Many devices chat all the time. All it takes is one to be infected and it's game over.
In other words, I see nothing wrong here. It should be slow.
I have a Linksys E3000 router connected to a Huawei modem. I'm currently paying for 6mbps download and 2mbps upload. There are about 35 wireless devices connected to the network.
The internet speed was very good (even with 35 wireless devices) until i set up two access points, one Engenius (indoor unit) and one NanoStation (outdoor unit). After setting up these APs the speed has been crawling. It's so slow. I don't understand why. Please how do i improve my network speed?
