Some web pages won't load on wireless connection
I have two websites that quit loading on my wireless connection using the laptop. all others appear to work. If I plug in the router to my ethernet card on the laptop the two pages work. These pages will not work in IE 6.0 (blank page or default search page loads) nor Firefox 2 (Connection timed out The server at www.westford.mec.edu is taking too long to respond.)

I don't understand what is going on. I flushed the DNS cache but that didn't work. When I ping the site i get a response

C:\Documents and Settings\Dad>ping http://www.westford.mec.edu

Lets see if you can end up marking this one as solved

Actually, the way it works you (the thread originator) can mark 'solved' using the Thread Tools at the upper right, but we cannot.

Possibly a flaky adapter; probably a flaky router.

Suggest you reset the router to factory default settings and then reconfigure it.

Make sure you have the latest driver for the wireless adapter; uninstall the adapter and reinstall it.

Well, I can mark it solved.

I'm guessing it's not solved yet, right?

I think Terry is on the right track, I can't imagine what is going on here.

If you can find some other wireless machine (a friend with a laptop perhaps?), you could see if it's the wireless section of the router, or something in your machine.

I download the new drivers for the adaptor card, and rest the router to the factory defaults. Now I am having a little difficulity connecting to the router. I hate working on computers at night , it's been awhile since I set up this router. Probably has something to do with the security that I enabled.

this morning I connected to my neighbors wireless and was able to connect to those two web pages. So it appears that Terry is on the right track - flaky router. When I get home tonight I'll remove the security on the router and try again.

Check the firmware of the router .... Upgrade the firmware if it is not the latest One

Also Disable the firewall on the router if you have any

I think firmware Upgradation will solve your problem

Actually, disabling some of the firewall components of the router are more likely to fix this issue. If the SPI feature is faulty, it can result in certain sites stalling. Hard to imagine any firmware got out the door that will restrict certain sites.

Firmware is up to date, I check that a few days ago. I'll try disabling the firewall on the router, but I'm confused because the pages load when I am plugged in, just won't load for the wireless, unless it is timing out.

Hard to say, it seems like it's something in the wireless section. It's certainly an odd issue...

BTW, did you reset to factory defaults and reconfigure?

Check your DNS entries
I don't believe it's hardware related.

You are using Open DNS settings and I've found them to flake every now and again.

Have you tried your ISP's default DNS settings (or for that matter, your neighbors ) to see if that is the issue?

Yes I reset to factory defaults, reconfigured, and disabled the firewall on the router. The web page will not load. I was using open dns but since I reset to factory defaults I did not apply open dns. so I am automatically getting it from the ISP (Verizon - DSL). My neighbor uses Verizon also and I am able to connect through their wireless router. The web page that will not load is www.schoolnotes.com Normally not connecting would not bother me so much except this site has my kids homework listed on it and I can make sure that they bring the books home. Would the mtu setting have anything to do with it?

It's a long shot, but you can try reducing it. Try 1492 as a start.

it is something in my wireless router. Just connected to another one of my neighbors (I don't know about these people who don't secure their network ) and the site loads fine. New router maybe for access to one site, probably not.

MTU's
Before you manually play around with the MTU's in the registry, start by pinging with www.schoolnotes.com with a MTU of 1492 to see if you are dropping any packets.

ie: ping www.schoolnotes.com -l 1492

Proceed to lower the MTU's until you stop dropping packets by an increment of 10 or so. (drop the 1492 in the ping to 1482, 1472, 1462 etc.)
