I've just been upgraded to Plusnet fibre. Speeds are good - 72mb - but I have old devices I'd like to upgrade. So starting with my All-in-One desktop (non upgradeab) which runs just fine on Win7 but is only on wireless G. I get 26mb download which I guess is good but can I boost it with an AC adapter? I'll be upgrading my router to an AC one. I download a lot on this machine so maximum speed, short of plugging in via LAN is required. Homeplugs are a no because this is actually located on different circuitry AFAI as it's technically a different house (merged). I was looking at USB dongles like this: Linksys AE6000 Wireless Mini USB Adapter AC Dual Band by Linksys Linksys AE6000 Wireless Mini USB Adapter AC Dual Band: Amazon.co.uk: Computers & Accessories Thoughts and suggestions?
