I’m trying to add broadband to a small network which previously worked fine. Where the modem is now, there used to be a cable that connected the 2 routers either side. When all IP’s are manually configured (dhcp off), everything is how it used to be, including no internet (even though it has to go through the modem/router!).
I’ve included 2 diagrams showing how it’s setup. Please help!!! The aim is to have internet access on DKS (MINILAB), SHOPCOMPUTER, ATHLON64-2GHZ, JAMESCOMPUTER and ACER5050. It’s also essential that JAMESCOMPUTER can see shared folders on DKS (MINILAB)!

Hmm I think I’m getting confused between routers and switches!
Come to think of it, I’m pretty sure that they’re all switches (except the modem)(
[/QUOTE]
so, presumably the modem is a combined router & modem & switch
switches usually have only RJ45 connections & a power connection[ot]i killed a switch by connecting it to the wrong PSU[/ot]routers have RJ45 connections & 1 or more RJ11 connection (an old 56k modem connection from modem) & obviously power
[QUOTE=thomas]
In that case, they’re switches! Just out of interest, why would a router have an RJ11 socket?
[/QUOTE]
routers have at least 1 RJ11 socket to connect the router to the microfilter which connect the router to the phone line (exactly like the connector on an old 56k modem)
i assumed you were using separate modem, router & switch because your diagram showed a separate modem nowadays routers usually come with integrated modem, switch & built in firewall (Windoze boxes still need a software firewall) my new router i’ve ordered also has a FXS VoIP port (to connect a standard telephone) & a FXO port to enable that telephone to work through the router over a standard PSTN automatically when your broadband is down
i think you may be best to start with a new network topology diagram, shall i attempt a rough one for you ?
BTW: can you list exactly what you have (make & model) if you what a rough topological diagram
Edit:[ot]i thought you knew more than me about networking, presumably you lack the practical stuff, correct ?[/ot]
Yes a diagram would help, although I cannot get make and model numbers until next Saturday (it’s a Saturday job!). The talktalk modem is a huwei 520s, but that’s all I can remember. DKS (MINILAB) and the 2 kiosks cannot have their network settings changed, it took a network expert hours to get them setup apparently , and I don’t want to break them!
ok, what you / they have is an Huawei Echolife 520s - wireless router & 2 switches, i’ll get GIMPing your network topological diagram
BTW: it would take me hours because i don’t fully understand networking, so, bear with me please, but a network expert like AT wouldn’t take that long
the only reason i don’t fully understand networking is: i only have my single home system to play with & only have other forums & wiki to rely on, but, i’m always learning & willing to try new stuff, anyway, i’ll get started with GIMP
turn DHCP on on the router connected directly to the net because if the router has DHCP on it acts like a switch whereas with DHCP on it will fully enable the router, then it may just work
Edit: if it works, it is because enable or disabling DHCP (very basically) turn routing on or off, obviously it does far more than that, but try it first
Edit:
yes, becaus it was acting like a switch, enable DHCP & it should act like a router
, and I don’t want to break them!
