Hello again Zhilong
1. No I havent tried connecting the PCE-AC66 to another router. I will try that on wednesday and get back to you.
2. You say that the PCE-AC66 might be the problem hardware issue. Is it something you have heard of before ?. Because the product is very new.
If I cannot conenct my PCE-AC66 on a diffrent router I guess my last option is to RMA
