Surfing slows down printing...

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance



Hi all...

last month I installed a new 3COM Officeconnect 3CRWE554G72T wireless
router.
4 PC's are fixed line (Win2k), 2 are wireless (XP and Win98). One of
the Win2k machines has domain master and maintains serverlist (registry
flags set to True and On, and off on all other machines).
I am using the Netbeui protocol for filesharing and TCPIP for internet.

I noticed a new phenomenon, whenever surfing the internet (average
weight sites like Yahoomail) and printing simultaneously,
the printer slows down and hangs every few lines of printing, then
continues.
The printer is HP Officejet G85, connected to one of the computers via
USB and shared over the network.

The 3COM Router is configured with DHCP. the 4 fixed machines are
configured with static IP's. the wireless machines are configured
dynamically.

Before we had the router, there was a 3COM network switch and the
internet was only on one PC (connected directly to the cable modem).
Our ISP is cable, with win2k dial up VPN and L2TP protocol.

I have tried spyware/virus scanning. I have also added Hosts files with
the IP's of all computers on the network, on each computer, and removed
"my network places" shortcuts to shared drives, replacing them with
direct mapped drive letters.

I have also noticed that one of our slowest computers, an old win98
Pentium II machine (with a PCI Wireless G card), grinds down to a
crawl whenever some large file is downloaded on another computer on the
network.

I'm assuming that the network now handles more traffic due to the added
TCP/IP internet packets (which before were not part of the network) but
shouldn't a 100MBPS connection (all our NICs are 10/100 speed) be
sufficient for normal business printing and internet browsing at the
same time?

Would removing the NETBEUI and reverting to only TCP/IP use for both
filesharing and internet be helpful?

Thank you for your help.
