Dhcp leasing problem

[Kloppstock]

Its kind of hard to choose the rightest under-forum for this but

I have a problem with my Internet and computer
i loose my connection to internet for short intevalls after some random time online, all file-sharing and net browsing goes down at the same time..and then wakes to life again after a half minute

I have saved my router event logg, and i know exactley whath the problem is

..but i just don't know what is causing it
As you can see here my router seems to be periodically deleting the WAN IP address leaving me offline for 30 seconds to a minute before it leases a new IP

18:22:04 (since last boot) DHCC IP address 87.227.102.174 deleted: ok

18:22:35 (since last boot) DHCC IP address 87.227.102.174 (255.255.255.0) set on intf Internet: ok

I allso cauth this smooth criminal in Wireshark, looks like this, ICMP Protocol all of a sudden

the problem is..that im not bright enough to understand how to use sniffer
softwares in deep and accually understand how to track after additional info ore sett up optimal settings

I have confronted my ISP about the overall problematic, thei say thath thei can't see any problems on their side and have no heard complaints of anything similar.
and heres a wery important thing to know!

This ISP i have currentley..i have only hade them 1 month now.
AND with my previous ISP this problem has looked exactley the same as now..for 1 year now (and i switched ISP just to get ridd of this i thauth)
and...i got this computer...yes...1 year ago
so i think you know what i mean

with my old computer this was not a problem, and i didnt even have a router back then..just a standard modem with a dynamic IP
now i have a router with a permanet IP (if i understand it right)

and there is absolutley no change anyway..so i can altaeast after alot of research exclude all forms of possible differences in IP adresses ore ISP relatad problems, router settings

so what is left then?
this computer...everyone stand and point at it
something unknown makes my specific computer to force "DHCC leasing"
some form of stealth settings perhaps? some form of conflicting software?
(no spyware!)

I have a speedtouch 780 WL router (and thei say i dont need to update this Firmware)
I have Windows XP Home Edition SP2 (with thath connection limit optimizer patch installed)

Hijack This Logg ("invalid file"...i cant attach and post it??)

Motherboard - ASUS P5WD2-Premium (Updated)

Intel Chipset 955x Express Chipset (Updated to latest IU)
Memory controller:82955X

Intel P4 3400 MHz 2 Gb Ram

If anyone here is familiar with my computer modell, specifications ore if you understand how to track any Network Sniffer loggs in deep, i ask you to please help me in any way

You might try reinstalling the TCP/ip stack and /or replacing the NIC

[Niqd]

Buy a new network Interface card (NIC) and install it. and/or

Go the properties of "Local Area Connection" (Control panel, network connections) uninstall/reinstall Internet Protocol TCP/IP.

The dsl modem is reporting that the line state is down. The symptoms you describe suggest the possibility that your DSL modem is losing sync and is having to retrain, and hence the periodic random outages you experience.

You may have changed ISP's, but if there is a condition on your line, changing ISP's won't make any difference. If there is a device on your phone line interferring with the DSL signal, they would not be able to detect it unless the phone company ran tests on your line.

If it is your computer that is having the issue, then when the outage occurs you would ping the dsl router and it would fail.

I would troubleshoot for DSL connectivity first.

Hi

we accually have a house alarm attached to the phoneline..however its offline seens 5 years i dont know if that crap can react negative with my connection if its not online?...and i therefore can't decide its therefore worth do de-attach the whole **** from the phoneline? cause thaths alot of work........for my dad
other than thath..there is no seconday equitment!

Yes my poor ISP have done some for of tests and thei say thei cant see any problems...but perhaps it is as you say here..its my phone company who would see problems ISP test wont see

sorry my moderate english..did you mean i should try ping it when the dropps appears?

try removing the alarm, removing any satellite receiver phone jacks and replace your dsl filter.

[electric_dragon]

Kloppstock, if that alarm system is still connected to your home phone lines, chances are that the signal is being weakened as a result. I would recommend that you get this system disconnected. You should then check to make sure that there is a filter present in all of the jacks that line leads to.

[Kloppstock]

yes removing the alarm..is one solution im gonna try when i have excluded some moore things..

like i noticed just recentley thath im not sure thath i have installed the latest firmware for my network card
cause i have allways been unsure how i shall install the driver, after failing? i still buyed the fact thath the salesman told me thath Win XP will detect this card and work without anything install

but now i gonna do it fully here

look here
http://www.sweex.com/producten.php?s...l=715&detail=d

this is the unpacked RAR


what i have done before, is just right klick on NETRTS5 and schosed "Install"

is thath enought..ore should i have done something moore with other files? (i have not found any install instructions)

thank you/Kloppstock

If the alarm is wired like mine is, it taps into the phone line before the telco service entrance, and so can interrupt the phone line. You need to rewire so the alarm is no longer wired into the phone line.
