Issues with wireless AP100c

Question

Long time lurker, first post and a beginner when it comes to more advance networking setups. I'm using this in a home lab for learning. Running XG18 
 Having 2 issues with my AP100c access points. The access point is literally 8 feet from my laptop. 
 
 Connection just drops. I'll be browsing the web and for whatever reason, I'll get request time out for a few seconds. The signal still reads high. I have tried 2 power adapters, network cables, and access points (I have 3). No problems with the port I am using when I am hardwired to the laptop. 
 Internal file transfer speed slow. I always show no less than 650mbps connection and the channels I have used have no interference. Max I ever see is around 11MB/s transfer. I am using 80mhz channel width and if I decrease this setting to 40mhz, I get around 5MB/s. Hard wired I get full bandwith, over 100MB/s, so it isn't a bad port. 
 
 Also, I have a AP that is not managed by Sophos, and I do not exhibit any outages when using wireless. 
 TIA for any help

 Thanks so much for your time. I finally figured out what was causing ALL my issues. I purchased new Cat6 cables 3 foot long and made sure they were POE compliant. Replaced the 2 cables that I used to connect the injector and the AP and I have not had a disconnect in over a day AND my speeds are significantly better. (+20MB/s). I sure wish there was a way to see into the AP for this type of issue, but I am thoroughly happy that I finally have this resolved!
