Hello,

I work for a sign company that occasionally does LED signs. We did a sign not to long ago for a YMCA here in town. The sign is about 500ft or so from the modem and the company that provided the LED sign recommended we use 2 CPE210's to get the wifi to extend far enough out to the sign. This is so they can use an online editor to change the images at will without needing us to do much.

The problem is that in the last 3 months They've had an issue with the sign not connecting to the wifi. When i check the extenders they're on and the wifi signals appear on my devices but i can't seem to get the chrome box inside the sign to connect even though its hardwired to one of the CPE210's. I don't know enough about the TP-link's to trouble shoot them and the company that helped me install it is practically MIA at all times. Does anyone here have any detailed trouble shooting steps that i can take to get these to work? They obviously do work, they worked for almost a year straight and then all of a sudden started having issues. The first time the problem just seemed to resolve by itself. this time however that is not the case.

I do not know the hardware version of the cpe210's nor do i know how to update them. I tried to get in touch with Tech Support through TP-link the other day and sat on hold for 2 hours just be to be hung up, probably was a mistake on their part but still was very unhelpful and frustrating for me since i have to try and solve this issue for the client when i don't really know what i'm doing in the first place.

Any advice would be greatly appreciated, thank you.
