Hi, I hope someone can help. I have two laptops connected by ethernet cable to my adsl wireless router and I am getting massively different download speeds. Computer 1 (main use) Computer 2 The first computer gives different speeds from [this.site.has.been.banned.for.spamming} of between 2-3Mbps while computer 2 gets around 5Mbps consistently from the same site. Presumably the issue is with the setting on computer 1 but I'm not sure what to change and how. Thanks for any help.
