Ok, recently my computer and internet was working just fine until last night. MY computer just didnt connect. So i called dell and they just fixed it right now by going into my router settings and changing a few things like changing my security to WPA Personal from WAP Open. Before I was usually getting full bars with excellent and good signal strength, but now after I fixed my internet problem, my signal strength is at poor. I tried restarting the computer but it did not work. What should I do? How can I fix it? Also, I have 2 antennas from my wireless computer and they are both parallel from the floor.
