Hi, I was using a 2640T but wanted to upgrade my wireless and wired LAN. Now I use the 825 for wireless and also wired since it has gigabit ports. I connect the 825 to the 2640T, disable wireless AP for the 2640T and even took out the antenna. Now the 2640T is effectively just an ADSL modem. My question is, they are put side by side, even though I have disabled 2640T wireless, would it still affect my 825 wireless performance. Thanks in advance.
