N66U on Repeater Mode Very High Latency

[lillypad_33]

Hi Everybody,
I have a weird network setup. The house I am in has many dead spots and I can't seem to get a decent configuration going.

The router provided by the cable company is in the basement in an electrical box and reaches nowwhere in the house.
I've got an ethernet cable extended all the way upstairs 2 floors to a N56U which is set up as an access point.
The N56U has decent range, but cannot penetrate all the way back downstairs where I need it!

So... I've got a N66u on Wireless Repeater mode. The connection to the N56U is very good.... It varies between 350 and 450 mbps. The issue I have is that when connected to the "repeater" SSID, there is very high latency. The speed seems good, but the latency is killing me. It literally takes 15 seconds before being able to reload simple internet pages.
Does anybody know of any settings that might be causing this latency?
Currently the DNS and DHCP are being provided by the router from the cable company all the way in the basement.
I keep racking my brains, and simply cannot think of a better way to set up our household.

1. Take the ISP provided router out of the electrical box or, disable it's radio's.
2. Don't use a repeater.
3. Use the RT-N66U as your main router. Much, much better signal than the RT-N56U is capable of.
4. Use john9527's firmware fork for your 'N66U.
5. If you still need to extend your WiFi network, use the RT-N56U as an AP (wired).

Make sure you have the latest firmware on both routers. Make sure you have performed a full reset to factory defaults on both and then minimally and manually configured them to secure them and connect to the ISP.

You may want to try Padavan's firmware for the RT-N56U.

WiFi is a time shared medium. As you have found out, using a repeater on your network makes for a poor network experience as the repeater is using more than twice as much time as any client can for each WAN or LAN request. In addition, the repeater is also interfering with the other nearby networks too (you are sharing those time slices with those routers too).

You can try to manually set an overall better channel (and channel width) if you insist on using a repeater in your network. But I would suggest you follow the steps above, in addition to setting a manual channel to get the best network experience possible.

The following links will help you get your routers and devices to a known/good state so that you can troubleshoot more effectively to tackle the issues your network faces.

The following link shows what is possible with a current router (and others have reported that the much cheaper options from Best Buy, the RT-AC1900P, may have just as much an impact too).

Maybe try wired solution, so Basement router <--cable--> RT 66U <--cable--> RT 56U

or

Basement router <--cable--> RT 66U
|--------------------<--cable--> RT 56U
