I purchase the 5350 router because I be a new Comcast customer and I do not want to pay a monthly fee to lease a router\/modem . I find this device on the Comcast approve list . after my cable be install , I be have problem with the router . my MacBook would connect to the router but the connection be not very reliable - my connection would frequently drop which be incredibly annoying . my work laptop run Windows 7 be not work with the router at all -lrb- it would connect , but I would not be able to receive any datum -rrb- . I be ready to return the Zoom 5350 but I google my problem and I find some solution . specifically , I read that Comcast customer support be tell user of this device to turn off the IP flooding detection feature in the firewall setting . this seem to have work - my Windows laptop be now able to connect and my MacBook connection be more reliable . to make this change go to http:\/\/192.168.0.1\/ , select firewall from the top menu , uncheck IP flood detection and click apply . this seem to fix the problem , but I just make the change this afternoon . I will update my post later , if the router become more or less reliable . I be give the router 4 star right now , but I would say this be closer to 3.5 star because the aforementioned fix be not very obvious -lrb- although Comcast should have make this setting know -rrb- . ------------------------------------------------------------------------------------------------------------------- just a follow-up . I have not have any major problem with the router since I make the change describe above . I still would keep my rating at 4 star since configure the router be not particularly intuitive .
