router, PC or modem problem?

[HappyCamper]

Hello I’m writing this in desperation as I can’t work out if I have a router, PC or modem problem.
My setup is VM BB XL New Black Modem and a Belkin N1 router hard wired Athlon pc xp sp3 Pbell quad core 4G Ram Vista 32bit sp1. wireless Lexmark printer, Toshiba satellite pro XP sp2 and a wii all working fine until just after new VM modem replaced old NTL silver one due to modem kept dropping connection to VM and trying to reboot it’s self. Fist few days all seamed to be working ok new PBell downloading at brake neck speed even the poor old tired Athlon with 512 Meg received a sped boost but then started to get unable to open page web site not found Bla Bla Bla on all pc’s. A ping of the DNS servers showed ok IP ok could still connect to VM pages new on’s not in history, but content taking long time to come down BBC and a few other sites but sites like google.co.uk would not load but going to ASK.co.uk and searching for google.co.uk would let me onto Google hence my thinking re DNS Server. Only other work around is down power PC, router and modem wait 5 mins reboot modem wait till modem online then router and finally PC this seems to work most of the time.
Things i.ve tried to do so far to resolve this are. Update router firmware Turned of router firewall left Norton on windows off made sure all units on same workgroup set internet options, Internet properties, Lan all un checked also tried checking automatically detect settings. Not sure if this helps but outlook some times will not connect to server reboot pc seams to resolve this. Just thinking of allowing icmp pings on router not sure what the security implications are. Any help or advice very gratefully received.

I cant be bothered with grammar police & the like but i had a wee bit trouble reading that block of text without highlighting the individual lines.Mabey my eye`s are just not what they used to be.

If you posted your modems config page though the networking guru`s here might be better able to spot something.

Also,have you tried just connecting the modem directly to your PC`s,without the router?Mabey try using different DNS.

also tried checking automatically detect settings

Unless you`ve set your router/PC`s to use static IP`s then you would need to keep that checked i believe.If i`ve even read you right that is.
I`m guessing that your not someone who might need his ICMP filtering turned off though so unless you know what your doing i`d leave it alone.

Xpod Thank you for taking the time to reply. As I said at the start of my post “I’m writing this in desperation�.
However looking back in the cold light of day I can see exactly what you mean.
That should teach me not to drink and type or proof read through smoke filled eyes.

Can you post the page that gives the power/signal levels as well (upstream/downstream)?

Hello Rob
The main problem i seam to be having is if I type in http://www.calltyco.com into my old PC (XP SP 3) connected to port 1 of the belkin router I can see the page but if I try from the new PC (vista 32bit) I can’t .
I’ve tried plugging new pc into different ports with no discernable results
Have also noticed new pc surfing very fast some of the time but even slow when browsing VM site.
As a test from the VM help page I clicked a link on my new pc and at the same time the same link on my wireless laptop. Laptop won the race by around 15 sec.
Same test Laptop V old PC, result to close to call.

First post: tl;dr
But from the title, have you tried with a direct connection to the modem for a period of time to see if you still have the issue?

And your power levels, SNR from the modem look just fine.

Thanks for the reply xocemp, I can't get the new PC near the modem but can’t help wondering, if some of my problems could be caused by the cable, so now trying to work out if I need a 5e or 6e UTP, FTP or STP patch 5M long

[Axegrinder]

Cat5e will do fine, make sure its not a crossover cable though, patch is what you need.

[HappyCamper]

Thanks but still a bit confused as to which type to get, UTP, STP, FTP
The adds on Amazon don't explain what each type is for,
or is it just me being a bit fick

You need Cat5e UTP straight-through (patch) cable.

Thank you to every one who has taken the time to try and help me out.
I will get new lead and post back results.
Thanks once again
