When I need to know this answer I get wired. There are some folk that expect solid answers to wireless questions like this but this one is where "it depends" on so many factors that the only way to sniff out if it's the wireless is to try it without it.
I am using a dd-wrt router driver on my Netgear WGR614 v.8 router and it is set up as a repeater bridge. There is a separate router downstairs that is being used under different security settings. My access point and repeater bridge use WPA2-personal and AES security configuration and the downstairs router uses WPA-personal and TKIS security configuration. Are the different security settings going to cause my internet connection to hang or be slow? Right now, I am getting internet just fine most of the time, wired to the repeater bridge, but some times it slows or stops completely. Could this be due to the fact that I use Comcast internet, since they don't give users a dedicated line? Or is it possible that the different security configurations are conflicting with each other? One other thing- dd-wrt's website states in their instructions tells me to use the same channel for the repeater bridge and access point. Will it still work if I change the channel on one of the routers in the repeater bridge set up? What if I changed the channel for both the access point and the repeater bridge routers, as long as I use the same channel? I asked these questions at the dd-wrt forum but got no response.
