Connection issues,, best approach

Im meant to be participating in the Spec cup this evening. However whilst having a bit of a practice last night I was having connection issues.

Ive restarted all my hardware and they havent gone away. Im currently getting 7MB down - not great but bearable.. But im getting around 0.1mb up - which clearly is going to cause problems.

Bieng as how this is going to be my first race event here I surely dont want to mess it up for everyone else with mega lag... whats the best approach here ?

Be sure your XB is the only equipment accessing the Internet.  Also, it is best if you are using a wired connection at those rates. This may not solve your issues, but will--hopefully--improve them.

Already using wired - theres almost certainly a fault which I have raised with my ISP.

I meant more in terms of not being able to participate in the race (I mean I can try but I was playing online last night and experiencing major lag - bouncing all over the track apparently)

You wasnt lagging bad last night
