OS W7; Linksys Wireless-G PCI Adapter Model No: WMP54G

Doing ping -t 192.168.1.1 (router IP) for 3 hours.
About 3% packets is lost.

Same thing with wire - no lost packets.

Downloading Ubuntu in uTorrent - speed jump to 610 kB/s, then drop to 400 kB/s, and again - so I see horrible "saw" on graph - when wireless.

Same thing with wire - solid 610 kB/s.

Is it router or is it wifi card?

Check the router WAN setting. Make sure you are not forcing to 100 or 1000 speed.
I set mine to other than "Auto 10/100/1000" and got the saw tooth.

Also, torrents a notrious for that. Look for a big file (>200MB) (like the UBUNTU disk image) and download.

As for the wi-fi card, check your adapter Device Manager setting for Wireless N, make sure it is set to Auto.

1) "Auto 10/100/1000" - was set by default, I didn't change that.
2) UBUNTU disk image - that's exactly what I'm downloading, "ubuntu-9.10-desktop-i386.iso 725 MB.
3) Device Manager setting for Wireless N, make sure it is set to Auto - no such option in Advanced tab.

P.S. LED icons are VERY unclear. D-Link designers could do a better job.

P.P.S.
Compare charts:
Speed without router.
Speed with router on wired connection.
Speed with router on wireless connection. SAW!

I need to read better (ref. Ubuntu image)

What type of wireless adapter? Have you updated to latest driver?

Have you tried DLing Ubuntu via http? Same problem?
What about usenet (newsgroups), FTP (try from wired machine to laptop)?

1) I said in 1st post - Linksys Wireless-G PCI Adapter Model No: WMP54G.
2) I got latest Win7 64 driver from Windows Update.
3) http, usenet, ftp is useless for speed test, because only Torrent using DL bandwidth on 100%.

> 1) I said in 1st post - Linksys Wireless-G PCI Adapter Model No: WMP54G.
  Again, I need to learn to read!!!!! (old fart here)

>2) I got latest Win7 64 driver from Windows Update.
  I REALLLY don't trust MS drivers. If you can, and if it even exists, find the driver from the LinkSys website.

>3) http, usenet, ftp is useless for speed test, because only Torrent using DL bandwidth on 100%.
  On my system, FTP and Usenet are the fastest most consistent protocols. torrents are always
  up and down for me.
  My recommendation is set up an FTP server (http://filezilla-project.org/ - FREE!) on a wired
  desktop/laptop on your network.
  Connect to it with FileZilla client (again free) wirelessly from your laptop.
  This will:
  1. Isolate router and wireless adapter.
  2. Remove internet traffic out of the equation.

  If you still get a jagged graph, then adjust antennae or adjust laptop adapter (as much as you can).
  If solid graph, then you need to look into your DSL/Cable modem. maybe it needs replacing.

  If torrents are still a problem. Try a different source? I'm not well versed on torrents because they are
  always the slowest way for me to get what I want.
