How exactly do Pocket WiFi devices work?

Installing a wifi network?

• I have had a single-router WiFi network for 5 years now and have used countless different routers, trying to find one that will give me coverage for the whole house. I have not had brilliant success. My current router is a virgin media router that was installed by virgin. It has four ports and gives out WiFi but gives me dead spots such as the lounge and the downstairs bathroom (who doesn't check Emails on the loo). I have recently bought a 40m CAT6 Ethernet cable to connect my TV, Sky box and blu ray player, that are in my lounge to the internet. It runs fine to my lounge but I can only connect one of my devices to the internet at any one time. I had read something about Ethernet switches that give you more Ethernet ports, which I could plug my 40m CAT6 cable into as an input and then have individual cables running out to my devices as outputs. I realise that this could be done cheaply (i.e. £10 for the internet switch and maybe £20 for cables) but then I remembered my problem with WiFi, especially in this part of the house. I was wondering if it would be a good idea to get a second router which not only gives me more ports in this part of the house, but gives me WiFi. So, my questions are: Can two routers work synonymously in one house off of one phone line? Would I be able to connect devices such as phones and my iPad to both WiFi's at the same time so I can move around the house without changing network settings? Would a Virgin Media router work fine with another branded router such as Netgear? Or should I nip this idea in the bud and just get a Ethernet switch and not bother with the hassle of having two routers? And any other advice would be greatly appreciated! Thank you :)

• Answer:

  Pretty much all those options will work. Best is probably an extra wifi router with some Ethernet ports. You'll need the new router on a separate sub-net. Which may mean you can't network print if you computer is on one router and the printer is on the other.
