Hi,
I applied a cable internet for my appartment. They send me a cable modem. I
connect my laptop to modem and browse the internet without problem. The
problem is if my roomate try to use her laptop, She has to reset the modem
(turn off 1-2 minute and on again) to get it work, and then if I use it I
have to reset again.
I also try to connect another router to this modem for all of us but noone
able to get to the internet thru the router which connect to the modem.
Is there a way for us to able to connect to internet without reset the modem
(just plug in cable and use).
Why do we can not use internet the same time thru the router even the
connection status show very fine( Packet sent and received over thousand)?
I am very appreciating for your help. Thanks

sounds like cable company is blocking your signal your computer is the one
they have registered or the one they first installed .i live in iowa and
mediacom cable has done that to me they wanted five dollors amonth per extra
computer .do a ip release then shut down unplug cable modem and router then
when you restart plug modem and router back in

Your PC is getting the IP address your cable company is sending you. So when
your roommate connects it won't work because its not the same PC. I would
purchase a Linksys router and then you just have to plug a cable in to the
router when ever you want and your on, no problems. Better yet a Linksys
Wireless router then you can do it from anywhere in your Apt.

Good Luck

Some cable ISPs only connect to a specific MAC address (each piece of
hardware has its own MAC address). Sometimes, this is fixed as the MAC
address of the first PC to successfully connect -- in which case you
have to call the ISP to reset your connection if you change equipment.
Other times -- and it looks as if this is your case -- turning off the
modem briefly allows the connection to reset.

If this is the case, I'm not sure why your router wasn't recognized if
you had turned the modem off for several minutes before connecting the
router. Are you sure you configured the router correctly otherwise?

However, many routers have a feature that permits them to "clone" the
MAC address so that they appear to be the original PC. Try this.

Connect with your PC. Make sure that you really are connected to the
Internet. Open a command prompt window (start > run > cmd [click OK])
In the command prompt window that opens up, type
"ipconfig /all" [without quotes] [press enter]

Among other things, you should see a line like this:
Physical Address. . . . . . . . . : 00-10-DC-D2-77-F2

That is the physical address (or MAC address) of your computer. Write
it down.

Now, read the manual for your router, learn how to clone its MAC
address, and set the router's MAC address to the MAC address that you
wrote down. Configure the remainder of your router's WAN connection
entries appropriately. The router should now connect to the Internet
and you should be able to connect both computers to the router and get
to the Internet.

If you have problems, be sure to include the make and model of your
router in your next post.
