internet disconnects @ Google maps?

I use Vista and have 2 computers online sharing a wireless router, via cable
modem (Comcast).

It works fine except when I go to google maps, after a minute or two, I lose
the connection and must reboot to get the connection back. (it no longer
sees that connection -or any other, i.e. neighbors signals even after
closing google maps).

Suggestions of what's going on and how to remedy?

don't know,but have almost the same problem. Also with google earth or
acessing google maps I lose my internet connection. When I close
google maps ore earth after a few moments my connection is back ????
For the rest my system is working fine...I keep searching and let's
keep each other update

Yeah, I get that exact same problem. extremely, Extremely frustrating.

I have the same problem with a Linksys Wireless Gateway to a GTC Cable
connection. I agree very frustrating!!

same thing here with Belkin router.
I've tried bypassing the router and it worked just fine.
I called Router Tech support they said you need to get PORT number and
Protocol used by Google Maps.
I don't know how to get those info though!!

 

Use a copy of Wireshark. Wireshark allows the packets on a PC Ethernet
port, to be recorded in real time. (Wireshark was formerly known as
Ethereal packet sniffer.)

The outgoing ports being used during a Google Earth session, are
80 and 443. 443 is used for HTTPS (secure HTTP). 80 is the normal
port for HTTP traffic.

My trace had hundreds of packets in it, so I'm not going to
characterize the incoming port numbers.

If the Belkin router has a log screen in the web interface, see if
some security feature has been tripped. My router has "SYN FLOOD"
protection, and if I aim a "stealth check" web site at the router,
it doesn't give an honest assessment, because the router throws
away the majority of the packets. Maybe something similar is
happening with Google Earth, but I cannot imagine what that would
be. The application developers at Google are well aware of firewalls
and port numbers, and would not be using something non-standard
just for the hell of it. Outgoing ports 80 and 443, might be used
for a session with your favorite Internet retailer or your bank.

Opening port 80 solved the Google Maps disconnect problem for me. Is
it safe to leave port 80 open all the time or should I only open it
when I use Google Maps?

Outgoing 80 is used by browsers, to reach web servers.

Incoming 80, would be opened if you wanted to run a web
server in your home. That would be less secure, in the
sense that hackers could "tip over" your home web server.

If you're not going to use outgoing 80, the computer
won't be quite as useful to you, because then you
couldn't web surf with IE or Firefox or whatever.

I would guess Google used the ports they selected,
as they'd be used for other things anyway. So you
shouldn't really need to do anything, to get
Google Earth to work.

Some well known port numbers are listed here.

On my networking setup, outgoing 80 is not filtered
in any way (so my web browser works), and all incoming
well known ports are closed (as I'm not running any
home servers to the Internet). Ident (113) is port
forwarded to a non-existent private LAN address. If
you port scan me, I like to pretend I have a "stealth"
status from the outside. It is hard to check that it
actually works, because my router has "SYN flood"
protection, and the scanner website I used, causes
the SYN flood protection to get tripped, negating
the test results. So I think I'm stealthy, but I
cannot be sure. When I'm port scanned at a high
rate, the router throws away the packets and the
computer never sees them.
