Trouble Staying Connected To Network...Speed Number Fluctuates
I just got a Inspiron N5110 and I noticed that only with this new computer the speed for the router fluctuates. It only happens with this new computer. I have Windows 7. The router speed fluctuates from 54 to 48 to 24 to 54 Mbps. The router is usually always at 54 Mbps. The router is about 7 years old.
When I unplug the router and plug it back in, it works fine for a bit. There is nothing wrong with the cable modem. It works fine. I use this computer for work so I have to have this running perfectly. I must be missing a setting or something.
The router we have is a D-Link DI-524. I also sometimes get a yellow triangle with a black exclamation point when the network is lost.
I don't know how to fix this. Any help would be appreciated.
