I replaced the WA5210G on my house antennae with a CPE210. I also added a second CPE210 on a new outbuilding. That is working fine to provide internet to that building. However, I am having difficulty getting my older WA5210G's to work with the new AP on the house. The WA5210G's on other buildings are connected to IP cameras. They are both 2.4Ghz and I set the channel width to 20 on the CPE210 to match the WA5210G. Is there any other settings I need to change on either AP to get them to work together. I can connect directly to the WA5210G by LAN and see the CPE210, but from my house computer, I cannot see the WA5210G or the IP camera that is connected to it. If neccesary I will replace all the older AP's, but if I can get them to work as is it will save me some $. TIA for any ideas.

I suggest you look at WA5210G working channel and adjust CPE210 and WA5120G to the same channel.

Of course, align the two devices whenever possible. If we cannot see the WA5120G SSID on CPE210, it is likely to be the problem of WA5120G channel selection.
