I purchased a DIR-600L back in October here while living in Taiwan on work assignment, and have had no problems until a week ago, signal was strong, no issues. Now, I have family from back home visiting, and the wifi has turned to total junk: My PS3, sitting 10 feet from the router, shows 27% signal. I sit right next to it with my phone, and have around 60%.
I did a factory reset, no luck, so I checked out the firmware, and have upgrade to 1.14 (I have hardware version A). I again did a factory reset, and still no luck. I've tried manually setting the channels, I've tried changing the 20/40 MHZ setting, I've tried changing from wireless mode B/G/N to just B/G, and nothing. The wired connection works fine, previously I was able to use the wireless from about 40 feet away down on the other end of my apartment, now I can barely use it 10 feet away in my bedroom.
I don't speak any Chinese, so returning to the store now would likely be a no-go, also it was 5 months ago and I'm not sure I even have the receipt anyways. Any help would be greatly appreciated.
Thanks,
