Cannot reach higher internet speed...

[larbac]

Hi

I'm having some problems (not very serious) but even though I have an internet connection of 1Gbps, I can't reach more than 300Mbps.

This is the result of this: sudo lshw -C network
*-network

Is there a way to speed it up?

Thanks

If your ISP is providing Gigabit speeds to you, and you have a Gigabit "modem"/bridge, and your router has Gigabit ports, and you have good ethernet cable from the router to the PC, then you should be getting (on the order of) Gigabit throughput on download. If not, the first thing is to shutdown your router and your modem, and leave them off for 10 - 15 seconds. Then start your modem and when it's completely rebooted (all the lights are on - sometimes a minute or two), then restart your router. When your router has completely rebooted, if you are still not getting Gigabit speeds, then contact your ISP and have them check their circuit to your location. They will say there are no guarantees, but they should be willing to make an effort.

I can get 1GB on another machines connected to the same router, even using the same cable. So this is really a problem with my Linux PC.

Your driver is tg3, Tigon3 from Broadcom. A modinfo check shows only one settable parameter: tg3_debug, which wouldn't be of much help.

You should consider switching to the bge driver, as offered and described on this page.
