hi, i wonder if i can use 2 wireless router at the same time? coz the other router is at the other room that my laptop cannot find the signal. so can i connect another wireless router to the first router and place it in my room? using just one modem. hope you get what i want to say. or can you give me an advice on what to do. thanks so much.

There are wireless repeaters, as well as wireless routers that have a configuration option to act as a repeater. Those options may work for you. Another option would be to replace the antennas (compatible ones) that have better coverage. Another option would be to move the modem (and router) to a more central location in the building, so it would cover both areas. A second router usually needs a cabled Internet side connection. Best wishes, Keith.

I am going off to college very soon and I have a question about networking. In my dorm there is ONE Ethernet jack in the wall. I have many devices that use Ethernet as a means of connecting to the internet. My question is would I need a wired switch or a wired router to share the internet between these devices.

P.S. I say wired because my college does not allow any wireless broadcasting what so ever.

The ethernet jack leads to a switch port. If they have not limited the number of devices allowed on that port, you could connect a inexpensive switch, using a crossover cable (or a straight through patch cable that goes to an "uplink" port on the switch if it has it) and then you can plug more devices with straight through patch cables into the other ports. If they are limiting the devices, a router with built in switch ports could be used.

@Keith6783 Thanks Keith! Is a switch with built in switch ports more expensive then a switch without? By how much generally?

[Keith6783]

@AdrianAeleneiFilms

A small basic switch, with 8 ports is very inexpensive. If we add a router function to that, which includes a built in switch, it becomes more expensive, and add wireless to the router, it costs a little more. For a home wireless router, with an integrated switch and wireless support, the cost is between $50-$150 US. For an new industrial router with those same features they would start around $1000 and go way up from there.

Best wishes,

Keith

Finally someone intelligently explained the difference between the hub and switch.Thank you

That was awesome teaching. Thank you

Remember:

layer1: physical

layer2: data link

layer3: network

Thanks, good and clear video

Adding a hub, simply adds more ports to the broadcast/collision domain. So if more PCs were added (connecting to those ports), then yes, more potential PCs could be given access through the router, to the Internet.

@Keith6783 Thanks. Would a Hub Connected to the router LAN be able to give MORE computers access to internet too?
