wow, my guess this is a 1 PC home, ?
no router stated, or if its yours or ISP (junk) I run my own gear.
try my steps for best fast correction of the problem.
is the router with WIFI, what is name of router and model number.
and get 10 times better answers.
- try another cable yet,or other router RJ45 Ethernet port?
- try 2nd PC here< or a friends,? work now? no then router issues....routers are complex, and no router stated so....
- if router is wifi try a pc yours or others or cell in wifi to connect does that work,???? you need to set up the router to use wifi.
- Ok there are 2 diagnostic paths here. 1 is router and your one and only PC and no friends have a PC, right? lets to that next.
Friends pc dead. on cable. (new cable not yours)
that means the router is broked.
even the lease time wrong can cause that.
did you reset the router to see if the connection comes up
that be first first.
if the router is still dead. you need access rights to check it.
so this help now ends.... lacking whats there or how owns it.
way 2 , 1 PC dead now, on 2 either net cables and all router ports dead. but other PC work on your router, simple no?
if just your pc is dead, it can only be 2 things
a: bad hardware (blown NIC chip) network interface chip.
b: bad software, or INSTALLED WRONG !!!
C; NIC parameters wrong called the STACK.
lets work B: (a; is hopeless, needs NIC new)
B:
first off what PC is it and what does HP support.
the deal with HP mobo, is that the underlaying chips must
also be right for the NIC chip to work
many HP have up to 5 nic chips used there new.
(options) that right, up to 5, and the HP page covers that
if you had read it
first ill carbon date this beast 2007 it is , on the cusp of zero HP support,(10yr rule) get the software while you still can.
DV2500T
HP says
HP Pavilion dv2500t CTO Notebook PC
HP told me only Vista support.ed!!
well ,why leave VISTA. ? vista runs NIC ok for sure,!@
now you must find all errors it the system for drivers.
that can mess up the NIC.
since now on W7 you are committed it seems.. ouch
and you used a real windows disk to do that, not HP disk.
so there will be missing drivers doing that. or wrong.
the NIC here is
Marvell Yukon 88E8039 PCI-E Fast Ethernet Controller Driver
here are the only drivers that can work
off marvell site
if you use CP control panel
DM
and RC right click the NIC, you will see what chip is there
but be warned, other chips may need w7 drivers (correct)
to allow the NIC to run right, that is why never upgraded
with out HP , support,
but i have vast times but GO THE DISTANCE on all drivers
called HARD long work.
as seem below.:
http://www.marvell.com/support/downloads/driverSearchResults.do#
if the network stack is all good
and your pc runs on your neighbors router with same cable
then the parameters in the router are wrong.
at he elevated command prompt type, (winkey+x) (admin)
IPconfig , enter
see that IPV4 , that is your router assigned IP, using its DHCP server. mine is set up with 10's on purpose.
the gate way must be correct and not blank
