I have installed Ubuntu on my Acer laptop, but I can''t access the internet. As far as I can tell it is because my wireless adapter (built-in Broadcom 802.11g) is not recognised. I have windows 7 also on the laptop and it does recognise the wireless, so I can only assume it is something o do with Ubuntu. I suppose it might need a driver. I have read that I could try to connect my laptop via a cable to the router, but sadly I do not have a cable, nor do I have any access to one or to any shop that might sell it, so I hope there is some other solution, maybe by downloading via the windows setup. If anyone can provide any guidance or advice I would appreciate it. I am completely new to Ubuntu, so please bear this in mind.
If this is driver problem you could try to install Broadcom 802.11g drivers by downloading them from Broadcom web site in your windows OS and then copy them to Ubuntu and try to install them there.
See if that will resolve your issue.
