RE: [smartBridges] AirBridges and Hubs/Switches.

[Kevin Summers]

Ok gang. I'm stuck again. I ordered $300 worth of

managed switches and just got back from replacing

the switch points along the network where the SB

equipment has to plug in with several other devices.

 

First, the switch auto detected 10 mbit just fine,

then I had to force Half Duplex. As soon as I did

it gave the same results as the 10 mbit hub that

I tried. MASSIVE amounts of collisions. I let it go

back to Full Duplex, and everything is ok.

 

So what is the deal? Are they 10Mbit Half or Full

Duplex on the SB gear?

 

I'm waiting to hear from some customers whether or

not this has improved things any. If it hasn't, I'm

at a loss for what is wrong.

Thanks. That's pretty much what I was afraid we were

going to have to do.

We were having the same problem. Our AP's were sitting behind Canopy SMs
and had a Lynksys switch in between the two. The switch was showing collisions
almost continuously.

Solution?

We put in Cisco 1500 series managed switches. I can't tell you how much they are
as we were diggin in the back room and found them in a corner. Look on ebay.
The nice thing is you can hard code the interface speeds.

After swapping out the switches, thru put tripled and dropped packets disappeared.

Can someone recommend an easy to find, and relatively

I've tracked down the problem of our speed decrease as
being the switches we are using. I've now tried 3 different
types of hub and switch with the same (or worse) results.
 
Basically what I did was plug the laptop into the hub/switch
with nothing else plugged into it but the radio. Then did a
speed test. The result was between 450-600Kbps.
 
I pulled the hub/switch and plugged the radio directly into
my laptop which has an auto sense 10/100mbit Linksys USB
Ethernet adapter, and did the speed test. The results were
between 900-1000Kbps.
 
A list of known compatible switches or hubs that don't
compromise the throughput would be great.
 
Thanks.
