You said: "I'm a little computer geek so I know what I'm doing" and that is NOT true! You obviously have NOT taken "networking 101".

Do what they said, use wire instead of wireless. You already showed that wire resolves the problem, so you proved it MUST be your wireless link that is the problem! You have obviously NOT thought this through. What they did NOT tell you is they know exactly what the problem IS, the wireless link itself. YOU are suffering from the dreaded "party line effect" which they will NOT admit exists. The party line effect is a general slowdown of network THROUGHPUT. SPEED is constant since speed is determined by what radio frequencies you use. Throughput is the quantity of data moved over time. It is not how fast your truck travels at any given point in time (speed), but how much of a load (throughput) it can carry back and forth per day that counts. What happens is you send and receive data in high speed bursts. With wireless, the more users share the line so to speak, the slower ALL go as a result. There are two reasons WHY his happens. First, the access point has only ONE transmitter so it can "talk" to only ONE user at a time. More users means each user gets less individual time because of sharing the transmitter talk time, which means shorter and shorter bursts of data per user. Second, traffic jams. On a party line, you listen and then if the line is clear, you talk. No problem. If the line is busy, you wait for the line to clear and then talk. Again, no problem. The problem surfaces when someone else is waiting just as you are. Both of you try to talk when the line clears, which makes for interference, and neither of you get through. So, you wait for a reply and not getting one in a reasonable time, you try again. And so does the other guy and you collide again and neither gets through. This colliding goes on for a while until eventually, you get out of sync enough that one of you hears the other when you listen to see if the line is clear, and that puts you into more waiting. There is no one directing traffic, no traffic cop on wireless. THAT is what a traffic jam IS, dead time with no data moving because of transmission collisions. Both of these things slows you down. More users means slower traffic, less throughput for everyone who wants to use the line. Of course, your provider will NOT admit that this happens, but they DO know about it, which is why they told you to swap to wire to see if the router itself, the hardware, is the source of the problem. Which you proved is NOT at fault for the slowdown. How many users on YOUR network? How many other wireless networks are in your network list? Each of those networks COUNTS against you as users even though NOT connected to your access point. The thing is, they have transmitters just as you do and you are all on the same party line (set of radio frequencies) which means you have to wait while THEY talk just as THEY have to wait while YOU talk, which is why everyone slows down equally when there are more then one user. One user means no competition for air time. Two users mean you each get HALF the access time available. Do you see what the problem is now? Hmmm? By the way, "hey" is for horses... Before you claim to be an expert, or a "little computer geek" as YOU claimed, you should at least do your homework BEFORE you open your mouth. "Little" is right... as in LITTLE knowledge.
