bandwidth test over 3rd party wireless

Sat Jan 01, 2011 8:40 pm

I use MT routers in various places in my networks.
In areas where they are just routers (no wireless cards), when I run bandwidth test between two 493AH routers (both on V4.5) that are connected to the same HP switch, the speeds look great. But in 3 different places when I run across either a Ubnt link (100% connection quality) or a Motorola PTP800 link (100x100 full duplex) I get speeds that are around 15-18Mbps each direction.

Is there something that keeps the bandwidth tool from working correctly when going across a 3rd party wireless network?
I see the same issue with the PC based btest tool.

Its most likely that those links can ONLY do those speeds - despite higher data rates. We see this as well with MT behind UBNT links in bridge mode...

yeah, but it also does it on the Motorola Licensed 100x100 full duplex link.
And I know the link supports >15-18Mbps data because at peak times, I see around 25-30Mbps customer traffic.

What is the MTU of the links? Perhaps the btest packet size is too big and getting fragmented?

What speed RB are you using to test? Yuo could be maxing out the RB too

Tried MTU of 1500 and 1460. No change.
Testing to MT493AH.
From the PC to the local MT493AH I get around 78-80Mbps each direction.
To the remote MT493AH on the other side of the Motorola licensed MW link (100x100 full duplex) I get about 18x16Mbps.
I know its not the link as the customer traffic runs in the 20Mbps range.

Very perplexing...........

Just found a queue on the other side that was limiting the bandwidth.
Its good when I turn the queue off............how embarrassing!!.
