I pulled my hair out with D-Link routers and extenders for over a year. Common problems, dropped signals, power cycling etc.
Since I have bought what seems to be the perfect router, I thought I would share the info with all. (No, I have absolutely no connection with this company).
The router is made by Parkervision. Just google for their website and read about it. I thought, what the hell, I can spend another $100 for my sanity. I live in a 3600 sq foot, Masonry--tons of angles, house. This one router gets through the whole house without any problems, I also can go out by the pool and work, all my porches too! Worked out of the box and I have not had any dropped signals, nor had to power cycle only once every two months or so, if that.
Just thought I would share my good fortune in finding this.
Anyone want a DLink router and 2 extenders? I'll sell cheap!
