MR814v2 Netgear Works wired, not wirelessly

I just upgraded the firmware, but no joy.

The symptom is that a webpage with little data (google or others like
it) will load without problem. Searches on google come back fast.
But try to load a website with a lot of information and it bogs down
to the point where it might take 20 minutes to load the main.html
page.

Pings work. Whether dotted or FQDN. So I know I have connectivity.
Signal strength is reported as excellent and MPS never drop below 11,
certainly faster than the internet connection!

Replace the wireless USB network interface with a wired USB interface
and everything works just fine. The router functions as expected in
all respects with wired connections.

Checked everything I could check to confirm there wasn't some blocking
that was specific to the wireless IP address (Norton, Windows, Router)
in use.

Does this sound like something anybody has run across? I'm close to
thinking it is the wireless "portion" of the router and I'm hoping
that maybe somebody here will tell me I'm wrong and provide a quick
fix! I know, I know, wishful thinking.

Anyway, thanks in advance

Yes, I've seen this with an MR814. I don't recall if it was a V2 or
other hardware mutation. The problem was Centrino compatibility.
Solved with a firmware update. I'm not sure this is your problem but
it would be nice to have the latest firmware installed.

Also, you might wanna check your router MTU setting.

Also, from the Netgear web pile:
Intermittent Internet Connectivity or Connection Drops Transferring
Large Files
* Upgrade to the latest firmware.
* Connection drops every few minutes. Happens in various
situations, including with Intel Centrino adapters.
* Or, in older firmware, the NAT table can overflow when there is
heavy traffic between the LAN and the Internet. Overflows cause a
momentary interruption of connection.

It may also be a client radio issue. Have you tried your unidentified
wireless USB adapter at a hot spot or other access point to verify
that it works properly? If it does, the problem is probably in the
MR814. If not, then there's something wrong on the client end.

If still stuck, what flavour of Windoze are you using?
If XP have you installed SP2?

I think I already did that.

Will check and see. The article implies that if MTU is changed for
one computer, it should be changed for all computers, switches and
routers. Do you concur? Or should I just go with 1400 on the one
affected computer and see if that solves the problem?

I'll take it with my laptop down to Starbucks and see. My guess is
that it is working, but one never knows.

Thanks, Jeff. I have some work to do, obviously. XPHome-SP2 is
installed.

I'll post back if anything interesting develops, like it works!

Check the version to be sure.

No, I don't agree. Change it to the proper value on the router. The
client computers should negotiate the MTU value and set theirs
accordingly. Back in the stone age of TCP/IP, there were problems
with Windoze machines that would not properly negotiate the MTU but
that was long ago. You can test the client MTU using ping.

Don't forget to add 28 to the packet size for the real MTU size that
includes the header.

Assumption, the mother of all screwups.
Good luck.
