We just signed up for xfinity last Friday and have the Arris modem. For the first couple of days I was able to get the 25 mb/s that I am paying for on my laptop wirelessly. Yesterday my dad wanted to hook up his ancient laptops to the wifi. These computers are old and don't support the security that was currently setup for the wireless connection, so I had to "dumb down" the security so that his computers could connect. This seems to have coresponded with a decrease in the speeds I can now get on all the wireless devices connected to the wifi. Now I'm not sure if these two events, changing the security and the decrease in wireless speed, are related, but I may try changing the wireless security back up to where it was and see if that has an effect on my speeds. Like others have mentioned, when I connect to the modem directly I get the 25 mb/s that I am paying for. I am willing to buy a wireless modem and set the Arris in bridge mode. Is this something that is complicated to do?
