"clogging" a windows network with my MacBook?

I am hooked to my building's satellite broadband network via Ethernet to my 3Com OfficeConnect 11g router. I am running a MacBook Intel Core Duo @1.83 GHz with 2gb RAM and AirPort Extreme. I bought this computer last October but began having problems with connection speeds this past July. My landlord monitored the connections this evening and informs me that my MacBook is somehow clogging the network. He thinks I must have a virus of some sort (he is a Windows man). I tried explaining that Macs don't get viruses and that if I did have a Mac virus, it would be VERY newsworthy. When I check my upload/download speeds via Speedtest.net, I am currently accessing via only 182kb/s download and 199kb/s upload. The WLAN light on my router, however, is flashing almost at the speed of light.

If I disconnect my MacBook and have only my Cube connected via Airport 11b, he reports that everything looks cool, no clogging from my office. My questions: can I be infected with a Windows virus on my Mac machine that is screwing up all things network?? Is there something about my MacBook that can be causing these problems? Could it be a Windows software problem with the IPS?

Any ideas, remedies, suggestions are greatly appreciated, thank in advance.

This is only my opinion so take it for what it is worth. Try taking your "office router" out of the system if you can and connect only via the Airport Extreme. Second, I think you landlord is in outer space. How does your landlord know that your MacBook is "clogging the system". That must be a PC term. There is a potential for viruses on a Mac but until the Intel Processor came along it was extremely low and has increased since the Intel Chip came along and people are running Boot Camp or Parallels with Windows, but still a very slight possibility. I use Norton Antivirus and never have had a problem. I think that it's your internet connection and not your Mac, although it good to repair disk permissions occasionally and clear caches.

Good morning and thanks for your response. My son, a techno-geek-type, notes that there is a slim chance that there might be some malware running in the
background on my computer and I can determine this by going to a
utility called activity monitor and examining processes. His networking
knowledge is considerable and I will stop by his apartment this evening
and have him look at it. He also explains the speedy flashing lights about which my landlord was concerned are not an indication that bandwidth is being consumed but rather that packets are being sent and not receiving a response. My understanding is that if the network is slow, more packets will be sent in search
of responses; the faster the connections speed, the fewer non-
responses/flashing lights there will be. The Speedtest.net readings yesterday
evening were 182 and 199, certainly lower than expected averages. My
laptop runs at 1.83gHz on a 667mHz bus, my Cube (in the waiting room)
runs at a much slower speed: 500mHz processor with a 100mHz bus. That
might explain the 'acceptable' rate of flashing lights when only that
computer is connected to my network and might be a solution for my
MacBook if my Cube serves as share point for internet access.

I agree that this is much more of a Windows problem than my laptop but, as I'm sure you have experienced, convincing a Windows ISP/user that the problem and solution rests with them is VERY difficult. My landlord repeatedly iinsists that I have a virus on my computer……

Thanks.
