wireless problem

[Dan Conrad]

Have a SMC7004wFw router home network with one hardwire and two wireless
units -- were initially running off smc cards. Recently purchased a new
labtop that has its own internal wireless (intel 2200BG). Initially
successfully worked as unsecured hookup -- found connection and worked
well. Then internet ceased to work -- have packets received but not
sent. States that unit is connected and good signal, can hit repair
button and will reconnect -- but internet still not working. Properties
of wireless hookups shows microsoft client, intell wireless connection
agent, File and printer sharing, Q0S packet scheduler, AEGIS protocol
--IEEE 802.1x (v3.1.0.1), and TCP/IP.

If I use the hardwire hookup from new computer -- to same router, works
fine. What is happening? Thanks.

What IP address is it giving you? Is it assigning one in the 192.168.*.*
range? Is there a firewall blocking outbound packets?

Yes ip address is as you indicate -- how can I tell if a firewall is
blocking outbound packets?

I'm not well versed in networking at all, perhaps this is way off base.
I've had an ongoing problem with my home network since I switched from a B
to a G router. Two desktops that are connected via wireless adaptor would
lose the connection every day. At times, just reconnecting worked but at
other times, there was "limited" connectivity - the two desktops could see
the network but could not surf, receive email, etc. I found the problem to
be a defect in the router. The router supports 64 & 128 WEP and also WPA.
With no encryption or 64 bit WEP, the two desktops connected with no problem
and did not lose the connection. With any higher encryption, connectivity
would be lost at random times and there were times when re-establishing a
connection would not work.

Unless something more fundamental is amiss, it sounds to be like the lost
connections are due to signal loss. You need to be keeping an eye on your
signal strength. If the signal is interrupted at all when encryption
handshaking is taking place, the connection will fail. Wireless connections
are constantly going up and down in signal strength due to interference. If
your signal strength isn't strong to start with the addition of 128bit
encryption to your tcp packets can cause problems not seen if no encryption
is used.

Perhaps that is the the problem with the router - not enough signal
strength. A new one is one the way. There is also a laptop that has never
lost the connection and is a further distance from the router than the two
desktops that lose connections. Also, I have a wireless bridge attached to
an X-Box on the bottom floor of the house (all PCs are on the top floor) and
that has never dropped a connection. It's strange, hopefully the
replacement router will solve the problem otherwise I'll stick with the 64
bit encryption if necessary.

I have seen high gain antenna kits for wireless routers...it might help if
it is indeed a signal strength problem.
