Is anyone having this problem? I have a Toshiba Laptop and Vista is the O/S. I use it for home. I have a Realtek wireless network adapter. Linksys is the router. I am having trouble connecting to the internet. It was working fine for 5 months and then a couple of weeks ago no internet connection at all. On the wireless network adapter properties, IPv4 is local and the IPv6 is limited. I tried pinging the IP address and the computer said invalid IP address. Question is where does the IP address go? On the IPv4 or IPv6 configuration for the wireless network adapter? What should my LAN configurations be? It also has IPv4 and IPv6 configurations but I have it set to autoconfig. I also tried disabling the wireless network and enabling it again. I tried ipconfig/release and ipconfig/renew and that doesn't seem to do anything. I also disabled the microsoft windows firewall. I am at my wits end.

Please help me.

Thank you :(

A concise troubleshooting addendum for the “Local access only” Vista Wi‑Fi problem (Toshiba + Realtek adapter, Linksys router). Replies from , and point toward adapter/configuration, router and security‑software causes; the checklist below prioritizes quick, non‑destructive tests and a few safe fixes that are complementary to the existing suggestions.

Confirm whether other devices on the same Wi‑Fi have working Internet. If other devices work, the fault is local to the Vista laptop; if none do, focus on the modem/router/ISP (check the router’s WAN/Internet LED and the router admin page for a valid WAN IP). On the Vista machine inspect Network and Sharing Center → Manage Network Connections → (right‑click) Status → Details and note the IPv4 address, Default Gateway and DNS. An IPv4 in the 169.254.x.x range or a missing Default Gateway indicates DHCP failure. As a controlled test, assign a temporary static IPv4 inside the router subnet (example: 192.168.1.50, mask 255.255.255.0, gateway 192.168.1.1, DNS 8.8.8.8) — Internet returning with a static address points at a DHCP/router or filter‑driver problem.

Further laptop checks that often fix this class of issue: update or reinstall the Realtek wireless driver (prefer the vendor or Toshiba package), disable adapter power‑saving in Device Manager, verify the Windows DHCP Client service is running, and uninstall any VPN/virtual adapters or leftover network filter drivers from expired security suites. Reset the Windows network stack and reboot with:

netsh winsock reset
netsh int ip reset

On the Linksys/router side confirm the DHCP server is enabled, check the connected clients list and any MAC/access controls, and verify the WAN shows a real ISP‑assigned IP (not blank or 0.0.0.0). If kernel‑level AV/network filters are present, remove them for testing. If the problem persists, collect Vista’s connection Details output, the wireless driver version, and the router make/model and firmware — those items greatly speed targeted diagnosis.

This happened to me. Working OK then “Access: Local only”
This solved it for me. The network properties needed resetting. Make sure Network Discovery is turned on in Network & Sharing Centre. Under Tasks on Network & Sharing Centre select “Manage Network Connections” then right mouse click the network you want to connect with and select Properties. Ensure Client for Microsoft Network is included in “This Connection Uses the Following Items”, if not add using Install. Then select TCP/IPv6 & click properties and set Obtain IPv6 & DNS addresses automatically. Do the same for TCP/Ipv4. Hope this works for you.

In tech support we see this and root cause for several has been expired Norton 360 - if yours is expired uninstall it completely.

Lots of other possible fixes if you goggle the issue..other possible fixes are:

The need to remove the wireless connection and recreate it manually

Disabling IPv6

Disabling the UAC control in Security Center of control panel

Check Internet Options, Connection, LAN Settings and make sure Automatically Detect Settings is checked, it seems it is not checked by default in Vista.

Changing router channel from 6 to another one (ie 11 or 13)

Good Luck...and upgrade to Win 7 if you can...
