Installed .NET Framework 3.5 on Win XP SP3, And Now I Have No Inte

[anders_royce]

Can anyone tell me what is going on with my computer. I installed .net 3.5,
and I cannot connect to the internet with Internet Explorer or Firefox. The
weirdest part is that after rebooting my computer, I can connect for a few
minutes, but then get nothing but error messages in either browser, and
programs can't update. My wireless connection says it is fine. I have tried
the following:

Unistalled/reinstalled: .NET Framework, IE, FF (in various sequences)
System Restore (several different ones)
Connecting to a different network
Used a usb wireless antenna, and still no connection
Tried some random software that was supposed to reset all my wireless settings
Pulling my hair out, didn't help either

Can anyone provide some insight? Please?

Hi anders_royce,
The Microsoft .NET framework installation has got nothing at all to
do with your network connection settings. It is a collection of runtime
files needed only to support some programs that are based upon it. In XP, it
is not necessary at all, to have it on your system. I recommend that you
use the same process as you did when you first connected your computer up to
the internet, if you can, as you must have done this successfully at some
point in the past.

Thanks for the response. I will see what I can remember about setting this
computer up, but the trouble is that it pretty much hooked up to wifi right
out of the box. I just turned it on.

Since then, I have added a wireless utility from the manufacturer of my wifi
card, but I have already tried zero configuration and it is no different.

I also updated the driver at least once, but I can't see how that could be
it either. I already tried connecting with a different wifi antenna with a
different driver, and nothing changed.

It looks like this may come down to me completely wiping and restoring my
computer because I just can't wait much longer to fix this problem. I have
never done anything like that before, so if anyone could tell me what exactly
I would have to do, I would appreciate it.

I also would still love to hear any more suggestions on things to try that I
have missed.

Thanks

Hi anders_royce,
It sounds as if, if you can connect okay for a few minutes, that it's
perhaps your ISP that could be to blame. I'm connected via a wireless modem
dongle from 3three network and, just once, it stopped and would not download
any web material whatsoever even though Windows reported to me that I was
still connected. It turned out that the 3three network experienced some
"down time" and was back up the next day. When you can no longer see web
pages are you still "connected" (can you ping websites or yourself?)??
Open a command prompt (by typing cmd in the run box then press [ok]) and
type this command in:

ping www.google.com
ping 127.0.0.1

the first command will tell you if you are still really connected to the
internet, a successful "reply" if you are. The second command is a loopback
test and tells you if the adaptor you are using is functioning correctly by
pinging itself. "Pinging" is a term that simply means sending the most
basic packet of test data to a given destination to check the connection is
working.

Thanks for responding again. I will go try the pinging now, but the problem
is that it can't be my network because I can pick up my college's network
right outside, and I have the exact same problem there. I believe it has to
be some registry change, or wireless network setting that was altered. I know
you don't think it was the .net 3.5 installation, but I have never had any
problems of this kind, and installing .net was the only unusual thing I did
right before my computer stopped connecting. I also used a simple application
that was the reason I downloaded .net 3.5 in the first place, but I have
asked that developer and he says that the app does not make any changes to
network connections, and could not be responsible (He also agrees with you
that it wasn't .net). I just can't think of what else it could possibly be.

Thanks again

Also, yes, my windows thinks the connection is fine, tried repair
connection, windows said it was working. Tried another windows diagnostic
tool which reported no problems, but programs like my antivirus, etc. that
auto-update, cannot connect, and neither can the browsers.
I should perhaps mention that I am using a slightly unusual computer (MSI
Wind, atomprocessor), but I doubt that makes a difference.

Hi Anders,
I'm sorry, but my knowledge base is not that extensive
either. I was telling you how I found I had a similar problem. Since
no-one else seems to be responding then I'll hazard a guess. With other
connection problems, the advice here seems to be to check your
antivirus/firewall settings. Personally, if I couldn't get the connection
back, then I'd have to repeat what I had to do to install the connection in
the first place (i.e. reinstalling the broadband modem / provider's cd /
whatever). One last thing I'd be interested in though, what does it say
when you type in IPCONFIG /ALL at the Command Prompt? This will tell you
the state of the current IP address settings. And what was the result of the
"ping" experiment?
Sorry I can't be of more help.

Hello Tim,
Thanks for responding again. I have been working with a support guy from
Microsoft, and he had me try a bunch of different things, none of which
helped. His last instruction was to reinstall Windows. This proved a
difficult proposition because my computer has no disc drive (CD or DVD). So
before trying that, I decided to do a system restore to way back. I restored
my computer to last year, and now it seems to be working well. There are some
minor issues that resulted from the restore, but nothing nearly as
frustrating as having no connectivity was. Again, I really appreciate your
willingness to offer your advice.
Thanks,
Anders

Really very glad you got things resolved.
