'Day,

I have just purchased my first RB, and so far, its working great - the only issue is the WIFI connection speed that clients are seeing. The highest speed that anyone can seem to connect at is 130mbs. The test client system actually has a R52n in it, but have also tested with ASUS systems and a a belkin wifi router - so I know the client systems can connect at 300mbs - and the specs for the R52Hn say I should be able to achieve this setup.

If someone could please have a look over this config? With luck im just missing something simple. I have tried this at 5GHz N only, 2.4 N only and every other combination...

With 1 antenna is almost the top speed you could see.

U use 1 or 2 antenas?

G'Day, Thanks for your reply. Currently running with 2 7dbi indoor omni's. Chains are set to 0 and 1 for both RX and TX. Last night I had a play around and changed the frequency again (running on 2412 now), also disabled WMM support (although it is still ticked in the client info under the registration tab). It does seem to have improved performance a bit, but the client systems arnt connecting at any faster rate.

Has anyone with a similar setup (R52n/Hn's) had client systems connected at 300? What kinda of signal strengths are people seeing for their clients? - we are talking hotspot or WLAN setups here, not long range links.

Thanks again,

Jake

With a quick look the config looks ok, and just saw that you're working with 2 omnis.

Can you try just with just one chain enabled? Do you see any difference in speed or does it stay the same?

Tried it with just a single chain... no difference... if anything speed dropped.

The funny thing is, despite windows staying locked at 130mb, winbox will jump put to the mid 200's... Im guessing it might have something to do with the advertised guard interval? it there a way to set the GI to 400ns and force the 40MHz chan? Additionally does anyone know if there are any hardware restrictions on frequency selection for the control channel in order to use the above or bellow HT extension aka 40MHz channel? - Im thinking I might also be sellecting the wrong frequency and hence a full 40MHz channel is not available.

I have attached a pic of the windows registration as well as the winbox client registration window.

Thanks again.

Jake
