I've found an Acer Aspire V5 laptop that I'm interested in buying. Its spec. seems to cover everything I need, with one exception - the wi-fi spec is listed as 802.11b/g. I want 802.11n.
I have fitted a new hard drive and memory to a laptop in the past, but I have no idea whether it is equally simple to fit an improved wi-fi adaptor. Is this straightfoward? Any idea what the adaptor would cost me?
Changing a wireless adaptor is simple (except some only have one antenna socket). An option is to use a dongle. I've bought a number of Edimax from Amazon recently - 8 quid and very good connections. Can't add a link at the moment, as the website won't let me!
A couple of further questions, if I may, about using a dongle:
(1) I notice that the Edimax dongle has no visible antenna, so I assume the antenna is internal. So it must be very small. Does this limit the range of wi-fi reception?
(2) Obviously a dongle will occupy a USB port. In order to get maximum speed of wi-fe reception, does this have to be a USB3 port? And if it can't have its own dedicated port, would its use in a hub reduce wi-fi speed?
