I noticed that several were getting same error on the 250's as well. Is this a known issue? Im on latest firmware.

I'm seeing a high CRC failure rate for both wifi0 (32%) and wifi1 (72%). That means that 32% of the wifi0 traffic and 72% of the wifi1 traffic is too damaged to read and had to be resent at least once (likely more than once) before the receiving radio could read the packets and move on to the next. CRC failures in particular are usually caused by environmental factors. Could you send me pictures of a few problematic APs so I can check for environmental factors that may be interfering with your signal?</P> Tue, 03 Mar 2020 03:32:43 GMT https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87030#M11350 samantha_lynn 2020-03-03T03:32:43Z https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87031#M11351 <P>I am only getting this on the 2 new 305c's. They are the only 2 in this building. When you say send pictures are you meaning literally taking a picture of the WAP where its installed?</P> Tue, 03 Mar 2020 03:35:48 GMT https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87031#M11351 jharrell 2020-03-03T03:35:48Z https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87032#M11352 <P>Right, with as much of the area around the AP showing as possible. We want to rule out mainly metal, glass, water, or dense obstacles between the APs and the client device area. </P> Tue, 03 Mar 2020 03:45:50 GMT https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87032#M11352 samantha_lynn 2020-03-03T03:45:50Z https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87033#M11353 There are quite a few windows in both rooms.

The first picture doesn't show any issues. The second pictures shows an AP sitting on a table facing up, a better placement for that AP would be facing where the client devices will be. That said, given the heavy rate of CRC failures you're seeing an not a lot to explain that in these pictures, I'd recommend opening a support case so they can do a deeper dive in to your data with you. </P> Fri, 06 Mar 2020 03:19:51 GMT https://community.extremenetworks.com/t5/aerohive-migrated-content/i-just-put-in-2-ap305c-s-in-my-building-keep-getting-wifi0-a/m-p/87034#M11354 samantha_lynn 2020-03-06T03:19:51Z
