JonnyBoy Posted November 20, 2003 Posted November 20, 2003 Ok, so I have been running 2 PC'c of a single adsl connection in canada for a couple of months without any real problem. I had to reinstall my OS a while back, and it caused issues. The non-reinstalled machine would connect and work fine on its own, however the reinstalled machine would not work properly for a while. would work slowley and intermittantly and caused the same symptoms on th eother machine too. rebooting non-reinst machine with other machine switched off allowed non-reinst machine to work perfectly on it sown. another reinstall followed and manually setting the connection restored a fully functioning shared adsl connection on both machines. So, it was time to reformat the other machine last week... same problem again. the now non-reinst machine works ok on its own, but with other reinst pc on...it has same symptoms. I'm confused as to why this may be..and what to do to solve the problem. This canadian modem doesnt let me into any settings like my UK device did (i.e. 192.168.1.100 for NAT, pppoe settings etc) Any light shed on this extremely frustrating problem would be gratefully recieved as i'm about ready to throw something out of the window!

Big Bad Ben Posted November 20, 2003 Posted November 20, 2003 There's a great forum here that helped me out enormously when I was setting up my LAN and broadband connection - give it a try. If you can't find any help using the search there, try posting - I was generally getting replies back within an hour. Hope this helps! BBB Quote
gregh Posted November 20, 2003 Posted November 20, 2003 how are you sharing the connection and what OS are you using? Quote
JonnyBoy Posted November 20, 2003 Author Posted November 20, 2003 ah, important info ommised! both on XP. adsl connection is with an adsl modem. 8 port network switch connects to the modem and both machines to the switch. Quote
Persil Posted November 20, 2003 Posted November 20, 2003 U cant share a internet connection with just a modem and switch... Only way to do it is using a router or using ICS (internet connection sharing) . From what u have said u dont have a router so the modem would have to be wired to one PC and that machine acts as the ICS server. Then u can eithier use a x-over cat5 cable betwen the 2 machines or since u have a switch you can just run some cat 5 to switch then connect other pc to swith and run the ICS wizard to connect to the ICS server (machine with modem) . Unless of course u may have a router modem combined (like what bt provide to business customers) then u could feed the signal from that to the switch which would feed both pcs (Router should assign ip via dhcp) Regards Persil Quote
JonnyBoy Posted November 20, 2003 Author Posted November 20, 2003 it is just a modem connected to a switch (switching hub) and it has been working for the past 3 months...we also had 8 machines back at uni connected to a modem thru one hub! I also had a 4port router modem and switch setup (same switch that i'm using now) at uni for another 8 people to share a different adsl connection. So..have i just been plain lucky? or should a modem - switching hub work? Quote
V7 SLR Posted November 20, 2003 Posted November 20, 2003 OK, I've been moving technologies around recently on my home ADSL system so here's the benefit of my experiments. First system: ADSL line -> single ethernet port modem/router -> 8-port switch -> numerous PC's This worked superbly for ages until I tried to get MSM video to work. The router was configured via a web interface on any of the attached PC's but would not let the video through. After lots of messing about I tried flashing the router and irreperably b*******ed it up. So I moved to the following system: ADSL line -> modem -> router -> switch -> PC's In messing about with this system I wanted to prove that the modem worked. It's an ethernet modem so I could plug it directly into my laptop and configure it from a web interface. I had to enable PPPoA between the laptop and modem in order to make an internet connection this way. Once that was working I connected the modem to my router. To get this to work I had to have PPPoE installed between the router and modem. If you plug the modem into a switch direct and several PC's are attached to the switch, in theory only one PC will "grab" the modem. That you've managed to get it to work at all is amazing because the router part of the system, whether it be a hardware router or software in your PC, carries the log-on details (id and password) as well as the protocols required. Again in theory, if both of your PC's had the router software installed (and by this I mean simple dial-up networking really) then one ought to grab the modem and not release it. I am amazed that you have got it to work at all to be honest although it is possible I have no clue what I'm talking about. My latest system is here A bit overkill, but it was fun getting it to work.

JonnyBoy Posted November 20, 2003 Author Posted November 20, 2003 well blow me.... i'm more onfused than ever now! Quote
V7 SLR Posted November 20, 2003 Posted November 20, 2003 I'm sorry. I was trying to point out (rather verbosely) that the situation you described appears impossible. However, it doesn't change the fact that you did have it working. If money isn't too tight, might I suggest a router anyway? It really is the solution. If not, then pick one of them and connect the modem directly to that one. You'll need a second network card in that PC to share the internet connection with the other one. I really can't understand how it was working. Sorry. Quote
westy Posted November 20, 2003 Posted November 20, 2003 Jonny, you have confused me too! Whats the model number of this modem so we can googlewhack it? If it connects to a switch then it should be a router type with dhcp/NAT and fancy whistles built in. But then to connect out would require you entering your username and password on the device itself normally through its web interface. Your PC's, have you given them static IP addresses (manual) or have they been allocated automatically via dhcp? If they start with 169 (I think) then they have been given automatic addresses by XP as it cant find a DHCP server. If they have normal private address such as your old 192.168 ones then chances are your modem is a router/combo. Quote

JonnyBoy Posted November 20, 2003 Author Posted November 20, 2003 d-link dsl-300g adsl modem generation II switch is a SCAn nway 8 port 10/100 fast ethernet switch It seems to be working again now! Quote
V7 SLR Posted November 20, 2003 Posted November 20, 2003 After the aggro of buying the place and the trouble I went to in cabling the whole house (and garage), I'm never selling. Fortunately, planning permission for extensions appears to be reasonably easy to get in this area, so we'll just expand. Quote
westy Posted November 20, 2003 Posted November 20, 2003 our house also has internet access throughout including the garage but we went for the wireless option Quote
