I am having difficulty connecting my laptop to our router. I have three other laptops and my PC connected find, but it is just my other laptop that is giving me problems. At first it would say I am connected, but I would not be able to go on the internet. I would re boot than it would tell me I have "limited or no connectivity". This is the only laptop that I am having problems with. The other ones are working fine.

Help!!

Building on points raised by , and , the situation where one Toshiba reports “connected” (or “limited”) while other devices work is usually a local configuration or driver issue on that laptop — not the ISP or router hardware. Common culprits are a DHCP failure (APIPA 169.254.x.x), DNS or proxy settings, a wireless-driver/power‑management problem, a security (WPA/WEP) mismatch, MAC filtering or a DHCP-lease conflict on the Linksys, or a local firewall/security suite blocking traffic.

Useful, quick diagnostics (commands vary by OS; Windows examples shown) — run these to see what the laptop actually has and whether the gateway/DNS respond:

Windows CMD:
ipconfig /all
ipconfig /release
ipconfig /renew
ping 192.168.1.1
ping 8.8.8.8
nslookup www.google.com

Expected results: an IPv4 in the router subnet (e.g. 192.168.1.x), a valid Default Gateway (router IP) and DHCP Enabled = Yes. A 169.254.x.x address indicates no DHCP lease. Successful ping to the router but not to 8.8.8.8 points to upstream/DNS; failure to ping the router points to local wireless/adapter issues.

Router-side checks for Linksys models: confirm DHCP server is enabled and the lease table doesn’t show duplicates, verify MAC filtering is off (or the laptop’s MAC is allowed), and confirm the wireless security mode — prefer WPA2‑AES; very old adapters can fail on mixed or N-only modes. A direct Ethernet test to the router isolates wireless from general connectivity. Also try a temporary static IP inside the router subnet to test packet flow.

Other practical fixes: update the Toshiba wireless driver, disable adapter power‑saving in Device Manager, clear saved wireless profiles and re-create the SSID entry, check browser/OS proxy settings, and temporarily disable third‑party firewall/security suites. If hardware is suspected, booting a Linux live USB or Safe Mode with Networking can confirm whether the problem is OS/software or the Wi‑Fi adapter itself.

well i think this might be a problem on the laptop other computers on your network are working fine have tried adding the network manually to your laptop and by the way what is the operating system of the specific laptop that is having trouble connecting.

First there is more info needed to help, but you need to make sure that the router is setup correctly. Is it a N router or a B&G? you need to make sure that the laptop supports the router configuration. The router can be setup for Mix B,G,& N or Mix B&G.
What wireless signal is your computer configure to receive?

I was able to get connectivity on the laptop. It now tells me I am connected and the strength is excellent, but I am unable to go on the internet.

check if the laptop is getting a valid ip address from the router? What is the wireless security encryption set on the router?

Member Avatar for sydette

How do I find the ip address on the laptop? How do I know if it is a valid address? Where can I go to find the wireless security encryption on the router?

Member Avatar for willjackson

before we could determine the ip address what is the operating system of your laptop the one that you have trouble connecting?

Firstly, I wanna know if you set up your laptop the same way like the others? And what's your internet connection?
