If its about recovery u may not have installed all the required drivers from the dvd. Just make sure u have installed the required drivers for the wireless internet connection. With Dell laptops u need to install the drivers manually from the dvd.

prolly the culprit is wireless, try pluggin in a cable and see if that works, if it does, update ur wireless driver..

I am sure you had checked the Network connection and it would say "connected" if not there is a problem. And also the  internet option on control panel, LAN setting must be checked  automatic. Sometime if you discontinue the Ethernet driver and restart , if will update the Ethernet driver and may connect to internet. Sometime, I clicked to auto-update to run the internet, it may connect to Internet. Good luck.

My brother had a same problem. Device manager showed that all drivers are installed and there was no yellow flag but yet the internet wasn't working. But he downloaded new driver from dell's website for his laptop model and installed that one then the internet started working. Give this a try, this may help you too.

I'm also using Inspiron 1420. As bange bro suggested, try to use internet by pluggin in the cable. Also, I guess if you upgrade your driver for the wireless device from Dell's site, your problem will be fixed. Note that all the drivers will not installed when you install Vista from the CD/DVD provided by Dell.

download drivers from dell website for the model of your laptop. It is driver issue.

first to check if the computer is connect to the router or not. if you are using ethernet wire then you will have to reset the router by pushing the reset button on your router.wait for 15 to 30 mins.also reset your dsl modem which you have to do first before resetting router.this is under all drivers installed condition.while the modem and router is resetting shut down your laptop and start after like 30 mins.enjoy!

some of you guys are giving him ridiculous suggestions.  if you reset the router you will lose all settings, you cannot restore as its a newly formatted computer.  Like someone suggested use hard wire to get connected then update driver for the wireless nic besides that if your physical nic is not talking you gotta find another computer get the latest driver from dell and update it.  No need to reformat again as you will come across the same issue.  Also you can try to update your OS....some issue might be resolved....

Resetting the router will reset the ipaddress in  computer if the ip address is assigned by  DHCP. as mentioned " couldn't connect to the router" the situation could be not getting ip address from router.by resetting the router resets the ip address for the laptop nic card too which will solve the ip problem.

Tech ur worng, resetting ip on router will not reset ip on the computer/nic.  IP has to be refreshed on the computer or until the lease expires or hard reboot required.
