Hi all,

Been searching the web for hours and cant find a clear solution so,

i have wifi comming in to the building but no acces to the router, i bridged my wifi with Ethernet on the pc and plugged the cable in the wan of the second router (dlink dir615). The goal here is to create a separate network using the dlink as my 'main' router to connect, well everything :) so i flashed ddwrt firmware, set static ip to 192.168.1.x (instead of original routers 198.168.0.x used the same subnetmask as the original, tried gateway at 192.168.0.1 (first router) and tried the ip of my pc's wifi adapter, what technically works as a gateway?? Tried different dns adresses like google dns, standard isp adress and even gateway adresses...dlink is set as a dhcp server with range from 192.168.1.100 as primary is set to 192.168.0.x. put operating mode in router and set dynamic routing to lan+wlan. The router works and hands out ip's but there is no internet coming through and I'm out of ideas. If more information is needed just say so and I'll post it ;) i know a thing or 2 about computers but I'm a total noob when it comes to networking :D

If you are going to use your PC to covert the signal you might as well use ICS and let the computer be the router and use the dlink as a AP to provide wifi. You can not just simply bridge WiFi to ethernet..at least when the wifi is encrypted. Part of the encryption includes the mac address of the wifi equipment and it will not pass the mac addresses of the second router

In general it is not a good idea to use your PC as a network device. You have to be careful about CPU load issues on your PC to not disrupt the traffic passing though it. This is a very messy thing to get to work since a pc is not designed to be a network device.

If you had a dual band router you can use dd-wrt to do this, it will receive signal on one radio...

If you had a dual band router you can use dd-wrt to do this, it will receive signal on one radio and can use that as a WAN. It will then use the other radio and the ethernet to act as lan. You might be better served to either use another old router running dd-wrt as a client-bridge instead of using your PC to receive the signal.

Mm that's what i was afraid of.. using the pc as a router is out of the question due to cpu limitations, it runs buggy as is, just looked some up so if i read this right a dual band will take wifi from one and convert it to lan? Like i need it to.. but will it be the same network? One of the problems is that my chromecast is connected to the network and everyone can see what I'm viewing, pause or even stream something else to it :( i also have a lot of shared media and altrough they cant get to it without a login its better to be safe than sorry so a secondary network is realy necessary. I am however looking in to some cheapish dualband routers atm. Thxr the reply

It depends how you run it. If you use a wan port on a router...or define a wireless radio as wan the networks are separate. The only other way to run it is to run as a repeater. This requires a special feature called WDS (this is to fix the encryption mac issue). In this case the macs are exposed but WDS is not enabled on all routers and if you do not control it you can not turn it on.

Hehe i have seen the WDS option somewhere in here, but if, like you say the macs are exposed, is there a security risk to it?
Sorry for all the questions, like i said total noob on networking ;) but i get the feeling i can understand why some people say i talk chinees from time to time, thats what U are doing now :D gonne start googling some more to get a better understanding of what u just wrote
