Strange Strange Wireless Issue

I have the oddest problem.

I have a mixed environment of 420's and the new MSM422's. For a couple of months I have had no issues at all.

But now, starting friday, my MSM422's have gone crazy.

If i plug them into the switch, they work perfect. They ping, when your connected to it you can ping, all perfect. As soon as they are connected via a cat 5e or 6 in the wall, the pings go from 1 (direct to switch) to 200 or 1000. They are slow, unresponsive and basically useless.

I can't find any problems aywhere in the configs. I have reset config to base, and reconfigured and it makes no difference.

The 420's work fine!!! Does anyone have any ideas?

Need some help here. Thanks

P.S. Wireshark comes up clean too.

Re: Strange Strange Wireless Issue

look like your fixed cabling is faulty.
maybe the lines from a pair are mixed.
If so you do get a 1-on-1 connection when wmeasuring this cable, but don't get the advantage of twisted pair so it picks up too much interference.

the msm420 has a auto-sensing 10/100 port the msm422 auto-sensing 10/100/1000.

also check if your cabling is 8-wire not 4-wire. for 1000 mbit 8-wire connections is preferred.
