I got some LAN network to extend and I cannot drill walls. It is quite big school building. I decide to extend it using HomePlug AV, Powerline adapters. I have two sets of: ASUS PL-N12 300Mbps adapters and one set ASUS PLAC56 AV2 1200 adapters I need to make 3 WIFI access points using those adapters.
I noticed that the more adapters in electrical network the more problems with network initialization and network interrupts from time to time. I noticed also that input adapters cannot be in the same electrical plug.
Right now I have two sets working on different floors, but it seems to be not solid solution (initialization problem). And I need to add third one on the one of floor that I have adapters already. Third one adds even more uncertainty to my solution.
How to make those adapters work together? Is there any other solution that doesn't require wall drilling?
