No internet acces windows 7

Hello!

I really need help, because i already tried everything.My internet was working fine but one day i turned on my pc and there was a yellow triangle in right corner bottom.Then i reinstalled lan driver and it worked.But this problem repeats and even reinstalling lan driver doesnt help any more.I reinstalled whole windows and internet was working but only one day.Now sometimes i turn up ym computer im lucky and it works but often im trying everythig, restarting computer many times but still not working.Sometimes when i start computer there is yellow tiangle but after 30 seconds it disapears.In safe mode with networking internet works.
I called my internet provider and they couldnt help me.They said i can try with reinstalling lan drivers or they said it may be burned my network card because of any storm.Please tell me that this isnt true if internet sometimes works.


Please help me and thank you.

Sounds to me like you have someone using the same IP as your computer is using. Do you now if DHCP is enabled on your computer for the networking card? If it is then make sure it also is on for the DNS settigns.

When it does not work, try going to a command prompt and typing: ping 127.0.0.1. This will test network connectivity to itself.

If you have more then one computer in the house there may also be a problem wiht dhcp as ahniliated suggested? You can make sure you are on auto dhcp by going to network and sharing center, change adapter setting, select your adapter and right click and hit properties, select IPv4 in the white list of items, click properties, make sure auto dhcp and auto dns is enabled.

undee ipv4 properties is enabled obtain ip automatically and obtain dns server address automatically. And yes we have my computer connected by cable and 1 more, plus laptop on wifi and mobile devices on wifi.Other devices all work.I'll try ping 127.0.0.1 when it doesnt work..


thanks for now!

OK i rebooted 2 times my comouter.First time i tried to type ping 127.0.0.1 to cmd but after 30-60 sec after windows started the yellow triangle disapeared.Second time there was also yellow triangle and test ping.

Reply from 127.0.0.1: bytes 32 time<1ms TTL=28

Ping statistic:
packets: sent=4 received=4 lost=0
Approx. round trip
Minimum= 0ms Maximum= 0ms Average= 0ms


I bought new ssd 2 and installed windows because i want my pc to boot up fast and not waiting 1 minute to connect . It was working nice at start and before ssd i didnt have any similat troubles. And usually i turned it off in the evening and next day it doesnt connect at all.

Hi. Where can i enable dhcp and dns settings?

He is refering to what I asked you to check:

You can make sure you are on auto dhcp by going to network and sharing center, change adapter setting, select your adapter and right click and hit properties, select IPv4 in the white list of items, click properties, make sure auto dhcp and auto dns is enabled.


It is possible that your computer is being assigned an IP that is arelady in use on the netwok. Do the same procedure for all windows devices on your network (check both wired and wireless adapters if the device has both).

Ok i had to go under advanced options...There are ip settings where dhcp is enabled.Under DNS is checked first option so i think its enabled.It says Append primary and connection specific DNS suffixes.


Thanks for helping
