Router and isp's

Does a certain make or type of router have anything to do with an ISP. I have seen posts on the forum where people have asked if a certain router is suitable for a specific broadband connection e.g is Dlink router suitable for my tata broadband connection?

From what I know routers are in the way same, but have different signal strengths and are of different makes. Is there anything more to the type of router and the isp connection?

There are some things you need to consider to make sure that the router is compatible with the connection, otherwise there is nothing major which should stop you from choosing a router for an ISP.
Some other differences between routers are the number of antennas a router has, the more the antennas a router has the more chances there are of a better signal. Also a router has bands and the two choices you need to choose from are single band and dual band.

Some routers will not have the appropriate way to connect with the ISP. This is often the case for North American routers that are used in Europe or Australia, so that can also be the case in India. But I have personally not run into this and have run my US routers in India.

All routers are by default manufactured to work with any ISPs.. The technology should match..(ADSL, LAN, or TV). It will work. There are some cases where the ISP 'locks' a router to its defualt values, and the user has no choice, but to discard the router if he wishes to terminate the connection. This is the case with most of Tikonas router.

What has that got to do with an ISP??
What you're mentioing is about the router features, not the interchagability with ISPs!

This is wrong. There are some routers manufactured for different markets that DO NOT have the appropriate connection methodology. I have seen this first hand on several support sites where someone is taking a router from one region of the world and using it in another.

ISPs can lock devices (similar to cable modems) where there options cannot be changed. But this is usually remedied by completely factory defaulting the unit if you have the ISP connection information in another source somewhere.
