It seems to only be an issue when I am at home. My router is a netgear that is 4 + years old. Could it be effecting how my computer works? It doesn't seem to be as big an issue when I am on other wireless hubs, just my one at home.
In that case it's either the router or your ISP. Try a wired connection directly to your broadband modem. If that's still slow then it's your ISP.
So depending on the conclusion, either buy a new router or try setting your Mac's DNS manually to the
http://www.OpenDNS.org servers (this doesn't improve speed for me, but plenty of other people say it helps them).
I have a 3 year old Netgear wireless router (WGR614v4) and it's worked flawlessly till recently. Now, it can take up to a minute to get a connection to it when waking from sleep (from a couple of Macs
and a PC laptop so it's not a Mac issue) and I've had to power cycle it a couple of times in the past couple of weeks. I'm hoping to limp along with it till the revision of the Airport Extreme that has a built-in Gigabit 4 port switch and multiple USB sockets (... wishful thinking ... but that has to come considering there are now competing WirelessN routers with gb ethernet that are 2/3 the price)
