    home network problems

    ello all

    big big pain in the ass time, my home network has gone mad.........

    this morning no one on the network could access the net or each other. cable modem and router were reset and now i can access the net. good start i thought, but no one else can access the net or each other and all have 'limited or no connectivity'?

    i have run home netwwork wizzard on all 3 computers, reset cable modem and router, all to no avail. i also reset the dhcp service.

    my ip was always the normal 192.168.0.xxx, with the router assigned to 192.168.0.1 . now my ip is 81.103.63.8 and god only knows what the router's is as i cant get on it through my computer [dispair].

    i would use static ip's but i dont know my dns server is...

    any ideas would be greatly appriciated thankyou

    norton internet security on mine, others dont use a software firewall.

    the connection isnt shared through my machine tho, all machines are fed it off the router. coulld firewalls still play a part? i have tried turning mine off, but no differences there.

    I had lots of probs a while ago with zonealarm, machines couldnt see each other when it reverted to the free version. Just a guess really.

    cheers for the suggestions flibb

    i just got off the phone to d-link and the (very helpfull) man there thinks it's b0rked, doh. he rekons it's acting as a switch to my computer and theat the 'router' function is stuffed , could be related to the power surge last night that blew a lightbuld from its fitting! surge protector time me thinks.

    can anyone reccomend a good quality 4 port router for cable broadband? wired, pos with wireless or gigabit (so i have upgrade options) if they're cheap.

    thanks

    ouch - fun and games. it's running in non-nat mode - the router dump tool may work with your router http://shadow.sentry.org/~trev/dsl50x.html and you should be able to dump all of the settings to a text file. you should still be able to check the gateway address in your ip settings and see if that will access it (doubtful)
    I can thoroughly recommend linksys, as their new firmware seems really solid - even the old firmware on my wireles-b linksys cable router is rock solid after over 2 years - just a few little updates to fix some niggles.
    i've also got a really old one at my parent's place which is taking care of my servers (hey, they've got cable - I've got adsl - they've got much more bandwidth and telewest doesn't mind) which went EOL about 3 years ago (gives you an idea of the age) - never had a problem with it... but the Dlink 504 here in my flat gives me no end of grief. I have to hard reboot it at least once a week, and it drives me bonkers. I've also got a netgear which is also pretty cool

    I also use a D-Link router - I would advise against buying one, it has to be reset regularly, sometimes several times in one day. My guess is overheating, but whatever the reason, it should not be happening. Go for something else more reliable.

    doh, after i was singing d-link's praises so recently too

    ive been looking at this one and this one too

    just wondering what the real difference is? seems to be the firewall... is it worth the extra? i do value security highly but i run a software firewall (norton) sooooo is it worth me getting a good hardware one on the router and not running the software one, or saving the money and just running the software one, being sesible and buyuing the dearer router and running a software firewall...? so many questions

    also, would you guys mind explaining what VPN is and its benfits (briefly of course as i dont want to keep you up all night) as it seems somewhat more expensive and i dont know whether to consider it or not?

    cheers again

    you probably won't be using VPN - if you do, all it does it create a VPN tunnel over IPSec - most routers don't fully support this - i.e. they can create a VPN tunnel from the gateway to office vpn - but not guarenteed from the client to the office vpn.
    The "vanilla" router just allows you to define the ports which are in use (pretty standard) where the other one with firewall proactively scans incoming traffic and applys the rules in order (on top of the router functionality)
    I'd go wireless - especially since you're running cable, as it gives you better options going forward. Less to configure than if you bolt on an AP.
    Most of the new ones support both B + G modes, as there's no real benefit in running A (unless you've got loads of DECT phones and microwaves which will degrade the signal of b+g modes)
    I like this one - scotty
