Hi,

I'm trying to access some sites that I always access (since I did not have this linksys router), and now I could see linksys is blocking some sites, and when I try to reach  them out of my linksys net, with my 3G modem, I can reach this sites... what might be happening? How to fix this issue?

Thank you

Check the internet access policy in the router config. You should disable it

Hi,

All the policies are disabled yet, and the problem persists.

Any other idea?

Thanks

1. Did you try rebooting the traffic?
2. Are there any other network devices in the layout?
3. Check the browser for a proxy config

Hi marcoloppo,
This could be something simple like a DNS issue or an MTU issue.
Can you access the sites by IP (simply ping the site from a working connection to find out the IP, this works for all sites which don't run off a shared server)
For some more troubleshooting, can you give any specifics to the sites you're trying to access and which are blocked?
You're saying the Linksys router is blocking the sites, as the WRT54G is just a simple NAT-router, what happens if you connect your computer directly to your modem?

Hey,

Bingo!!! When I put the ip of the site I'm trying to access I get the access even in my linksys router net, the URL is: www.meuaeiou.com.br and the IP http://75.125.24.221/

So how can I fix this?

Thank you.

Hi marcoloppo,
Probably the simplest way to fix it is to manually set DNS servers in your computer. You can use the ones assigned by your provider or public DNS servers like the ones from OpenDNS (208.67.222.222 & 208.67.220.220)
To add these, go to the TCP/IP properties of your networkcard and enter them, you can leave the IP, subnetmask and gateway settings to be automatically assigned.
Regards,
LucF
