Hi @DPE1983
Thanks for your post!
As the WiFi signal is of sufficient strength, the amount of transmission errors I see indicate a probable source of interference either near the Connect, or near the Access Point the Connect is using. In addition, I see one AP on channel 5 and another on channel 6 - this is worse than having both on the same channel, as when two APs share a channel, they will at least co-ordinate their transmissions. With them being on separate but overlapping channels, they will both transmit without regard for the other, and thus interfere. Please place the AP on channel 5 on to channel 1 or 11 instead (or 6, but 1 or 11 will probably be better), and keep any WiFi devices at least 1m away from the Connect and APs (including each other).
If these steps do not solve the issue, please let me know as there are more things to try, and for other reasons.
I hope this helps.
