We have a wireless network between 3 or 4 pc's. During the day we can see 3
or 4 other networks, one of which is strong (35%). During the day the
network will hang, restart ... . Last night when all the other networks were
down the network was solid. Have tried changing channels, changing the
location of the wireless router. Does anyone have any helpful suggestions.
TIA

the 2.4GHz band is pretty saturated in urban and some MDU locations.
have you tried ALL available channels? is yours set to G only (which
may help some with performance).

do you have the latest firmware for your router? which version
router and what hardware rev do you have?

Do not believe netgear has that option.

We have been having the router check for updates & it says there are none.
Perhaps i should check their site.

what exact model netgear router do you have?

wgt624

if there is no version # listed it is the original or V1. or there
may be a version #. go to
http://kbserver.netgear.com/products/WGT624.asp for both a firmware
check and manuals which would tell you how to set to G only.

Interesting, the router asks if u want to check for updated firmware to
which we replied yes. It replied no updates (or words to that effect) don't
you believe it, when we went to netgear we found several latter firmware's.
Got the latest  so will see if that helps.

I don't have your original question,...but judging from the subject
line,...I really doubt a firmware update is going to fix an interference
problem.

In a home environment,..the most common source of interference is the
microwave oven and the cordless phone which all work in the same (or near
same) GHz Freq Range.

In an apartment or duplex you could even have the next door neighbor with a
microwave right on the other side of the wall from your device,..so it would
be only 8-12 inches away.

The latest firmware makes this statement: 'Fixed wireless connection drop
under noisy environment'. That is one of the symptoms we had.

Ok, but there is a difference between just general noise and having it
"mowed over" by something on the same frequency in close proximity,..no
firmware can solve that.

Anyway, I'm not saying don't update the firmware,..that should be done
anyway,...I'm just saying watch out for things like microwaves and cordless
phones.

that is typical of some of these routers..

Hi
If the interference come from other Wireless Networks, and you already tried
changing channels try to use a Wireless utility that can be configured to
connect only to your SSID.
Otherwise, there is nothing too much that you can do about it beside buying
New High Power Hardware.

The possibility being that one of your neighbours is running a WLAN with SSID
disabled, I'd advise you to run NetStumbler and get a reliable environment list.
Letting it run over a couple days would be a very good idea.

To add just a little bit to what others have already posted --

Consider the possibility of coincidence:  depending on where you're
located, sources of interference *other* than nearby wireless networks
may also be turned off at night.  As Barb Bowman noted, there are a lot
of other users of the 2.5 MHz band, including microwave ovens, some
cordless telephones, and some wireless intercoms.  Thus, your
interference source may be closer than a neighboring access point.

Using a tool like Netstumbler, as Chuck suggested, is a good idea.
Although there are 11 channels available (in the U.S.), for practical
purposes, only channels 1, 6, and 11 are far enough apart to prevent
most interference.  Thus, if you discover that the high power access
point is on channel 1, use channel 11 (and vice versa).  If the high
power access point is on channel 6, consider figuring out who owns it
and asking them to change to 1 or 11.

Although Netstumbler probably will tell you if an access point is using
802.11b or 802.11g, I don't know if it will tell you if the AP is using
some version of "draft" or "pre-" 802.11n.  Some early implementations
of draft 802.11n (from about a year or so ago) were notorious for
completely disabling nearby 802.11g networks.  (See, e.g., this article
from June 2006: http://blogs.zdnet.com/Ou/?p=247). It may be that the
only way to determine this (and certainly the only way to fix things if
this is your problem) is to get in touch with the owner of the offending
access point.

Finally, I really doubt that your Netgear router lacks a "g-only" mode.
  What model is it?

You may need something like WiSpy.

Chuck -- an interesting and amusing thread, particularly your first
comment (not to mention the youtube clip).  ;)

i think the question was 'all available channels'

To which you replied, "Do not believe netgear has that option."

That doesn't make sense as an answer to whether you had tried all
available channels, but does make sense as an answer (even if incorrect)
to whether you had set your router to "G only."

In fact, the WGT624 can be set to "g only," 108 Mbps Turbo g only, or "g
and b."  See page 4-4 of the User Guide (this is for the version 1 User
Guide; for other versions, the page is different but the answer is the
same). ftp://downloads.netgear.com/files/wgt624_ref_manual.pdf

Will setting the mode to g only help in your situation?  I don't know
(and I doubt it), but your router definitely has that capability.
