okay, here is a puzzlement that i hope someone can help me with.

I have a wifi router that works. it communicates great with my desktop computer in another room.

I have an HP dv1432 us laptop, 6 years old, its wifi works fine with the neighbor's wifi signal and all hotel and airport wifi signals.

but i can't get this laptop to get wifi internet thru this, my own router.

it used to work fine. in Win XP it looks like it is connected, but while it sends a lot of packets very few are being received.

I tried shutting off zonealarm, no help. I tried changing the password and the channels, no help either. it's 4 feet away. transmitting b and g. yes, i enable the wifi button on the laptop.

i currently have an ethernet cable coming out of the wifi router into my laptop, works great. just no wireless connection.

any insight on troubleshooting this would be MOST appreciated!! i am tethered!

thanks, best, justin

fyi the internet wiring setup is a rcn wire into a d-link dcm-202 modem, that runs a wire to a vonage phone router, and that outputs to a netgear wgr614 v6 wifi router. hard wired works great. i see the router's wifi, it seems to hook up, then nothing.

Building on ’s description and the early suggestions from and , here are focused diagnostics and targeted fixes that avoid redoing the obvious steps already tried.

First, confirm whether the access point actually sees the laptop when it “connects.” Check the router’s admin page for a Wireless Clients / Attached Devices list—if the laptop appears there but traffic doesn’t flow, the problem is on the AP/router side (client isolation, MAC filtering, or encryption mismatch). If the laptop never appears, the association itself is failing and the NIC/driver or radio compatibility is the likely culprit.

From the laptop run these quick checks in an elevated command prompt:

ipconfig /all
ping -t <router_ip>      (observe packet loss to the gateway)
ping 8.8.8.8             (checks upstream reachability)
netsh winsock reset
netsh int ip reset

Interpretation: no reply from the router = association/relay problem; router replies but internet fails = gateway/DNS or routing issue.

Targeted tweaks that often help when a client works on other APs but not this one:

  • Inspect router wireless features: look for MAC filtering, “AP/Client Isolation,” and the current encryption mode (TKIP vs AES). Temporarily switching encryption mode (or briefly disabling security for a quick test) can expose compatibility problems. Re-enable security afterward.
  • On the XP laptop update the wireless driver and ensure Wireless adapter properties disable aggressive power saving, and try turning off WMM/802.11n options if present.
  • If diagnostics show association but heavy packet loss, check router firmware and apply official updates, and review the router’s wireless logs for repeated deauth/assoc failures.

If these focused tests still don’t reveal the cause, collect router logs and a short ping trace (to the gateway and to 8.8.8.8) — that data will pinpoint whether frames are being dropped at the radio, by the AP, or beyond it.

Common problem but some cases need different solutions.You said it work fine with other network but not your network. So the problem is either with your network or your laptop network settings.

1) Reset your router
2) Can your neighbour laptops connect to your network by wireless.
3) Turn off your firewall and disable any security softwares that may block the internt connection
4) Try and reconnect again. This time at various location around your house. Try putting it near your modem and next far away see whether it can pick up any signal. A faint signal or a slow one is already a good sign.

So your problem now is this laptop cannot connect to your modem but using an ethernet cable it can. Can other laptops you use at home, connect to the same network via wireless?

Can it even connect to the network. I mean if can your laptop connect to your network but cannot go online as there is no internet access. There is a big difference here. Can connect to network but cannot access internet is different from cannot connect to network. If your laptop can connect to the netwok but there is no internet access, go to your wireless preference there and check whether the ip address shown there match your house network ip address.

Please check your router settings, if it is enabled for wireless transmission.
