Repeater bridge with Comcast modem and Linksys Wrt400n
Posted on 2014-01-10
OK, so I recently updated to blast service from Comcast. To shorten things up I needed to swap my old 2.0 modem for a newer 3.0 modem. The model I got is an Arris TG862G/CT. Which has the built in Wi-Fi and switch. I thought great but wasn't sure about the wireless capabilities. Sure enough the signal was very weak compared to my Linksys WRT400N. So my first idea was to check if DD-WRT was available for my router? It was. So I installed firmware: dd-wrt v24-sp2 (12/24/13) std. And planned to use it to spread my wireless signal as a repeater bridge. The problem I'm facing is that the IP on the Comcast modem is in this format: 10.0.0.1 and the Linksys uses 192.168.1.1 So while trying to follow the DD-WRT tutorial to set up the Linksys for repeater bridge I tried changing its IP to reflect the Comcast router. But after doing so I could no longer access the settings menu on the Linksys no matter what static IP I'd give the computer. So I'm wondering if it's not possible to use my Linksys with the Arris together for the purpose I wanted due to the difference in IP format? If not my only option would be to call Comcast and get them to set the Arris up into bridged mode and just use my Linksys as the router like before especially since it now had DD-WRT installed and can pump the wireless signal up a bit more. But I'm not sure if in doing so I'd be hindering my data speeds since my whole purpose was to get faster internet speeds. I'm currently averaging 57mbps down only using the Comcast modem. So I'm not sure if the Linksys can effectively support those same speeds? Also the Linksys Wrt400n doesn't support ipv6 from factory but read that with DD-WRT it can be made to do so. Not sure that it is even relevant in any way? And I've already asked this same question in the DD-WRT forum but haven't received a single answer yet. So I came here hoping someone can enlighten me. Whether it be with useful info or to flat out let me know that what I'm trying to do won't work. Also the tutorial on DD-WRT for setting up the Linksys to repeater bridge mode isn't very clear. And I searched on the things that weren't clear and there were various different answers which kind of confused me a little more. Main one is that in the tutorial it says to pick the option in the settings to repeater bridge from the dropdown menu of the router but that exact option doesn't exist in the settings menu. In my search results some would say to choose bridge. Others said client bridge (routed). So I'm not sure if that's the reason why I can't get it to work either? Sorry for the long post just trying to explain myself the best I can. Thanks.
