DNS error

[Guest110]

When i right click on my lan connection and try to repair it i get a windows could not renew ip address error..... Whats going on here then please:eek:

[Tortanick]

Try rebooting your router.

Also open a terminal and type ipconfig -all and post the output.

how do i copy from the command screen please

[Guest110]

:decision: and how do i reboot the router. HELP ....please and will it hurt

[Seth]

:decision: and how do i reboot the router..please and will it hurt

Maybe...cuz some boot back.

Unplug the power to your modem. Plug it back in and wait 30 seconds. If you have a router, then do the same to the router after you reset the modem. Now restart the computer. It should be fine now.

[Tortanick]

to copy from the command screen right click it, click mark, then drag select the text, right click the highlighted area to copy.

As for reboots, I usually unplug mine then plug it back in a few seconds later, but it may be difrent for you're router. Just check that reset button isn't a restore settings to factory defaults ;)

Right i rebooted the router.. no luck
cant mark and seem to get the text in cmd i select it and right click but paste is greyed out

what now fellas

[Guest110]

Oh now what i cant sign into messenger

[Tortanick]

well maby your ISP's DNS servers arn't working. Try useing diffrent ones.

Go to settings, network connections, then chose the one you get to the internet with.

Open it, click properties. scroll down to TCP/IP and click properties. Select use the following DNS servers.

4.4.4.1
4.4.4.2

those should work

[dbarrow]

Check router menu for ROUTER STATUS or connection status.
Make sure it shows it is connected to the modem and obtains an IP, subnet, DHCP and DNS server.
If not, reboot the modem.
Watch modem lights and make sure it is connecting.

Is this cable, DSL, dial-up?

[Guest110]

I have rebooted the router and still no luck.. dns error and it is broadband that shares the phone line

[dbarrow]

Find your instruction book for the router.
The router menu is accessed from your browser by entering an IP, ie: Netgear 192.168.0.1 logon is Admin and PW you set (default 1234)

DSL by phone?
Check with your ISP for setup info and checking your modem.
On a cable modem, you can again access through browser with an IP ie: Motorola SB5100 is 192.168.100.1, shows connections status, signal and SNR levels as well as connection logs.

If you can obtain specific info on your modem and router, visit DSLreports forums for your specific IP provider and you can often obtain necessary anwers to your questions.

Thank you.. perhaps it is a fault with my network. Seem to have lost the laptop and access to files upstairs from time to time. I can connect to the internet which is the main use..
Thanks for your help:D

Update when i try to use this fix (http://www.updatexp.com/dns-windows-xp.html)


http://www.freewebs.com/blackmirror111/ip.JPG

[dbarrow]

This brings back faint memory of something I read through in the MSKB before with failure to flush/rebuild DNS cache.
I believe it mentioned a fix. I recall doing something similar a long time back. Search MSKB for DNS, network repair, flushdns, winsock ... foggy memory... something about resetting winsock. I know there was an answer in there somewhere.

Have you tried:
Device Manager, uninstall the nic and blow away the connection, uninstall the network.
Ignore the hardware wizard finding the nic again on reboot and use the networking wizard selecting machine does not connect to the internet. That will blow away all network settings.
Reboot, let it install nic again, run network wizard and set up the network again.
That may clear it by replacing everything from scratch.

i will try that and let you know.. I have spent over an hour trying to fix it..I asked for help somewhere else and got a sarcastic reply ..
thanks

[Guest110]

That wont affect my broadband connection if i do that as it is very dodgy at the moment

[Guest110]

I have had the answer from a friend at you know where Bless her Julie

start run cmd and
REG ADD HKLM\SYSTEM\CurrentControlSet\Services\Dnscache /V Start /T REG_DWORD /F /D 2

link is here (http://www.jsifaq.com/SF/Tips/Tip.aspx?id=10577):eek:


perhaps someone with more pc knowledge can tell me why it worked ???

[dbarrow]

care to explain to us what that key does?

[Guest110]

I have no idea but not only has it fixed the dns cache issue it has restored my network to full capabilities.. sorry i dont know:D

[Guest110]

Well it did work for a short time and now i am getting cannot renew your ip address contact person who manages your network.. i have conracted myself and i still am no wiser

[dbarrow]

You have ruled out HARDWARE?
Is the router talking to the modem?
Have you rebooted the modem and the router again?
(correct order, reboot modem until it lights up indicating connection, reboot router until it connects to modem, reboot machine until it connects to router)

Can you PING your router? (or open the router control from your browser)
Is the router STATUS page showing an IP, SUBNET, DNS server, etc info as correctly connected and talking to modem?
Can you access the modem info page/logs from your browser?
Can you PING and TRACERT any URL/IP?
Take the cable out of the router and go to modem directly.
Can the machine connect to the web now?

Faulty modem, faulty router ... likely a hardware connectivity problem.
Call your ISP and have them check to see if your modem shows as connected on their end. (don't know about DSL but with cable, I can call Comcast and have them look down at my modem and tell me if it is properly synced with them, signal and power levels, send test pings to it, etc. You have to rule out the modem as the first problem area)

thanks i will check through your suggestions

[Guest110]

the only thing i can see disabled is U pn P on the router page

and what should the lease time for ip be it is set at forever at the moment

[dbarrow]

The lease term is usually established by your ISP.
You can get into the router, you can see an IP and lease,
therefore: your machine is talking to the router, the router is talking to the modem.
Now, can you ping (try Ping Plotter) anything above the modem?
Are you showing an IP, DHCP server, DNS server, subnet mask delivered from the modem?

Is your machine to router set up dynamic or static IP, ie: get IP automatically or 192.168.0.2 etc.?
(failure of REPAIR function on machine end network connection would indicate it is not receiving an IP from the DHCP in the router).
When it goes down, does your machine have an IP and all related info?

Again, I am leaning towares hardware as in bad router, modem, nic card, but you have to determine where that failure is when it isn't working.

When i lose my broadband connection it could be an hour or so before i can get back online.. This never happened when Wanado was provider,, taken over by orange and their support page is crap

The router is a Belkin wireless networking starter kit 125 mbps

when i changed from dial up to broadband they sent me a usb speedtouch modem
however it kept getting knocked off and it broke so i bought this kit to network 2 pcs and a laptop
I dont think i really understand networks that the problem
Rebooted router again
Have download pingplotter what do i do with it please

[dbarrow]

Stop... back up... you are chasing ghosts...
This is a web connectivity issue.
There is a logical progression to figure out where the problem is.

Start at the machine.
Your machine(s) should be connecting to the router and ipconfig should show each machine with an IP, subnet mask, default gateway.
If the machine isn't talking to the router, problem is in the machine.

Machines should access the network and see each other.
If they all do, problem is not the machines or the router.

Router should see and talk to modem.
If you can access your router menu, your machine is correctly talking to the router.
The other machines show correctly as attached devices.
In the router setup menu or status menu, you should see its connection to the modem. It will have a web IP (the IP assigned to the modem), the default gateway to the ISP, the DNS and DHCP servers.
If the router menu is not seeing all these, the router is not talking to the modem or the modem is not responding.
Only way to determine, reboot the modem then the router and see if it connects. If it does, suspect the modem.

Check the modem, are the lights all lit showing it connected? If not, the modem is down. If that is the problem and you reboot the modem and it comes back up, suspect the modem. Some are crap and fail routinely. Swapping them out with the ISP is not uncommon. (I once pitched a ***** about one that was flakey and a Comcast truck showed up next day with a brand new SB5100 I still use)

Is it a line problem?
You have to research the modem and find the IP to access the modem menu, ie: Motorola SB5100 is 192.168.00.1/logs.html
If you can access this from your browser, problem is either modem or connection.
Logs and status in modem menu show signal power, signal to noise ratio. You have to know what 'norms' are for these as being out of range on either results in dropped connection. Log file contains connection errors. Read this.

Now, having verified that the problem is ABOVE your machines and router, it is up to your ISP to troubleshoot your connection. Call for a service tech to come out and test your lines and connections.

These connection issues can be very intermittant and sporadic. IF you have an idea what you are talking about, and have done all your internal testing, you can usually get very fast results from your ISP in fixing any external connection problems.

Work on the problem from your end up to the modem.
When things are working, use the DSLreports tests for speed and line tests, packet loss, etc. See if there is something between you and your ISP causing the problem and have that ready when you call for service.

I can't tell you anything about DSL but with cable, I can make a local phone call and have them look at my modem from their end and measure signal, SNR, etc. and tell me if anyone else in the neighborhood is down or having problems.

I am currently chasing an overnight only loss of connectivity which I strongly suspect is something Comcast is doing with maintenance as I have seen mention of something similar on the DSLreports Comcast forum.
Network is up and working, modem shows connected, but router has lost subnet, default gateway, DNS and DHCP servers.
Because, after a brief disconnect, you have to reboot the modem and then the router to aquire the numbers, it is difficult to pinpoint because the modem is online, has re-connected, but now the router needs a reboot or release/renew to re-aquire. Drives me nuts as all the numbers and tests are correct.

[Guest110]

Phew a lot of information there.. thanks for typing all that for me.. will start at the top and work my way down

The modem and router are one i believe but i have this listed under modems softv92 data fax modem PCI Slot 2

[dbarrow]

The modem and router are one i believe but i have this listed under modems softv92 data fax modem PCI Slot 2

Data fax modem in PCI slot is not your internet modem.
That should be connected to a phone line to send faxes or for a dialup.
Your modem that connects to the web should be external and connected to the router.

Have you called your ISP tech service line and explained to them you are having a connection issue?
May well be worth having a tech come out...
At the least you can resolve your external connection status.

i have tried phoning orange but i was put on hold for 30 mins and give up in the end.... so my modem/ router is all in one then

I am so sorry for this.... just hope i dont have too many problems lol

[dbarrow]

Is this a unit they supply?
Do they have a local tech support number?
(ie: Comcast has an 800 number that goes to Canada and they can't do squat but there is a local service center where I can go direct to a level 2 tech in minutes)

I would seriously spend some time getting through to tech support and pitch a ***** about connectivity issues until they fix it or .... go cable!

Over here... people say Verizon DSL is SOL for tech support. People carp about Comcast cable but I have always had most excellent tech service above and beyond... providing you know what you are talking about and bump it up to the right levels.

Same works for Verizon. Explain your problem and what
you have done to resolve it as simply as possible, don't let
them BS you, stand your ground, ask for a supervisor -- and,
if necessary, the supervisor's supervisor! That's how I got
them to concede it was not my AV, firewall, or insufficient
RAM at fault. That's how I got them to straighten out
incorrect billing.

The first tier of tech support is often on-the-job training for
a new employee. They read from the company's tech bible
and give you non sequitur replies to your questions or suggest
inappropriate solutions (i.e., reformat!).

As a last resort, politely threaten to vote with your
feet and consider another broadband supplier.

BTW, off-topic comment, but politcians behave and
should be handled the same way. .... :)

Unfortunately i live in a rural part of the UK that they deem not worthy for technology such as cable. In fact we a part that cant get Free view TV as well.
I bought the router/modem myself and up until my IP changed hands it was OK.
Its annoying but thank you all for your suggestions and i hope to get through on the phone eventually:D

[dbarrow]

I would look at that unit as the problem. ISPs frequently upgrade their services by means of firmware downloads that change the modem configuration (provisioning). As this may not be a "stock" modem compatible with their settings, I would replace with whatever they offer and buy another router to connect to it.

Went through that with a PCI slot cable modem before.
They changed things in the system and made it obsolete.

I spoke too soon lol

Still cant access pc upstairs

havent got time at the minute so its not a problem:high5:

[dbarrow]

Ok, you have me totally lost and confused.
IS this a network issue from one machine to the other or does it involve Web connectivity?
Isolate and separate between the two.
Can both machines access the web?
Can both machines see each other?

Can #1 see #2?
Can #2 see #1?
If #1 can see #2 or visa versa but it does not work the opposite way around, suspect a firewall issue (blocking)
Start by working this out with all firewalls OFF.

Use your Ping and IPCONFIG to determine that both machines have the correct information showing and can see each other and the router correctly.

When one machine drops off, determine why and where it has lost connection.
Does it still see the router?
Does it still have the correct IP and subnet and default gateway?
Does it access the web?
Does it show as connected in the router?

Check "attached devices" in the router menu and make sure it is showing both machines connected.
IF not, work from the router to the machine not showing
(router problem) Try static IPs to the router.

Let us know your results.

[Guest110]
