IE HTTP 400 Bad Request

ACWN said:

Thanks, Corrine :)


The only thing I changed recently was that I cleared out my cache and cookies when I was installing my new network - the tech and I were trying to get into the signal expander/repeater's page. I was having issues with it and he had me clear that stuff out to see if it was a corrupted file that was preventing me from accessing it.

Hi, ACWN.

Did the problem begin after the installation of your new network and the work you & the tech did? If so, that could be key to the issue.

A couple more questions -- since you are the only one in the household apparently having the problem, does it occur when you are the only one connected to the internet? Does it happen only with a wired connection or wireless as well?

In looking at the possibilities for this error in link that zigzag3143 initially supplied, I

For example, you may have a DNS problem. You can check this using a ‘ping’ test. A DNS problem may be caused by your ISP or may be on your own system e.g. in a ‘hosts’ file.

Perhaps it is due to a corrupted DNS cache. To clear the DNS cache in Windows Vista/Windows7, Click Start > All Programs > Accessories > Command Prompt. Right-click on it and select 'Run As Administrator'. Type the following and hit enter:

ipconfig /flushdns

You should be able to see a confirmation dialog window:

Windows IP Configuration. Successfully flushed the DNS Resolver Cache.

Started again. Havent gotten it on deviantart yet, but just got it on Netflix (was watching a movie, paused it to make lunch and when I started the movie again, the quality went to crap, closed the window and went to go back, got the error).

Installed Google Chrome and navigated to Netflix to see if I could replicate the error.

Didnt get the 400 error, but I did get an Invalid Code (or something like that) error. So I dont think its just IE...

Any one know what I can do?

Yes, before that it was fine. But I have cleared out my cache and messed with the network settings plenty of times before and its never done this.

No, others are connected most all of the time and I am strictly wireless. The router is too far away for me to be wired.

Well, I did what you both suggested - Capt. Sparrow, Corrine, and I dont know if it was one of those or the act of restarting my computer, but it seems to have worked. We shall see if it holds out.

We will keep our fingers crossed that the issue is resolved.

Wow, Linksys techs are idiots (most of them, any way). I went to them to see if they could help solve the issue as it started only after I set up the new network. They forced me to reset and reconfigure the router (told me to do something with out telling me I'd have to reset and reconfigure), and when I asked the tech that I had to call to get the router working again if I would still get the error after doing all this crap, he told me it was a browser error even though I'm getting it on two totally different browsers and even though it only started AFTER I set up this new network.


Well... we'll see if THIS works at all. Not holding my breath though.

Edit note: Hopefully whatever the Linksys folks have in mind will solve the problem. Following is what I was composing prior to seeing your post. I'll leave it here for what it is worth, particularly since it took me so long to remember where the link was on the MS site for the router placement.

It appears that what ever changes the technician made seems to have caused the problem.

However, I am wondering if the distance to the router is causing problems. I knew there was a page on the Microsoft website that illustrated good and bad router placement and finally found it. The image is at 10 tips for improving your wireless network. If you do not have a strong wireless signal, it may be necessary to get a wireless extender.

The other thought I had was to use the Windows 7 Network and Internet Troubleshooting Wizard. There is a tutorial here on how to open Troubleshooting.

I'm thinking that what the tech had me do caused it too. Hopefully having to reset and reconfigure fixed it.


I cant move the router because its the only place in the house that has a good cable connection. All the other cables in the house are broken up by splitters.

We already have an expander (my signal is always just fine when the error happens too), but thanks.


Troubleshooting didnt do anything, but I'm not having the problem right now.
