Networking & wireless: network speed
network speed
by skeesey - 10/31/09 8:05 AMCurious problem,
Home network, cable modem then wireless hub
Wireless to laptop and desktop, 54Mbps and excellent signal strength to both systems.
Laptop gets 5.94 Mb/s download and 1.04 Mb/s upload
Desktop gets 0.14Mb/s download and 1.05 Mb/s upload
What is killing my upload on the desk top and how do I find it.
McAffe virus is up-to-date
Laptop is vista 64
Desktop is win xp pro
Desk top was faster a few months ago and then slowed down, dont know what might have been downloaded to kill it. I never ran a speed test before the problem.
thanks for any help you can give me in tracking this down.

Can you offer more details?
by Steven Haninger - 11/2/09 4:59 PM In reply to: network speed by skeeseyMake and model of router and wireless network card in the desktop would be a good start. As well, what have you already tried? The antenna orientation, proximity of the PC to interfering devices, channel being used, security setup on the router, etc. can all affect performance. It could also just be a wireless device going bad. I had one wireless device I tested on my own PC that would start a large download in a sprint but finish in a crawl. I never did figure out why other than maybe sitting on a basement floor wasn't a good location. Anyway, any details that can be offered are could offered are helpful.
thanks

System reports "excellent" signal strength and full 54 bit rate. That is why I did not think it was hardware. Tried to start in safe mode to see if something was starting that was taking bandwidth. When I start in safe with network I don’t get the wireless so I cannot test it. Not sure how to start it from safe mode. I have shut down everything that I know that I can.
It was working at a good rate then stopped so that I why I thought something was loaded that took the band width.
Any ideas on were or what to look for let me know, thanks again
Try this . . .
by Coryphaeus - 11/3/09 5:12 AM In reply to: thanks by skeeseyGo here http://www.dslreports.com/tools Run these test in this order:
Speed Test - write down the results
Tweak test - save the results
Download and install Dr.TCP and run it. Make the changes suggested in the Tweak test. Make sure the correct adapter is shown in the Dr.TCP settings.
Reboot.
results, doing tweeks next will let you know, thanks

download/use DRTCP .. (FAQ #578)
Read the tweak FAQ

Become pingable
if you need basic packet loss tests done
Check tweak FAQ

better, is this what I should see from 5meg cable? the laptop is still faster. can the desk top be as fast as the laptop?
The tweeks did not recomend any other fixes. Is there anything else I should do?
thanks
Remember this . .
by Coryphaeus - 11/4/09 5:38 PM In reply to: after tweeks: by skeeseyTime of day, server load, hops involved, all contribute to speed. Try the test at different times of day. If you still can't get what is advertised, call your ISP.
Did you hook it up wired and run the test?
by Steven Haninger - 11/5/09 2:24 AM In reply to: after tweeks: by skeeseyWe cannot use wireless as a reference when troubleshooting network speed issues. We need to start with the wired performance. If that is good, you have narrowed the search for the problem considerably. DRTCP is very old and was quite relevant with Win 98 as it was not optimized for broadband. XP shouldn't require much tweaking to get a good speed from a 5mbs cable connection.
