Query: Really unstable and full o features that won't work

I had this router working mediocre for like a year, it sometimes stops working but you just need to restart it, I had to do this twice a week.It suddenly stopped working for some devices including my mother's Nokia N8 which will refuse a connection but it worked for my iPhone so I went and I decided to bypass all its features and use it as an access point, it worked fine for a while.Finally it got worst two weeks ago, I tried everything but nothing works, next time I will go with an more expensive router and save myself some pain.
