I've been on this forum for quite a while now and i've seen that ppl located in US use routers for home use wish is very uncommon where i come from.
So i was wondering why do u need to use routers at home?

I am very familiar with routers , i am a CISCO CCNA certificate and i know how to configure routers and all about IOS configuration and using routers to connect WAN's and all, but its just unfamiliar for me to see routers used at home.

I've come up to a conclusion that maybe u use routers to share the internet connection over many computers at home and since the network that provide u the internet is defenitly different than the network u will use to connect ur home PCs than u need a router to make the connection between the 2 different networks, but still i've seen that very non-techie ppl buy those routers and i was wondering how do they know how to configure them?? or maybe they r routers with no need for configuration?

i appreciate any help on this one.
thanks.

Hi Wassim,

Here in the US most people use a router for two reasons.

1. It makes it easy to share a high-speed internet connection among several computers located in different parts of the house. here is a link to the manual for my own router; you can judge for yourself how difficult the setup is, but I think most people can do it themselves, or find a geeky friend/family member to help them. The hardest part is securing the wireless connection (if they use wireless; most people do).

2. The router is also a hardware firewall using NAT, so that even if the computers on the network do not have software firewalls installed and configured, at least there is some basic protection in place. I always recommend that people install a two-way software firewall on each computer, but I have a feeling many people do not. Configuring the software firewall is more of a hassle than setting up a router.

Hope this answers your question.

Cheers,

Dave

Hey Dave,

now i do have a clear idea why ppl use routers in the US for home use, especially if u wanna share a DSL connection, i guess those routers r more commercial and for home use than the professional ones that i've seen, anyway US ppl always do things in a different way ;)

thanks for ur help.

cheers.

And here's a ton of comments and pictures of Linksys WRT54G series, it might be more familiar to you due to Cisco

The only difficult part in configuring the router is matching the configuration of protocols to what your ISP wants (such as PPPoE and others).

There is one other reason for a router. It relieves your computer of dealing with people pinging you all the time, in which case your software firewall has to do a lot of work on your computer, and log thousands of break-in/connection/noisy traffic attempts. Make the router work instead and your computer's firewall (I assume you have something decent besides the built-in), that's what the hardware is for.

Well since we dont have real IPs here, ppl cant ping us or connect directly... but its a good reason also to use routers and it pretty cheap there in the US, i cant get less than 90 to 100 $ here

thanks tos226 & tg1911.

While routers are the most common connection method in the US these days - in the past people also used hubs and switches (my wife has a hub in her office). But, that's from the days before the internet became so popular.

The primary use for routers these days is:
1) Connect multiple computers to the internet (not many people use it to share stuff between the computers on the workgroup)
2) Simplicity. Routers and wireless routers are so easy to setup that almost anyone can connect computers to the internet. My daughter knows nothing about computers, yet she went out and bought a wireless router and hooked it up herself without any assistance.
