I have been having issue of wireless signal since last couple month. Of course I even tried the newest firmware, the one that came out today. it was not really helpful, so I went back to default fw, and did the speed test of each fw. What i found out was after 260 version, it got worse and worse. also I tried dw version of 260, it shows me that faster speed, but stability was the issue. Am I the only one having issue?
