My problem is that all my wireless devices, such as ipad, smartphone, iphone are still connected to the router, but all of them loses connection to the Internet out of the blue.

Chrome will time out
Speedtest.net application will say "network issue"

However, my PC, that is connected through cable to the router is still working properly.

Rebooting the router through the 192.168.1.1 does not fix the issue.

I have to physically turn off/on the router and only sometimes, it fixes the issue.

But today, turning off/on the router partially fixes the issue, but the connection is very slow, (only about 0.2 mbps) in the wireless devices, While PC can get 7.5 mbps. Turning off the cable modem fixed the issue. Please note that this issue only exist in the wireless, not in the PC.

Currently, I'm using Auto channel (I've checked using wifi analyzer, my area is very quite, any channel should work properly)
Mode : 11bg
Channel Width 20 mhz
Max TX Rate : 54

Transmit Power : High
Beacon Interval : 100
RTS Threshold : 2346
Fragmentation Threshold : 2346
DTIM Interval : 1

This router has been working for the past 3 years and now, it started to have this problem. Does anyone have the same issue?
