Windows 7: No internet access

This could indicate power surge, did you have any power surge protectors in place? If no are you able to test an alternate NIC? This can help determine if this is a software or hardware problem

If not then are you able to test the machine on another network at all? Possibly a friend or relatives?

Yes all my electronics plug into a surge protector. I don't have any NIC's laying around, i suppose I could go and buy one.

This should have prevented it, Don't buy another NIC as of yet... If I am to suggest anything that would be a reinstallation of Windows over purchasing a new card.

I think a clean install will be the answer, I was really hoping to avoid this. I have a lot of stuff on the PC.

Do not reformat+reinstall Windows over this.

Search > CMD > Left Click 'Run As Administrator'.

IPConfig /Release
IPConfig /Renew

This should force the DHCP to 'Enable' (your DHCP being Disabled is the problem here) and also to force the ISP DNS to resend the 24 hour lease to your modem along with the new DNS packets that it needs to connect to your ISP's servers again. This has happened to me many times during a power outage (even also when Verizon was performing routine maintenance that knocked us off a couple of times, same thing happens either way... DHCP doesn't get its DNS packets and lease = no connectivity until it does), where I otherwise would have had to wait out those 24 hours (or even days when it would still neglect to resend these credentials automatically as it should). It was as simple as the IPConfig/ Release and Renew 9 out of 10 times. I have found that this is easier and more often successful using an XP system, however (does not always work on 7).

On the rare instances that doesn't work, then you need to call your ISP for support. I am quite sure that reformatting and reinstalling Windows is not going to resolve this.

If you absolutely don't want to deal with your ISP and everything else has failed... then you need to try to reset your modem/router. It will go back to defaults and so yes, you will have to reconfigure it again through its admin GUI (and this is providing your ISP allows you to do this without having to call them. As an example, Verizon forces you to because of their security measures... the router will lock you out until they break it's lease and renew it anyway so you might as well just call your ISP and let them handle it from the get-go).

Good luck.

EDIT: If this storm involved lightning and your WiFi was on... your modem is NOT surge protected because of the coaxial lines, which are unprotected. WiFi particularly when broadcasting its SSID attracts electrical storms/lightning like nothing else (which is why WiFi should always be turned off during storms or better yet, just unplugging the whole system and coaxial lines also off of their power source until it passes. Better safe than sorry). Your modem could have easily fried in that storm, and it simply needs to be replaced to resolve the problem. Again, contact your ISP for support. They can fix it. Leave Windows alone.

EDIT 2: One relatively simple way to determine if your modem/router is still basally functional or not is to put 192.168.1.1 into your address bar on the browser and put in the admin and password for its admin GUI. If it takes it, its working. If it doesn't then it is the modem/router. And again, if you don't know what the username and password is for this, you'll have to get it from ISP support. But if you do, great. Try this too.

Huh?

IPconfig /release and Renew only obtains a new IP address from the DHCP server as well as renews the current lease for that IP address. As you can see there is no DHCP server from the OPs IPconfig settings because the address was entered statically. Microsoft Corporation


You will also find that the OP has run the batch file located on this thread which already contains those commands - Network Posting Tips

IPconfig is not related in any way to an ISPs settings, IPconfig only affects the local NIC of the host machine. DNS packets do not exist, DNS servers store URLS to IPs and are sent to clients by UDP packets. They are in no way shape or form related to DHCP. As shown from the OPs IPconfig the DNS servers are not relevant to this issue since other machines connect fine even when testing with Google's Public DNS servers.

Again, if you look at the OPs IPconfig you will find that the default gateway is 192.168.1.254 therefore that is the routers ip address and not 192.168.1.1

Hi guys, think it'll rain?

Going over your CBS log I'm seeing a lot of "Cannot repair member file", and windows code-integrity calls.

Just a sample:

Unless NoelDP can pitch in with a patch to this and then re-run the SURT with another SFC scan, the best I can offer is,

Have you tried a safe mode re-start with "last known good configuration" or a system restore to before the lighting strike.

I have ran SFC as well but it states errors can't be fixed.

I also tried a automatic repair. I will attach my CBS log, hoping someone can read it and advise on what to do next.
There has been some discussion of your thread as to the statement I've highlighted.

Have you tried to run the SFC scan at least three times or more with restarts in between?

See Note after Option Two step #4:

Note   Note
  • If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 or more times to completely fix everything that it's able to.
  • If not, then download and run the 32-bit (x86) or 64-bit (x64) System Update Readiness Tool for your same installed 32-bit or 64-bit Windows 7, restart the PC afterwards, and try the sfc /scannow command again.
  • If still not, then you can attempt to run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.
  • If still not, then you can use the steps in the TIP box in the OPTION THREE section below to manually replace the files that SFC could not fix.
