Wireless throughput

I use a Linksys WRT54G on a 10mbits cable DSL line. Works well enough
on the wired side but the wireless side throughput is not quite up to
serving the maximum the connection can provide.

I am getting approx 600k downloads to wireless G centrino laptop,
compared to 1000k to 1100k on the wired side - no matter distance from
router, etc. I have changed router firmware to DD-Wrt and been tweaking
wireless settings but cant seem to get any improvement.

So, first of all I guess - am I correct in thinking my 54G should be
able to reach full download on my 10Mbps cable line?

If so, any recommendations for a wireless DSL router that will provide
the full wireless throughput?

Find and eliminate sources of wireless interference.
Try different channels.

Bits and Bytes again. Please pick one unit of measure.

I'll guess(tm) that you're getting 1000KBytes/sec, which is
8Mbits/sec. That's about what I would expect from a 10Mbit/sec cable
modem.

600KBytes/sec is 4.8Mbits/sec which is about what I would expect from
a decent 11Mbit/sec wireless 802.11b (not G) connection. So, the
first thing you check is what connection speed are you getting on the
wireless client? You didn't supply a maker, model number, or
operating system, so I'll leave it to you to find the connection
speed. If it's 11Mbit/sec, you have a problem.

Which EXACT version of DD-WRT? It's on the status page in the upper
right hand corner. Mine says:
DD-WRT v23 SP1-RC4 (05/12/06) std
(Oops. That should be SP1 Final, not one of release candidates).
The reason I ask is that some of the earlier versions had some nasy
bugs a few of which affected wireless thruput.

Also, what *HARDWARE* version of the WRT54G are you using? V1.1 has a
slow processor and had problems with anything over about 6Mbits/sec
thruput.

Yes. A 54Mbit/sec wireless connection should yield 25Mbits/sec in
thruput, which should be more than enough for your 10Mbit/sec cable
modem.

You have the make and model I would recommend with the firmware I
would recommend. I have serveral of these and they work just fine.
Try it with a known working laptop borrowed from a friend and see if
the problem is in the router or the wireless client. Also, try
dragging your Centrino laptop to someplace with broadband and see how
it works elsewhere.
