Troubleshooting WAP Crashes

I live in a two floor dormitory-style building with about 25 other people and I routinely help out with Internet connectivity. Our speed is 50 Mb/s down and 10 Mb/s up. One of the WAPs in the network routinely crashes, or so I believe. When this happens, I sometimes am able to connect to another WAP in order to find out what happened. The device does not respond when trying to access the http admin panel. Attempting to use telnet yields nothing as well. It also does not respond to pings. I am forced to power cycle the device every time it stops responding in order to get it functioning again. This can happen up to 3 times per day.

All 4 routers being used are Linksys E1200 v2 devices. There is only 1 gateway which is the only one with DHCP enabled. The rest have DHCP disabled. All routers have DD-WRT v24-sp2 mega installed. When setting up the 3 WAPs, I followed this guide. The 2 WAPs do sometimes not respond as well, but it happens entirely less frequently, about maybe 1 time every 3 weeks. The gateway never seems to have any problems.

The WAPs are linked to the gateway with 4 TP-LINK TL-PA2010KIT powerline adapters. Upon setup, I made sure to use the buttons on each to connect to the powerline adapter connected to the gateway while both were plugged in inside the same room, then moved to their proper locations.

My question is if there is anything more I can do with the current hardware. Networking is kind of a weak spot for me, so I am not sure if there is something else I need to do with the powerline adapters themselves, or if there are settings I am missing in the routers' configurations. My hunch is that the router itself is insufficient for serving the amount of devices in the area. The WAP in question serves around 7 people who have at least 2-3 devices each.

Any help is appreciated. Thank you in advance. = )

We have had many problems with the Linksys E wireless routers over the last year or two, especially the E1200. We ended up switching to ASUS wireless routers because of the exact same issue you are seeing here. Random crashes requiring reboot, often multiple times a day. I'm betting that is your problem then.

While it is improved over previous versions, powerline adapters still are not ideal for running networks through, especially anything requiring a decent amount of throughput or continual connections. It will do in a pinch, but it may cause you some issues, and not just with your network equipment but also with any electronics connected through it.
