Problems connecting to the net

This hasnt really been a problem in the past but right now its becoming an annoyance and its making me very irritated.

For some reason, my Sony VAIO FZ290 cant connect to the internet on boot up. It either says Unidentified Network (networks name) or it says

connection: Local Only

instead of

connection: Local and internet

I dont know why this is happening because my laptop is connected by Ethernet cable directly to my router. However, on the 2nd boot and after restart my router like 5 times, it finally decides to connect.

The thing is i dont know if this is a router related problem or if its my laptop's crap connectivity capacities.

Also, i realised that I get a message saying

Windows has found that there was an IP conflict (something about more than 2 computers having the same IP on my network).


Well im all very confused since this only started happening recently.

Can someone help me on this issue? Thanks!

 

log into your router and set it to act as dhcp server
make sure your notebook and any other computers that are connected to your router are set to receive dynamic ip

 

could you explain it a bit more? im bad with wireless networking.

dhcp is enabled

 

Okay first of all, why are you getting IP conflicts...Do u have more than one computer connecting to this router? If not it seems that you don't have any Security set up on the router and someone else is on your network. You need to log into your router and config. it properly w/ security and check the other configurations. What router is this? brand/model

Edit: Log into the router by entering it's IP Address in your web browser. Find the router's IP by going to Start--> Run--> type cmd and hit enter. Then type ipconfig and hit enter. The default gateway is the IP Address of the router.

And out of curiousity, what antivirus program are u using?

 

Yes there is one other laptop connected to my computer, i know how to connect to my router but i dont know how to make my router act as a dhcp server like the other person said.

I do have security of my router (WEP)

i just want to solve this issue.. its really annoying and making me have a bad day

Like, i havent even been able to start my research report yet cuz of this thing

 

So you have Ad-hoc set up?

Check your IP settings....it seems you don't have a DNS IP Address configured on the Network Adapter and it seems the other computer has the same IP Address as the other. Do an ipconfig /all on each computer and post the results.

 

I think so


btw, my router is a Linksys WRT300N

 

You need to get rid of the ip conflict. Check the ip address of each computer to see if they are actually the same (start->type cmd in the search box, type ipconfig to check ip address).

Most router dhcps are on by default. Most likely one or even both computers are set to a static ip address. You need to change it to "Obtain an IP address automatically" in the tcp/ip properties for the network adapter. (can be difficult without detailed instructions...)

 

But if he has an Ad-Hoc network set up as I suspect (from his first sentence in post# 5), I don't think setting them to "Obtain automatically" will be ideal.

 

You need to change your security to WPA(2) AES Personal, wep is not secure at all. Beside Vista does not play well with wep, it prefers WPA2. Also make sure your router is broadcasting the SSID.

 

I don't think most people would know whether the network connection is ad-hoc or not and the chances of running a wired ad-hoc network when you have a router to connect to the internet, I would say, is probably low.

DHCP is on so it doesn't seem to be ad-hoc... reading the post again, it does seem someone else is on his network, since it used to work without problems, unless somebody changed the configuration on one of the laptops...

If no one set up any static IPs intentionally, I second that on switching your WEP security to WPA2.

We would need your IP information on both laptops to confirm things, though.

One more thing... make sure all laptops/computers are connected to the router LAN ports directly and not to another computer as you mentioned in one of your posts... it sounds confusing... or perhaps it's not connected properly?
