I'm using the same PC to use SLED10 and Windows XP. On SLED, the internet is ridiculously slow. On Windows, it's fine.
There is one difference between the way I connect to the internet with Linux: I plug it straight into the wireless modem/router. This is because Linux won't recognise my wireless network card (I've posted a question about that
here). On Windows, I don't use the wire, I connect wirelessly.
I'm pretty sure, however, that the router would not serve up a dramatically slower broadband speed just because the computer is wired in rather than wirelessly connected. It seems a bit odd.
Any ideas?
BTW, the broadband modem/router I am using is a Dynamode R-ADSL-C4W-EG.
And, as I mentioned, I'm using SLED10.
Please note I am a complete beginner with Linux.
