RE: unplug and power up dsl modem and router

Hello,
This is happening more to my wife's new Toshiba laptop running Vista than to
my Dell laptop running XP-SP2.
The computer will loose access to the internet, and the fix is to unplug the
power to the DSL modem and the wireless router, wait a few seconds, re-power
the modem and router, wait 3 minutes then start Internet Explorer. This has
always fixed the problem, but I would like to better understand the
underlying cause. This started happening more often after my wife got a new
Toshiba laptop. It often happens that my Dell laptop is still connected to
the internet. At first I thought that since only her computer was having a
problem that there must have been some problem with her computer and that
turning power off and on to the modem and router would not be the fix, but
it was the fix after all. I guess there is some part of networking here
that does not make sense to me, probably because I do not know a lot about
networking.

Is there some other way to attack the problem to make it happen less
frequently?

Also, I looked for a Vista help newsgroup, but could not find one.

TIA for any help,
Tom

Hi Tom,
Is the connection wired or wireless?, this can indicate a bad firmware or
defective hardware like the Router or the Modem, try to update the Firmware
for the Router and the Modem if possible then try the connection and see if
it will last and hold the connection.
Also This could be due to:
1- A Power management settings for the NIC, to know if the Power management
settings correct try this:
Right click " MY Computer" select Properties and then click on Hardware Tab
then click on Device Manager button.
On Device Manager locate this:
[+] Network Adapters, click on the Plus [+] to expand to [-] and locate the
Wireless NIC, then while highlighting the NIC click on the Properties Button.
On the NIC Properties window click on Power management and make sure this
check box is unchecked:
[ ] Let the computer Turn OFF this Device for power saving.

Click [Ok] and out, does it help retain the connection.

2- Best if She/ Both of you change from the Weak WEP encryption method to
the WPA-PSK more secure, also change from the default channel (11 and 6) as
your neighbour may using the same channel to access their wireless which can
interfere with Her connection, making Her losing access.

3- Update the Firmware for the Wireless from the Laptop Manufacturer.

Finally, Open a run command and type in:
ipconfig /flushdns click [OK]
ipconfig /renew click [OK]
netsh winsock reset click [OK]
Reboot your machine, does it help?.

Also try to reconfigured my router to use a HEX pass instead of an ASCII
string and then try the Connection, does it help?.
I recommend using WPA encryption method as it is safer than WEP, which
consider weak by Today's security average.
