Connection timed out on some sites

Can someone please help me? Im able to get on the internet, but I cant connect to some websites. The message says "the connection has timed out" and the site is taking too long to respond. My computer has a linksys AE1000 adapter connected to a linksys wrt150N router. I think it has something to do with my router because my sisters laptop cannot connect to the same sites when she uses my internet connection, but is fine when she goes to her house. I've looked at other people's forums with similar problems and tried their advice, but it didnt work. I've tried looking up my host file and it only had the default statement. I've tried pinging the websites and it would fail and said it timed out. I also did the ipconfig/flushdns command and nothing happened. I changed my MTU to manual and 1500, and I checked if my firewall was affecting it and it wasnt. Im completely stuck and have no idea what to do. Can someone please help me? =(

Did you try to bypass the router and connect straight to the modem?

My computer's ethernet plug doesnt work due to a power outage. I think it messed something up since it cannot read the connection from the modem. Thats why I had to connect through an adapter.

Oh, you mean wireless adapter?

Wasn't it cheaper to simply buy new ethernet card?

Turn the computer off.

On your router, you'll find a pinhole marked "Reset".
Keep pushing the hole, using a pencil, or a paperclip until all lights briefly come off and on.
Restart computer and check for issues.

I couldnt find a place that sold my ethernet card port. I have a pretty old computer.. about 6-7 years old right now. I also already tried resetting the router by unplugging it and also pressing the red button. I had to change the password on the router and i also changed the MTU to manual with 1500 as the number. I did as you said and I still cant get on those sites.

Post a traceroute to one(or more) of those sites.

Open up command prompt(start -> run -> type cmd and press enter) -> type "tracert www.thatsiteyoucantaccess.com" (without the quotes) and post back the results.

The results were:

1 1ms <1ms <1ms 192.168.1.254
2 ads1-71-52-1.pns.bellsouth.net [98.71.52.1] reports: Destination net unreachable.

Trace complete.

It does the same with other sites too..

Any computer store will cary PCI ethernet card for about 15 bucks.
It'll fit any computer with free PCI slot.

Would that fix my internet problem then? Well, I would still need the router since my sister uses a laptop and she would like to get on the internet too. Does it seem like the router is the cause of the problem?

That, I don't know yet.
If you get an ethernet card, than we'll see, if wired connection gives you same problem as wireless.
If it does, we can bypass a router and see, if it works through modem only.
So, it'll give us more info to play with.

Thats a problem inside of your ISP's network. Give them a call.

Whats an ISP network? Is it the internet provider?

Yes. In this case its Bellsouth/AT&T.

Okay thanks. I've connected my sisters laptop to the modem directly and found out that its the modem or internet provider so Im talking to them right now. Its already been over an hour that I've been doing common troubleshooting with the person, but they couldnt figure it out and now Im on hold to talk to the advance group... I hope they help and fix my problem!!! >_<

Okay... I got transferred to the advance group and told me they couldn't help me unless a pay $99 for a fee and $15 after every month or $120 as second option... Is there any possibilities that someone can help me without having to pay that? They told me the problem has something to do with either the firewall or some port on the modem. Can someone please help me with this? TT-TT
