Sudden Drastic Drop in Wifi Signal Strength - Dlink DSL-2730U

Hello forum!

I'm having problems with the wifi signal strength of my Dlink DSL-2730U. I bought it 2 months ago and it was working ever so perfectly. I could get strong signals in every corner of my home, but from the past few days, the signal strength has dropped drastically. Now I have to sit very close to the router in order to connect my laptop. For my iPhone, I have to stand right next to the router to be able to connect. I never changed any setting and I don't understand why is this happening.

I've been reading online articles and forum topics and tried troubleshooting, but nothing has worked yet. I have tried changing the wireless channel, bandwidth, multicast rate... but the problem still continues.

Here are the screenshots of the wireless settings page -







Please help, forum.
Thanks!

Try Channel 11.
Also report SNR Attn data. Change mod mode. to GDMT.

Thanks for replying, essbebe!

1) I tried channel 11, but no perceivable gain in signal strength.

2) Is this what you mean by SNR Attn data-



3) GDMT is already enabled

Yes. Disable Adsl2+ button. save REBOOT.
Attainable rate will reduce for stable connection.
Channel 11 default.Position Router at a higher plane ( height)
Confirm whether Antenna is detachable to add a higher gain antenna. ( 5 dBi)

@essbebe
Thats utter bullshit. Whats SNR got to do with wifi signal?

Your router has gone kaput! If you are not on a shoe string budget then get a new one else check if you have moved things around like keeping your router on a metal surface for example? Some thing with copper nets or something been placed around the router?
