Speed concerns and dropouts.

Hi,

I have a laptop (machine A) with a 802.11g wireless card (Linksys).
Also, a Netgear WGR614v2 wireless router. Another computer (machine
B) with a standard generic ethernet card, connected to the router.

If I ftp files from B to A, I get happy speeds of about 2.5MB/sec.

If I ftp a kernel from ftp.kernel.org to Machine B, it comes in around
600KB/sec.

If I ftp a kernel from ftp.kernel.org to Machine A, it comes in around
200KB/sec.

If I ftp a kernel from ftp.kernel.org to Machine A, using a patch
cable instead of wireless, it comes in at 600KB/sec.

So the problem as you see is that it seems like streaming Internet >
Router > Wireless is slower than Internet > Router > Wired, which
makes no sense in light of the great performance of Machine B > Router
> Wireless > Machine A.

Also:

Periodically I have to power cycle the modem. What will start to
happen is that apparently I am unable to make any new connections-
Existing FTP transfers will hum along fine and if I have a remote
desktop connection open it is not affected, but I can't connect to the
router or ping it, from either Machine A or B.

If anyone can offer any insight on either of these, I'd greatly
appreciate it.

- Aaron.

What's with the FTP to move files between machines? Why can't you use the
nromal file and print sharing services between machines?

Wireless is slowere than wired that's a fact.

In some parts, it doesn't get any more normal than FTP.

I suspect the 600KB/s which is a minimum of 4.8Mb/s transfer rate,
probably more like 6MB/s with overhead. If OOL support this speed, OK,
but something under 3Mb/s, 300KB/s, is typical of cable. Try
transfering an ISO image to each computer from a linux mirror at 3am and
see what you get.

The point is to eliminate as many variables as possible and try to
zero in on why the speeds are so different.

Wireless is slower than wired, duh. Yet FTPing over the local net
yields great wireless speeds. FTPing from the internet is faster over
a patch cable than wireless. So the wireless is not the problem.

Maybe I wasn't clear in my post. Net congestion is not the issue.
With my experiment, the cable modem has shown it can suck in data at
least at 600KB/sec. My local net can transfer at least 2,500MB/sec
via wireless. But data *from* the Internet *then* sent over wireless
gives a 66% drop in throughput compared to data *from* the Internet
*then* sent over a patch cable.

I guess you'll figure it out.
