internet connection problem

[nomamasboy]

I'm sure there is a simple fix for this, but at the moment it's
elusive. I have a cable modem worked fine until we had an apparent
power surge due to a storm and I rebooted. Everything came back online
except the internet. So I did the usual unplug the ethernet cable, the
power cord, the coax all to no avail. I can ping my ip address and the
default gateway just fine, but when I try to ping the dhcp server it
times out. When I look at network connections it says that I am
connected to the net. I've renewed the ip address- still no launch.

Any ideas guys?

Thanks,
Tim

did you check with your ISP to see if their DHCP server is down ?

I tried to get through to their tech support hotline, but the phone
tree was endless. As soon as I get home I'm going to try again. If it's
a problem on their end (which my gut tells me it probably is) that's
fine, but I know just enough about computers to get myself into trouble
so I thought I'd ask some wiser folks.

Thanks Haggis

Tim,

When the cable modem plugs/cable are attached, then you disconnect the
coaxial cable does the cable feed light disaapear? If so, you are getting a
connection to your modem but there might be a voltage issue with the outside
feed leading to the pole.

You can test the DNS by going to:
* Start > Settings > Network Connections, click your connection
* Click 'Properties' > clcik on 'Internet Protocols (TCP/IP) then clcik
'Properties'
* Select 'Use the following DNS Server addresses'
* type 4.2.2.2 for the 'Preferred DNS Server'
* type 4.2.2.3 for the 'Alternate DNS Server'
* Click OK & restart computer

Note:
To return to your old settings later, instead of selecting 'Use the
following DNS Server addresses',
select 'Obtain DNS serveraddress automatically, click OK & restart computer

Thanks Drew- You mentioned an outside pole and I remember that there is
a node a few blocks away that about a year ago had a loose connection
somewhere and the bandwidth dropped considerably for a few days and
then jumped back up to +6 Mbps so I never gave it another thought. If
that node were damaged in some way during the storm that might be the
problem. I will definitely test the DNS as you recommended tonight and
take note of the cable feed light when disconnected.

I certainly appreciate the help.
