Specs: Mac OS Tiger, p4 3.4 ghz, 2gb ram
in my apartment i can access the internet
through my main bedroom (bedroom 1) on
both my mac desktop and pc laptop but when
i move to my second bedroom (bedroom 2) i
can't connect at all- is there a way i can leave
my laptop in bedroom 1 and move my mac
desktop to bedroom 2 and connect to my
laptop with my mac for internet use- this is the
only way i can get internet- i can't get any new
ethernet cords or new routers so please do not
suggest a way, only answer if you know how
you can do this- without buying anything- im
pretty sure there is a way because i used to
share the internet connection from my laptop
to my xbox with xbox live-

No ethernet cables and can't purchase any hardware??

Going to be impossible for this unless you have wireless in both system that are same band.

You never shared anything wirelessly at 1000 ft. Or is that just a made up number for bedroom 2 from bedroom 1?

It would help if you told us what both pc and mac were connecting to.

its not that the distance from the bedrooms is 1000 ft its just
built very awkwardly and to wire it decently i would need a very
long cord- my imac g4 running tiger and my acer laptop running
vista can both connect to the internet in bedroom 1- can i have
my imac in bedroom 2 connect to my laptop in bedroom 1 to
share the internet connection all wirelessly? otherwise someone
has mentioned a "repeater"? can someone find a link if they
know what im talking about because i have never heard of one
and dont know what kind to get

For your PC to provide a link to the internet for your MAC, your PC will need two NIC's and to be setup with Windows internet sharing.

I assume from what you have said that your current internet connection from bedroom 1 is wireless, so your PC has a wireless NIC.

If you don't have two wireless NIC's on your PC and you can't buy any hardware, then I don't see how you can do this. But if you have an ethernet connection in bedroom 1 and your PC can use its ethernet NIC to make the connection to Internet then there is a possible solution.

If your PC can connect to the Internet by ethernet (i.e., hardwired), then with Windows internet sharing enabled you can use the PC's wireless NIC to connect to the MAC.

If this is the case:
1. Can your MAC link with your PC on the wireless NICs. If both communicated to the internet through wireless then it is likely that they can connect to each other (although not definite). Both will need to be set to the same channel and use a peer to peer protocol.
2. Can a MAC communicate to a PC using Windows internet connection sharing protocol (I don't know the answer to this - but you might, or someone else on this forum may know).
3. If the MAC and PC can link and communicate, can they link between bedroom 1 and bedroom 2, (i.e., no steel walls/1000 feet separation).

If you can get a second wireless NIC for your PC, such as a USB NIC or a PCI wireless NIC then a fully wireless solution may be possible, but it depends on 1, 2 and 3 above.

Hope this helps.

Problem with two wireless cards in one system is interferance from each other. Wireless repeaters or bridges need the orginating equipment, your pc, to support bridging. This is why linking wired from pc to router is advantageous. No wireless cross talk at the pc but you get the benefits of connecting to the access point wirelessly.

Hi Wanderer,

Although two wireless cards in one PC will have some interference issues, it is still possible.

I have tested a laptop with two wireless connections, to two separate wireless routers and both work - (on different channels) and the second one connected (a USB wireless device) connected and obtained its IP from the DHCP on the second router while the first wireless connection was active. Both report 54Mbps connections although I can't test actual throughput. Pinging both wireless NICs from a different PC suggested that there was some delay when both wireless NICs were active, but only on one NIC, so the issue may be in Windows OS rather than a wireless contention.

As a result I think that the basic concept of the bedroom_1 PC with two wireless connections is workable. There may be some interference and reduced throughput, but it is better than no connection. I can't test throughput rates on my setup.

It would be better for the bedroom 1 PC to have an ethernet and a wireless connection, but I don't think that this is possible for Sidious 999 from what has been posted. I would be happy to be proved wrong on this. Hopefully Sidious 999 will tell us whether an ethernet hardwired connection to the Internet is available in bedroom 1.

Sidious 999 said that no new hardware was possible, so repeaters/AP's are out.

Apart from the 'no new hardware' issue, a repeater could be placed in bedroom 1, and both the PC and the MAC could connect to it. A cheaper home wireless router could be used instead, but the throughput falls due to the single channel connection. I don't know enough about repeaters to be be able to comment on this setup.

In the configuration I suggested as possible, Windows provides the bridging between the two NICs, and AFAIK there is no reason why two wireless NICs won't link (but I have never tried this setup, so I may be wrong!)
