Query: Netger Wgr614 v6 troublesome

I used this product for 18 months and had in for technical support 4-5 times because the product keeps flaking out. The last time I called, I had to pay $36 because the 90 day warranty had run out, and the problem was never resolved. Basically, I have to pitch the thing and buy a new router.
