My internet is very slow! It's not the service as I have 2 other computers who run very fast on wireless. I just replaced the ethernet cable which didn't do anything. My computer itself isn't that slow although it isn't fast either. It's a imac, 10.5.7, 1.8 GHz PowerPC G5, memory 2GB DDR SDRAM. I thought about switching it to wireless,I'm not sure as I don't see it on the top toolbar and I'm not sure how to set it up if my machine actually has it. Could my router be bad if my other computers are good? any suggestions would be great.
