you have a cable problem and/or you have an FM station nearby that is bleeding onto the ethernet run.
we always use shielded cable at the towers with a wbmfg surge protector (usually gige-apc-hv) at the bottom. you should see zero CRC errors...anything besides zero means you have a problem to fix. you can also try going to 100 half duplex or 10 Full or half and see if the errors stop. Right now I have 3 APs set to 100 half because there is an FM station (98.6...thanks toby keith ;-) bleeding RF onto the ethernet runs. we ran out of time this summer to run them in shielded liquidtight conduit. -sean On Thu, Nov 20, 2014 at 10:24 AM, Craig Schmaderer via Af <af@afmug.com> wrote: > This is a radio that has been up for 93 days, it is very heavy on > traffic, would you say there is an issue with this radio?
