Thanks for your reply. Is a switch the same as a wired
router?
Switches and routers are functionally different. A router will allow you to use 2 or more PCs at the same time, a switch will not.
Can you please send me a link of some good wired router as only the new PC has a wireless internet card whereas the old PC can only use wired internet?
The model I recommended is available on
Flipkart Netgear WGR614 Wireless-N 150 Router (White) | Router | Flipkart.com
These switches need power supply, right?
Yes, BUT you can get ones that draw the power supply from the Ethernet cable but in this kind of situation where you have such long cables it would not be a good idea and would likely defeat the purpose. Also, they're not cheap.
Are there switches which come with a backup power supply?
Commercial ones do, but they're not cheap.
My computer is in my room which has a battery but if I'm using a switch, I'll have to fix it in my drawing room where there is not battery, so any solution to that?
Get a
UPS. Again, not cheap. If you're worried that the Internet will be down during powercuts, it probably will be anyway because Beam's own equipment will be drawing power from somewhere and in many cases is not backed up by battery. Unless there is another electricity source, it too will go off in the even of a powercut.
Also, by using a switch will my internet speed reduce? If so, by how much?
It will at least maintain the speed you are supposed to get, but most importantly it will allow you (technically) a cable length between Beam's equipment and your computer of up to about 180m by repeating the signal.
Also, I'm going to use this internet on 2 PCs at the same time (like bobbyguitarist mentioned above). I'll be using internet on the the new PC very frequently and the old PC infrequently but both will be on simultaneously. Will just leaving the internet connected / uploading something on the old PC affect the download speed on the new PC? TIA.
To use 2 PCs simultaneously you will need a router, no question.
