I have a Dell inspiron 1525 and was wondering if I needed an ethernet cable to connect to the internet during installation of Ubuntu? Or is an ethernet cable required to connect for the first time after installation?

This question is fairly vague, but in brief, the answer is "no" - the Ubuntu installer will allow you to pick a WIFI network for installation. Even then, a connection to the internet is only recommended, not required, to complete Ubuntu installation.

Your family model, the Dell Inspiron 1525 all come with a wireless network card. They either have a:

  • Broadcom 4312 Based Card
  • Dell Wireless 1397 802.11g Half Mini-Card (Based on Broadcom 4312)
  • Dell Wireless 1490 802.11a/g/n Full Mini-Card (Based on Broadcom 4311)
  • Intel Next-Gen 4965AGN 802.11a/g/n Wi-Fi Card

If you happen to have a Dell with the Intel 4965 chip then the wireless card should work out of the box. If you happen to have any of the others then I suggest you read this answer which covers all models here and more.

So there is no need to use a ethernet wired connection except in the case that the wireless card needs proprietary drivers (Not detected or installed during installation), in which case, you need a wired cable connection to download all updates and drivers for your wireless card (And anything missing for it) before disconnecting the cable and using the wireless card.
