How do you get two BT home hubs working on the same connection?

Asked by tudorbob (6points) December 17th, 2008

I have two BT hubs and want to provide wired broadband to two computers in different areas of the house. I already have phone cable in each area but when connecting the two hubs they cause a conflict and the broadband disconnects. I have tried to switch off DHCP on one hub and allowed the other to configure that, but still it is buggy. Any suggestions would be appreciated.

I know this is not needed to answer your question, but why do you want the two computers to be a wired connection?

Wired connections are much faster and consistent than a wireless connection.

Wireless connections have also improved a lot over the last fews years and run a lot smoother. I’m not trying to argue, but wireless speeds and wired speeds are coming closer and closer together. On my laptop I actually achieve the same speed as I do on the desktop that the modem is plugged into.

On my desktop I can get speeds of up to 7.4mps and on my wireless I have only ever had speeds of around 2–4. I really notice the difference in downloading large software packages and streaming media such as iplayer. In addition my wireless crashes when using my mac for streaming media – I am unsure as to the reason but it is not isolated to me.

Oh wow…that is bad for wireless. I have almost a 14mps download speed and almost a 4mps upload speed on my laptop. All my music, videos, and photos are streamed via my network and all the files play as if they were stored on my computer’s HDD.

Why do you have two BT Home Hubs anyway? Shouldn’t you just need one?

tudorbob's avatar

Okay – let me rephrase the question. If someone, for whatever reason they may have, would like to use two BT hubs in a single network to provide two wired ethernet connections on the same phone line at different ends of a house – how would you do it?

I have two BT hubs because they keep sending them to me everytime I sneeze in their direction.

I would just connect both wired connections to one of the hubs and ignore the other one.

I’m not sure I understand your setup—are both hubs currently operating on their own, or is only one currently operating?

tudorbob's avatar

One is currently operating. but instead of paying for 30m of network cable i was wondering if anyone had an idea how to use two hubs as i already have phone lines in each of the room (same number).

BT probably won’t allow two of its routers to separately gain access to the network. You could hook them up to eachother directly through a crossover cable, but then you’d have to make sure you could disable the routing capabilities of the secondary one (which I’m not sure whether the software on a BTHomeHub will let you do), and which means you’re paying for 30m of network cable anyway.

Sorry, but I think you’re out of luck here. :( 30m of network cable isn’t too pricey!

@hypeserver: the theoretical maximums of wireless connections are approaching those of wired connections, but they’re still off: 580Mbps in ideal conditions for a draft wireless standard vs. 1000Mbps for a wired connection. Ethernet in the data center is quite commonly 10Gbps now. In any professional situation where reliability or throughput is required, a wireless connection would be unacceptable.

That said, most home downlinks (in the US, at least) haven’t even hit 10Mbps yet. For web browsing, there’s often little or no difference: you’re not getting near the limits. For file transfers, though, wired is the way to go.

On to the original question. @tudorbob, assuming “BT router” is synonymous with “DSL modem”, you won’t be able to get two connections on the same residential line. Every modem needs another modem on the opposite end, and there’s only one port in your ISP’s DSLAM for your house.

If you’re balking at store prices for 30m of CAT5, the web is much cheaper.

@aaronbeekay Yeah, the “BT Home Hub” is an all-in-one modem and router.

ive got two bt hubs 2 and i wanted to no can you just run a Ethernet cable from the hub in my lounge to other hub in another room will it connect to the internet? and also do i need to connect the other hub not the lounge hub to a telephone line as the hub in my lounge goed through the adsl

Hiya mate why do people argue. No question is a silly question if you don’t know. Just answer the question. Use an ethernet mate connect ethernet hub one to ethernet on hub 2. You get two routers. With 3 wired connections and 1 wifi connection on each hub extending your broadband and wifi coverage. You only need connect 1 hub to your phoneline as all you have done is inceased your local internal network. I currenty have 3 hubs linked together with 3 wired pcs 3 wired xbox 360s 1 wired nintendo wee and wired bt vision box. Also three connection points for wifi and the two socket boosters you get from bt now unused and in the box. Hope this helps you.
Best regards Psycojohno
