MN-730 bad connectivity to LinkSys router

I've got an MN-730 PCI card in a very high-end machine,
connected to a LinkSys wireless-B broadband router, and my
connection drops at least once every 5 minutes, and
somewhere along the line drops packets like crazy (no perf
counters show this behavior however). I have four other
computers in this net using various non-MS hardware and
connected using ethernet cable or wireless; none has a
similar problem. All machines are running XP with latest
updates. The effects I see are:

- Very slow or no response browsing web pages;
- DNS resolution failures - failing to get a DNS response
to a resolution request, when all other computers on the
net can do so successfully;
- Occasional complete failure to connect to the net even
after minutes of waiting, e.g. when trying to sign in on
MSN IM;
- The broadband networking icon in my systray is orange
and says 'no connection to internet' even while the
broadband networking window says I'm connected

Things I've tried to resolve this:

1. Reset entire network multiple times, including DSL
modem and router;
2. Replaced MN-730 with a new one;
3. Updated all MS broadband software to latest (there are
no MN-730 firmware upgrades at this time);
4. All machines at latest XP service pack level;
5. Uninstall-reinstall of the PCI card and its software;
6. Ensure that all other machines in the net can browse
and work correctly during the sporadic failures of the MN-
730 machine.

At this point I can't figure out what to do besides paying
$100 for a new router that I don't want to have to buy.

Any ideas? Is there something between the MN-730 and
LinkSys routers? I saw one other gentleman's post about a
LinkSys wireless-G router having similar problems. Does MS
have any knowledge of interoperability problems between
the MN-730 and LinkSys routers?

Thanks!

Since you are using a linksys router, I would assume your network doesn't
use 802.1x authenication at all.

In Windows XP SP1, a change was made to this authenication method such that
wireless connections that had this option enabled would have its connection
dropped after 3 minutes if the connection could not authenicate against
802.1x credentials.

To disable 802.1x authenication over your wireless network card...

1.. Click Start, point to Connect To, click Show all connections, and then
double-click your wireless network adapter.
2.. On the General tab, click Properties.
3.. Click the Wireless Networks tab.
4.. Under Preferred Networks, click your home network, and then click
Properties.
5.. Click Data encryption (WEP enabled).
6.. Click the Association tab, and then click to clear the Network
Authentication (Shared mode) check box and the The key is provided for me
automatically check box, if they are selected.
7.. Click the Authentication tab, and then click to clear the Enable IEEE
802.1x authentication for this network check box, if it is selected.
8.. Click OK two times to accept the changes.


Also make sure the linksys router has the most up to date firmware
installed.

>I have experienced the same issue with this adapter
using a D-Link router and actually a MS wireless base
station as well. The only way I have been able to
resolve the issue is by using a different adapter--in
this case a Dell Truemobile.

Funny b/c I do use the MN-730 in other PCs in my office,
but in the higher end machine, connection is either not
seen or is dropped very frequently. I have not
experienced this problem with any other wireless
product.

Already did both of these. The LinkSys router's latest
firmware is from late 2002; I updated to this. I ensured
the authentication settings were off before the initial
post this morning (it has been off for the 3 weeks I've
been pursuing this problem). The post in fact took 3 tries
because of failures to resolve via DNS.
