Networking question...

[Disco Dan]

A little nerdy... but stuck none the less.

Just switched over to wired broadband from wireless and I have struck a small networking problem. I have a wireless router and now the DSL Modem from my ISP, everything works just dandy. However I cant access the management page of the router when DSL modem is connected to it. Works just fine plugged straight into the back of my mac, but cant work out how to access it with modem attached?

I just type the I.P address into my browser to access it normally. Tried a few variations etc but just get some Apache server page which is default I.P of the macs built in web design software.

Probably really simple, but it has me stumped... I hate networks!

what ip is your mac?
what ip is the router?
what ip is the modem?

perhaps some static routing is required in the router

http://192.168.1.1/ - what I type in to get the management page - at the moment that gives me the DSL Modem page.

Picture below is what happens if I type in 192.168.1.2

thats most likley a machine on your network
aka your mac machine

[Cajun]

okay the problem be dealing with ips of some kind.

since the adsl modem/wireless router most likley use different ips,

you want to set your wireless router to have ip 192.168.1.2 cause your modem will take 192.168.1.1

Your best bet is actually put them on different networks... so leave the modem as it is, and change the ip of wireless router to something like 192.168.5.1 and adjust dhcp server range accordingly (eg 192.168.5.100-192.168.5.199)
Then you should be able to access both networks fine.

Leave WAN or internet side of wireless router on auto/dhcp

Your ADSL router should be acting as a dhcp server, giving IP addresses to machine that connect to it.

You could have a couple of issues.

1. The adsl router is acting as a dhcp server and so is the wireless access point.
2. You are connecting to apache, but not to the correct website alias.

Hell .. i could go on for hours.

here's the skinny, from my angle. If your internet is working fine, from both cat connected machines and wireless, than your issue is more than likely going to be that both the adsl router and the wireless one are acting as dhcp servers.

I would recommend changing you internal network to a class A .. (10.x.x.x) as your adsl router is no doubt going to be a class C (192.x.x.x), doing that will allow you to separate your internal network from the adsl router.

oh yeah, how do you have the network set up?
Modem > Wireless router > pc
or
Modem > switch as well as router into switch?

HUH?


phone line ---> modem --> router --> iMac

[Delphinus]

phone line ---> modem --> router --> iMac

Where router > imac = wireless?


My above instructions should work

[Jabez]

HUH?


phone line ---> modem --> router --> iMac

Phone line (ISP network) --> modem (private nw ie 192.168.0.0/24) router (2nd private network ie 192.168.5.0/24) --MAC.

Private networks can not be the same.

[Disco Dan]

ahh cool as...

so how do I change the I.P address of the router?

Its a "netgear" router, 4 ports + wireless

I can get into the setup page via the web browser, but I will have to unplug the woosh dsl modem to do it.

...last time I tried that I stuffed up the settings and took me ages to get the smegging thing working again!

[Delphinus]

you shouldn't need to unplug anything... just type in its ip address to your browser... can you set your mac's ip yourself?
Router IP might change and leave mac on wrong network unable to connect...

if I can.. I dont know how :cry:

I cant get into the router page, only the dls modem page... so I cant change the IP of the router... if I unplug the modem, then I can access the router page and change stuff...

[Delphinus]

Are you using a switch/hub at all?

What are the IP's of router and modem?

[Disco Dan]

got it sorted.. finally... managed to change the IP of the router, reset everything and rebooted computer etc... gave it a minute to detect the new network settings and it all worked fine.

Cheers for the help peeps :yes:
