Slow performance on a DI-624 Wireless System

[Guest]

Archived from groups: alt.internet.wireless (More info?)

I have installed a D-Link DI624 wireless router to support my daughters
PowerBook and my old desktop PC. The desktop runs 98SE and has installed
in it a DWL-G520 card. Becuase of the location of the router and the
tower, I installed a standalone antenna to connect to the G520. The
wireless utility reports 70-90% signal strength, 802.11g mode at "54
MB/s" speed.

If I connect the PowerBook directed to the cable modem, I get 4 MB/sec
at bandwidthplace.com. Goint wireless throught the PowerBook I get
nearly the same 3-4 MB/sec. My friend brought his new Dell laptop over
and got blasingly fast performance. My desktop PC with the particular
card gets on 600-700 kB/s every time.

Any idea how what might be the culprit and how to spped up the desktop
bandwidth to the available 3-4 MB/s performance?

Thanks
Peter

Does your old desktop PC achieve 3-4 mbit/sec when you connect it to the
router with an ethernet cable instead of the radio?

That's a great question. I have not dragged it upstairs to get it in
proximity to the cable modem. Also, I would have to install an ethernet
card. Maybe I can do that today and narrow the trouble possibilities.
I'll try and post the results tonight or tomorrow. Thanks.

How old? What processor and memory? Many PC's are just too slow to
get full peformance from wireless (or wired).

OK. It's got a good signal.

3 to 4 Mbits/sec is typical of what you would get downloading via a
cable modem. Something is wrong with the desktop.

Yeah, the problem is probably an undersized RWIN (default receive
window size). Run the "tweak test" below and follow its advice.

"DRTCP" program works well enough for tweaking Win 98.

Well I tried my system with a 802.11b Wireless USB adapter - same speed.
I removed both the wireless adapter and the G520 PCI card, installed a
Linksys 100TX ethernet card and ran a 50' cable to the router. Same
speed about 600 kB/s.

Thoughts?

That confirms my guess: your desktop isn't up to the task. The usual
solutions (more memory, faster CPU, faster hard drive) will pep up your
machine some ... but not to "blasingly fast".

If you haven't done a careful search for malware running on your box, do so.

The only other suggestion I can offer is to invite the friend with the new
Dell laptop for another visit. Distract him and then throw a blanket over
the laptop. Perhaps he won't miss it.

Problem solved.

SUCCESS! THANK YOU so much. Used DRTCP and followed the suggestiones on
the tweak page and just got 4.1 MB/s! Great advice.
