Can a router cause dropped downloads?

Have an older DLink 802.11b wireless router. My PC is hooked is wired to the router (not using wireless). I have always had problems with dropped downloads. Anything larger than 20 megs would only complete downloading maybe 50% of the time. The other day, I hooked my PC up directly to the DSL modem. I have done a bunch of large downloads and they all completed... Am I right to assume that the router is likely causing my dropped download problem? Is there a certain brand I should look at as a replacement? I need a router because I always use the wireless access for my laptop.
 
it could also have been a bad cable. You removed the router and one ethernet cable, and the issue went away, so it was either an ethernet cable or the router.
 
Good troubleshooting practices have you make one change at a time to determine where the problem is. As nweaver said, either the cable or router were the problem but you do not know which at this point.
 
I would guess the router.
If it was a cable then even downloads below 20MB would have issues.

I have seen a few routers that overheat with long file transfer/lots of connections.
 
Router is the likely cause, in my 10 years of IT ive seen VERY few bad cables. If they are bad they are totally bad and dont work at all. The only way it would "sorta work" is if there was a mass amount of interference.
 
Any Router can cause such trouble if its MTU is set far off the optimal MTU for the type of connection

In addition Old Routers were not designed to be used at loads that people put on them in these days, they can drop connection similarly to the freeze that one would experience when trying to task a very old computer with very heavy grahic work.

I've seen many bad cables in my time. That is why the first step of Network troubleshooting is to check the physical layer. I'd guess that more then 75% of problems are physical. I had one just a few weeks ago that was a bad run in the datacenter's wiring plant. I had what looked like duplex mismatch issues, and talked to a tech who was in charge of their switch. After about 10 minutes (since neither of us had access to the physical) he ordered an end to end test, and they found an issue/fixed it. The "symptoms" were slow network access and dropped packets, Not even port issues in the show int.
