The "very unreliable" comes from the fact that wireless is prone to be more "problematic" than wired clients. is my opinion an I am sticking to it. period
Yeah, just turn on a microwave oven when you are using a "marginal" link, and the link will be gone for a couple minutes. I'm in a situation where I have to use a wireless link and to get it to the point where it has become reliable it took:
1. A 1000 mW amplifier (up from the base power of 50 mW of my router)
2. A 15 dBi Yagi, pointed at the other end of the house.
Net effect at the far end: Starting signal: -69 dBm
After amp and antenna change: -42 dBm
Net improvement: 27 dB!
Now I can play back WHDVR titles in both directions across the entire length of the house (80'). HR44-700 (router/amp/antenna) > HR24-200 (Wireless CCKI) > Separate Swim Dish
The CCK integrates my 2nd dish with the main system over the link described above.
Wired is always better than wireless, if it can be done. Any time I have an option of ethernet or wireless (and I have quite a few devices that will do either), I've always gone wired and never looked back. When there is no option, that's when it pays to upgrade both the transmit and receive portions of the wireless link.
