Wondering if anyone's seen this issue before:

Connected to Cable Modem: RT-N16 [1.28.7500 RT K26 USB Std]
Wireless Ethernet Bridge: RT-N12B1 [1.28.0500.5 RT-N K26 Tiny]
NVRAM was reset on upgrade and settings manually configured afterwards.
Wireless is running in AUTO, WPA2+AES security — 40MHz width, Channel 1 (least crowded according to InSSIDer).

Wireless stats on the bridge are roughly hovering around:
RSSI -47 dBm
Noise -82 dBm (yes, the noise is fairly high)
Signal Quality 35

Every once in a while, the wireless rate (normally hovering around 270mbps to 300mbps) on my RT-N16 will drop down to 11mbps and just get stuck there. Going to Basic->Save or doing a disable/enable of wireless will pop the rate right back up to normal. I've tried with smaller width (20MHz), different channel (11), WDS instead of Bridge mode, and turning Interference Mitigation on/off, but this happens pretty regularly (about once a night) and seemingly at random (I don't notice it until my game pings start skyrocketing and downloads slow to a crawl). Anybody know why this type of behavior would occur?

Try to update RT-N16 to 0500.5 build then you have same version of wifi drivers.
When you can read 11mbps what speed do you measure then?
That is normal speed shows that after no traffic for a while, but usally come back.

I have seen a few people preferring the RT-N builds on the N16. No ill effects from running it, I assume?

Wireless is actually maxed out at 11mbps — i.e. running speedtests while hardwired to N16 are normal, any wireless connectivity [including over the bridge] slows down to a crawl. Restarting wireless on the N16 fixes it.

Are you sure problem is with your router ? Maby you should look at your client side. Upgrade drivers.
Some intel card is really crappy s***t ! Good palce to download driver is: ht tp://www.station-drivers. com/

Problem persists even if I shut off all other clients (phones, laptops) and only have the bridge connected.
