5.150-5.250GHz
5.250-5.350GHz (Support Dynamic Frequency Selection)
5.470-5.725GHz (Support Dynamic Frequency Selection)
5.725-5.825GHz

You are on OpenWRT also.

Yes I am, but for my personal use I never had or ever flash a CPE.
5210 still today is a very popular one, and with the UBNT flash became even more popular, I did more than 10 for a friend that is in WISP business
7210 was ok but not as popular as 5210, today 7210 with the Beta FW, Rocks, deployed one for a cousin, more than a month ago, haven't hear a complaint.
7510 never wanted one, and if by some way I ever one had , it would had been flashed DD-WRT
Today with line Pharos CPE210/510, best thing Tp-Link has come out with.
I use OpenWrt in routers, homes here in Acapulco Mexico have lot of cement and steel, and in the crowded and competed 2.4 Ghz band Cron, is a need

No,the problem of DFS in OpenWRT is that i can't find my ISP AP,because my ISP AP uses the DFS channels.That's why i need the DFS channels in OpenWRT

Thank you for the answer, your ISP is using DFS for a reason, I suppose.

You are right at the point " your ISP is using DFS for a reason".
