Tenda W1800R Signal Issues

Hello,

I have been a user of the Tenda W1800r for about 2-3 years roughly and I have always suffered really bad signal issues on it. I cannot compare it to the stock firmware as it was flashed with tomato within 10 minutes of me taking out of the box.

I have used tomato by shibby up until today and my only annoyance has been this weak signal up until today when I tried RAF tomato but the issue is still very much there.

To give you an example of how poor the signal is when using a Wi-Fi analyser I receive about -40db when I'm practically sat on top of the router which isn't too bad however if I then move out of the room with the router in signal loss happens fast by just moving out of the doorway signal has dropped to around -62 and if I go to the opposite side of the wall that the router is next too its -64 this is very shocking as it means that most areas of the house just have devices disconnecting due to this issue as for example the area we cook (the word kitch**n is not allowed lol) directly opposite the room with the router in gets about -80 so even thinking about using it in the garden is laugh.

I currently live in a bungalow in a rural location so I can ensue that interference is practically non existent.

I really like this router however I would just like to be able to use it like a normal person would and expect the signal to cover the house especially in a property of this size.

I have tried many different set ups and countries from EU to Singapore to US and UK non of which make a difference and the EU actually losing the 80MHz channels.

Any help would be much appreciated thanks.
