Problem with internet connection

[matt819]

New computer, Dell Precision T1700. Wired ethernet connection.

Worked fine before move to new office in same building.

Problem: In both Chrome and IE (haven't checked Firefox, Opera, etc.), web pages don't always load on first attempt. Get error page with Reload button. Takes 3-7 tries reloading before page loads. Sometimes pages load in text format only. Happens on most websites I use, at one time or another, all name brand sites, including DU.

I have tried "everything." DNS servers primary and secondary are the Google servers: 8.8.8.8. and 8.8.4.4. No errors show up in Dell diagnostics. No errors show up in building's tech support's exploration of my computer or computer room switches. Since I'm the only office so far in the new section of the building, I don't know if this issue is due to the rewiring. Dell tech support confirms there is no hardware problem, so it's not their problem. They, and my local tech support guy, say it's software. But although I've loaded a variety of programs, nothing out of the ordinary. No firewall blocks on the websites I'm accessing. I use Avast anti-virus and have received no alerts. I'm going to run malwarebytes when I head home tonight.

Any thoughts on what I might try? Alternative DNS servers? I can check Firefox and Opera, but I really prefer to use Chrome. I suppose I should deactivate Avast and see what happens. Where do I look to see if the websites I'm having trouble with are somehow on a blacklist of sites by accident?

Thanks for the help.

1. Depending on the routers between you and the internet,

check to see if you need a new/different "gateway" or proxy server.

2. turn off your ad blocker browser plugins if you have any as well

websites are starting to add checks for ad-blockers and then they mess up the page when they encounter them (my theory anyway)

3. I'll try that

But I'm gonna be kissed if thats it. I hate ads.

4. If it is, just try some different AB plugins ... there's like dozens of 'em at least for FF ...

Last time I had a similar issue I just went from adblock to ad block plus or some such (it was not an upgrade version, it's two separate developers using similar names) and the problem was fixed & ads were still gone. I think it's a bit of cat and mouse thing ... the devs of the adblockers are much more nimble ... changing websites to detect stuff like this and 'complain' is a much bigger deal.

I think some devs of these blockers 'stay ahead' of the countermeasures ... better than others. If that makes any sense.

5. Try clearing the DNS cache

To clear your DNS cache if you use Windows 7, perform the following steps:

Click the Start button.
Enter cmd in the Start menu search text box.
Right-click on Command Prompt and select Run as Administrator.
Run the following command and press Enter: ipconfig /flushdns.

Some computers object to new web connections and clearing the DNS cache forces a clean connection.

6. Thanks

I'm doing without ad blockers at the moment. Page loading still a problem, but less so. Just cleared DNS cache. We'll see.

Thanks.
