I need to figure out the reason(s) behind, and what to do about, my poor internet connection. It's very inconsistent. It can be pretty adequate at times, and at other times it's really laggy. I am in a 3-story house in Boston. The modem/router (both in 1 device) is in the common room on the second floor. I'm relying on the wireless, since winding a cable down the stairs and across the hallway would be very unwieldy. ********************** So, first problem: I don't understand this situation. If the problem is simply poor wireless signal strength, then why is my internet connectivity not consistently bad? It's only bad sometimes. Or much of the time. But the point is, it's not always good, it's not always mediocre, it's not always bad. It varies between bad and mediocre and sometimes *really* bad. Why would it vary? Is it possible for a router to output poor signal sometimes, mediocre signal sometimes and good signal sometimes? Doesn't it always transmit the same quality signal?? Secondly, still with first problem, why does Windows tell me that the signal strength is fine? The quality of my experience appears to be completely (or maybe just mostly) decoupled/not correlated with how many bars I see in the task tray. It seems that sometimes I see 4 bars and yet websites grind to a halt. Other times I see 2 bars yet browsing is fine. Wtf? I think my roommates on the second floor do not experience any issues. I haven't asked the other one yet. *** Now, second problem: what do I do about this? Just get a second router with powerful antennas and set up some kind of repeater thing? I feel like I should find out more about what's going on before I start spending money and -- more importantly -- time that I should be spending on grad school instead of dealing with this crap. Thanks for any help.
