HI GUYS!

I think this is the right place to post my question...
Currently I am using a Netgear N300 Wireless ADSL2+ Modem Router up to 300Mbs.
I am on a 4mb line with Telkom.

Here's my question; How do connect two routers to one home network / one adsl line / connect two routers in the same house?

I have a second router which im not using but want to connect to extend the Wifi coverage in my house. The second unused router is a Billion W40 Wifi / ADSL router.

Is this possible and if so how would one do this?

Any help would be appreciated!

Thanks again :)

if you are gonna use a cable between the two routers then you just need to specify the same ssid, encryption and password on the second router as well as set it to use dhcp relay and point it to the first router's ip so that the primary router can handle the dhcp properly.

as to whether its possible by only using wifi (no cable between the two), I dont know.
 
If the second router is capable of being an AP bridge or repeater then it's possible wirelessly. I'd just run a cable for reliability/performance.

It is possible. My Airport Express extends my existing wireless network. It's a one click thing.
Not sure exactly Netgear and Billion do it though. Open the configuration utility for the Billion and it should ask you how you want to connect it to a network (Extend or Join)

Its possible via wireless if both have WDS
 
Hi there,
Yes it is possible. Using a cable is my preferred solution and as has been indicated you need to have the same SSID in both routers, and set up to use the primary router for DHCP and make sure your channels are at least 4 apart e.g. use channel 1 on the primary and channel 5 on the secondary.
You can find more details on this at my blog repository of useful ways to do these sort of things

Regarding the channels, if they are the same will it simply not work or will it be slower or?
 
Turn off DHCP on the second router
Make sure the address is in the same range, but does not clash with the first router

Actually, you must set it up as a DHCP Relay Agent, so it still obtains a DHCP IP address from the primary router.

Most modern routers have a facility call WDS (Wireless Distribution System) that makes this process easy and seamless.
 
Doesn't a relay route dhcp requests between ip subnets? The dhcp request is a broadcast, so it will go to all ports in the broadcast domain regardless of whether there is a relay or not.

Broadcast messages are only sent over the same network segment. UNLESS a specific route is defined in the router. This is a router, not a switch it was referring to. Even with the same IP range, the router only broadcasts within its own segment.

As I said, the use of the WDS feature if it is supported is preferable, to avoid having to create routes or define other settings.

That being said, it might work on some routers - but it is not the design or function of a router to do this. A switch or wireless repeater or even a WAP is designed for this. Horses for courses.
 
The router is the bit routing between the LAN and the wan. Got nothing to do with LAN to wireless. LAN to wireless is the same broadcast domain and in effect works like a layer 2 switch. Which sends broadcasts to all ports in the broadcast domain.
 
Already tried WDS on the Do broadband Netgear N300. Doesn't play well with others and for some reason it wants to disable all WiFi encryption to use WDS. Could be a firmware issue but I never bothered investigating further. A Billion to Billion on the other hand works flawlessly. And yes, set the one router to a relay or your NIC is going to keep jumping between DHCP servers. Sinbad is correct. WDS creates a bridge. If you can go CAT and latency is important I would recommend it over WDS though. My config has my router IP's and DHCP ranges on the same subnet - no additional routing required. WiFi channels need to match on both routers and so does the encryption type and key. SSID can differ but keep them the same if you want seemless roaming. If the routers are far apart use 20Mhz channels otherwise you end up with frequent drops and terrible performance.

How are you by the way Sinbad. Lonnnnggg time no see :-)
