Sorry about posting this again, last time I posted it in the same thread of someone having the same issue. I realized that this was against the rules and apologize...

So here we go again... :)

------------------------

The same thing is happening to me, it's affecting all the sites located on the same IP, i've tried ipconfig /flushdns along with release and renew...

Anyone know what's wrong?

I can't access my site / all sites hosted on that IP with more than one browser, also I have an email from my mail server on my site and I use thunderbird (mozilla) to get my mail but it cannot access it, etc.

I can't ping my site or the ip either.

When I use a webproxy I can access all of the websites though...


Please help! :(

Thanks in advance

PS- I've tried it on other computers on the network and it does the same... however outside of my network (and using web proxies) you can load the sites...

Given 's follow-up (removing the wireless password restored access) the problem is almost certainly a router-side configuration change that got triggered when wireless security was altered. ’s ISP-block idea is valid in general, but the pattern described usually points to features inside the home router rather than the upstream provider.

Check these router features and how they behave when security is changed: guest/guest-SSID modes (separate subnet or VLAN), AP/client isolation (prevents certain traffic from crossing), access-control or MAC/IP allow/deny lists, parental/content filters or URL blacklists, firewall IP/port filters, and any DNS or static-route overrides. Many devices apply per-SSID policies, so the same physical radio can behave differently when you toggle security or create a new SSID.

Practical troubleshooting steps to isolate the cause:

  • Test using a wired connection or a different wireless SSID to see whether the issue follows the wireless client or stays with the router.
  • Inspect the router admin pages for “Guest”, “AP Isolation”, “Access Control”, “Parental Controls”, “URL/IP Filters”, and any DNS settings. Enable router logging and look for blocked entries.
  • Run name-resolution and path checks to see where the connection breaks:
    nslookup example.com
tracert 1.2.3.4
# on mac/linux
dig example.com
traceroute 1.2.3.4
  • If a specific rule was applied by mistake, remove it, update router firmware, or perform a factory reset and reconfigure carefully.

Important: do not leave the network unsecured as a permanent fix. After diagnosing, restore WPA2/WPA3 with a strong key and then reapply only the needed policies. If feature names are unclear, consult the router manual or vendor support for terms like “guest network”, “client isolation”, “access control”, “IP/port filter” and “parental controls”.

Certain websites or site providers block a certain ISP because some users on that ISP (or pretending to be on that ISP) commits spam or spreads malware.

Okay so I found the problem, I put a password on my wireless router, then I couldn't access websites on the one ip, so then i took the password off and now I can... anyone know what it did???
