problem with the internet connection

[darkassain]

i cant ping the gate way
but i can ping the other computers in the lan
and i cant ping dns ,google either

interesting...
what this computer connected to?
a hub, a switch or a router?

and also (as you said that you do static ip addressing)
did you try a higher ip (guessing since your subnet is 192.168.1.0 with your Subnet mask being 255.255.255.0) such as 192.168.1.192 or 252?
also can you try a different interface?

it always says destination host unreachable
and when im in ubuntu i can use the net properly and pin works fine

does ubuntu have the same IP info as the windows machine?

it seems that something is missing?
also if the routing device has any logging info can you check that...

Hi darkassain,

I think the router won't show any log of that machine, because it never connects or tries to connect to it. Well, at least not through IP4
This is the ip data he sent us.

By the way, he's offline.

your right i completely missed that he does not have a mac address...:sarc: (+rep for catching that)
hmm so might this be a driver issue (as the MAC addressed should be populated in ubuntu...)
that reminds me can you run ifconfig in ubuntu?

 

[SquonkSC]

Another thing I noticed:

Gateway and DNS server are different, and he has autoconfig enabled.
(and netbios, which he doesn't need)

Connection-specific DNS Suffix . :

DNS Servers . . . . . . . . . . . : 124.124.70.2
124.124.70.3
NetBIOS over Tcpip. . . . . . . . : Enabled

This means to me that next to a gateway, there must be a dns server too.

Plus he has autoconfig enabled, but he told me that all the computers have fixed IP in range up to 250 addresses.

If there is no device configured as DHCP server, and he tries to request an IP nothing will happen.

That's why he has to first find out how the other computers are setup to connect.


By the way, he got rid of Ubuntu, and is on Win7 now.

This is from a working computer with good connection.

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Marvell Yukon 88E8039 PCI-E Fast Eth
ernet Controller
Physical Address. . . . . . . . . : 00-E0-91-15-7C-16
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.68.27
Subnet Mask . . . . . . . . . . . : 255.255.255.0
IP Address. . . . . . . . . . . . : fe80::2e0:91ff:fe15:7c16%4
Default Gateway . . . . . . . . . : 192.168.68.1
DNS Servers . . . . . . . . . . . : 124.124.70.2
124.124.70.3


No mention of auto config, so it must be a fixed address.

He should put in fixed address and fixed dns in WIn7, than it should work.

At least, I think so.

 

[ganeshgun]

sorry we had internet connection from 8 am -2 pm disabled
ive already made those necessary changes like fixed ip and dns
as i told u its working in ubuntu with same ip and dns but not in windows 7(i have both os installed)

and i had gmail account is that enough???


@darkassain
my ip range as told by my seniors is only from 192.168.68.1-255 and ive tried different combinations but nothing worked
i was connected to a hub and others connected to the same hub are getting net even im getting net when im in ubuntu
until day before yesterday i got net normally in windows but from that day onwards suddenly it went wrong and nothing worked thought it was virus googled every running process from my taskmanager to makeshore that no virus is running but found nothing

 

[ganeshgun]

and when i made ifconfig from ubuntu this is the result i got

this confirms it...
malware may have wrecked with your machine...
im pretty sure that you dont configure anything on that machine (i dont remember though if hubs were smart enough to be able to assign you a ip address based on the mac address...:sarc
first see if you can reinstall the driver,
if that does not work then see if you can do a sfc /scannow and check...

next try to do a AV scan (if you have already done this, download any updates from another machine)

lastly try to do a system restore to a time when you didnt have this problem

if all of this does not work you might have luck with repair from the windows 7 dvd...
if all else fails backup your documents and anything of value reinstall windows...


the reasoning is look at the bold...
this does not look right to me because it seems you and your neighbors Subnet Masks dont match (judging from your subnet, yours should be 255.255.255.0 since this is a C class network and you are using the full 255 - 1 address space)
what you want to see in the ipconfig is the HWaddr that is boldned in windows...
if you see it as the physical address it should let you connect to other networks and consequently the internet...

 

[ganeshgun]

ive scanned it already but no effect(im using avg free)
and cant we remove this with any other anti virus???
or any other which scans and removes malware???

 

[ganeshgun]

for system restore i had only one restore point and tried it but didnt worked either

 

[darkassain]

for system restore i had only one restore point and tried it but didnt worked either

if you tried all the that i said then what you can try is force that MAC address..
go to the device manager and double click your network adapter...
then go to the the tab like on the pic copy and paste what you got in ubuntu

this: 00:00:6c:4a:d0:09
restart and check in ipconfig to see if it was able to stick the mac address..
if this doesnt work then you might have to reinstall windows..

 

[ganeshgun]

can u please give the detailed steps for changing the mac address please

 

[ganeshgun]

@darkassain
go to the the tab to look to at the pic that i have inserted

where is the pic???

 

[ganeshgun]

thanks buddy
by doing mac spoofing its finally working[]

 

[Ram666]

I have the same problem with the internet in windows 7 (no internet acces), when I restart the PC in safe mode work fine.What is the problem?

Damn, .. great solution.
The spoofing of mac address never crossed my mind.

Read this entire thread from the beginning.

Do the IPCONFIG/ALL in command prompt and compare it with the one at the beginning of this thread.

Then read all until the end and you'll find the solution.

Good luck

cannot detect wireless network isatap error code 31

so for the last few weeks i have been unable to detect networks with my pc. I get the error code 31 on the isatap adaptor. ive tryed removing it and also turning off IPv6 but still no luck im debating about just reformating and upgrading to 7 but im not entirley sure it will resolve that issue. In other fourms ive heard that this usually occurs after a corrupt instalation of the os so im hoping 7 will fixing it.
i have an xbox main pc and laptop runing of the router now and am trying to add my new pc to the network. its definitley in range of the router so the only thing that could be causing the issue is the adaptor. is it totaly nesscary to have this? and if not is there somthing that can take its place?
i have an hp pheniox SE with vista sp1 an athreos 802.11 a/b/g/n card and a linksys wrt54g router
