I want to have 2 internet connections broadcast over 2 routers in my home. What's the best approach?

[cdhall811]

Connection #1:
DSL (10 Mbps) used mainly for work
I don't want to drop my DSL connection totally because it's slow, but more reliable than the cable.

Connection #2:
Cable
30 Mbps (Used for gaming / Netflix / other wireless devices)

I think your are going to have to get two separate wireless / wired routers and perhaps set them up to use different bands (ie one on G and one on N)

If you want 2 connections and 2 routers, then just get 2 contracts.
One from a DSL provider and the other from a cable provider. You can either use the wireless router that they provide, or buy 2 separate routers.

You will need separate modems and routers for each internet connection. You will also have to have different SSID names for your wifi netorks.

If using two 2.4Ghz routers, make sure they are on totally different channels, like 1 and 11.
Other option is to get a dual band router, and force one service to use 5.8Ghz, and buy 5.8Ghz adapters for the PCs that you want to use that band with. All 5.8Ghz adapters are dual band, so you can pick which router/service you want to connect to by selecting the band internally in the PC.

You won't have a WIFI problem just broadcast different SSIDS and have them on different channels but not adjacent.

If you have a network printer, then you have to pick which network to put it on. Some printers have a wired and wireless interface, but can only use one at a time.

I suggest you purchase a dual WAN router. The CATV internet goes into one WAN port, the DSL goes into the other. Cisco Systems (not Cisco Linksys which is home grade) offers several. Probably the Cisco Systems Small Business Router family would offer something that would do the job. In fact you can configure the unit to detect failure and fail over to the alternate feed and do load balancing with this.

A dual WAN router has a common LAN - which means that, regardless of the WAN (Internet) feed, the LAN side behaves the same; you have one subnet, can be wired, wireless or a mix of wired and wireless.

In your case this is what you want.

I LOVE People's answers...

You will need this and that, put this that here. Noone actually read the question, people in yahoo just reads the first 5 words of the question and answers all kinds of crazy stuff.

That would be 1 Approach.

Another approach is, call your DSL ISP and ask them, can they increase bandwidth? DSL Can match 30mbps, however, this is raw and your own line.

The difference you see with Cable and its 30Mbps is, its not quite 30Mbps. Cable is either coax or Fiber-optic. VERY FAST SPEEDS, but this Fiber-optic is shared among your neighborhood. When they tell you 30mbps, you can count on 10-20mbps, depending on who's hogging the bandwidth most on your neighborhood. However, if you do tell them you want more bandwidth, they can give you more.

DSL is a dedicated line just for you that runs on copper, when they say 10mbps, they can literally guarantee you that. With the exception of 10Mbps download and maybe 2Mbps upload. Now if you increase yours to 30Mbps, this is literally all for you, and not shared by your neighborhood.
