SLOW - I don't know exactly what the problem is, as the router and internet is the landlord's, who refuses to do anything about its super sluggish connectivity that started a few weeks ago when a new resident moved in and his Mac started showing up on "SHARED" in my Finder, with a constant message of "Another device is using this computer's IP address" whenever I wake my Mac from sleep (oh I get the message even when nothing is in "SHARED," though) So can I just buy one of those Wifi extender devices - the little box like things at Walmart and set up my own network (within the landlord's Wifi(?- that's how it works, right?) and then would I be able to use Wifi faster? Or is there another electronics I need to buy to connect faster? The landlord doesn't give a s^!t so no calling the provider even though multiple residents have already complained and he even suspects that the new resident brought the problem (hacking the network or something..) The router's acting up more and more each day - now I have to restart it a few times every hour to bring it up to barely acceptable speed. One weird thing is that after restarting the router and if my Mac doesn't give the "Another device is using this computer's IP address" message, then internet is still slow so I have to restart the router again and again till I get the message... Any ideas on what's going on? And what can I buy?
