I have a new DIR-615 router and two computers: a desktop, and a laptop. The desktop is connected with an ethernet cable. The laptop has a wireless G card.

When I download a large file from the Internet to my Desktop, the transfer speed is 1.1 MB/s.

When I download a large file from the Internet to my Laptop, the transfer speed is 370 KB/s.
 
When I transfer a file directly from my Desktop to my Laptop, the transfer speed is 2.2 MB/s. (Running WAMP on the Desktop, Firefox Browser on the laptop.)

I have disabled all AV/Firewall software for these tests. I also use this laptop on my University campus where I can download at 1.5 MB/s, so I know there is nothing in the Laptop limiting my transfer speed.

Any ideas why my Wireless Internet downloads are so slow?

Note 1: All transfer speeds posted above are in megabytes, not megabits.

Note 2: I have disabled Wan Traffic Shaping under the QOS Settings. This did not have any effect.

You might consider changing the laptop G card with a better one or a N card. The N protocol makes a big difference.

Thank you for the reply. But given the unusual nature of the problem, I'm having problems justifying the expense. Shouldn't I be able to get the same bandwidth out of Wireless G regardless of where the packets originate?

I still have not resolved this problem. However, I have discovered that the problem goes away when I open multiple TCP connections. By downloading several files at the same time, I can get up to 1.1 MB/s (the speed of my internet connection).

Does this give anyone any ideas?

Go ADVANCED > QoS Engine and uncheck both boxes, save settings and see if that makes a change.
