This is the response from the Linksys to PHP:
HTTP/1.1 401 Authorization Required

This server could not verify that you are authorized to access.
Either you supplied the wrong credentials(e.g., bad password),

Since you can sniff traffic, can you inspect the HTTP response as well?
Perhaps your LinkSys web server software is asking to upgrade to
HTTP/1.1 (since "upgrading" your request's declared version appeared to
solve it).
If not, it might at least reveal some sort of HTTP response code that
is causing problems for PHP.

The problem seems to be the HTTP/1.0
If I telnet to port 80 and manually send the headers below, it all
works.
GET /Status.htm HTTP/1.1
Authorization: Basic eDpjYW5hZGFv
Host: 192.168.3.1
User-Agent: PHP/4.1.0
Maybe the Linksys does not like the HTTP/1.0 line.

For those who can't read hexdump/ascii together:
CURL:
GET /Status.htm HTTP/1.1
Authorization: Basic eDpjYW5hZGFv
User-Agent: curl/7.9.2 (win32) libcurl 7.9.2 (OpenSSL 0.9.6b)
Host: 192.168.3.1
Pragma: no-cache
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*
PHP:
GET /Status.htm HTTP/1.0
Authorization: Basic eDpjYW5hZGFv

I used a sniffer to compare teh HTTP request from PHP (which fails) to
the one from CURL (which works). Here's it:

cURL can handle redirects on pages with password protection. PHP cannot
do that yet. There must be something special about that page since I
can read pages protected by password under my Apache server with no
problems.
As a temporary workaround I suggeest you use cURL extension until we
can find a publicly available site where this problem can be
reproduced.
