Linux Mint 11 (64-bit) - Dropped Packets

[cKGunslinger]

So, I recently build a new desktop and replaced by old Linux box with it. (I'm using the same IP and everything.) This one is running Linux Mint 11 (64-bit), while the old one was 32-bit Mint 10.

Anyway, I noticed the internet seems a bit slow, but since I have crap internet, I didn't pay much attention. Also my router web page took ~30 seconds to load.

Then, when I tried to mount my network drives from my server, it was quite noticeable. The machine would lock up for minutes, eventually mounting. Then browsing the mounts took minutes to show each directory.

So I ran ifconfig and got this:

eth0      Link encap:Ethernet  HWaddr c8:60:00:68:50:51  
          inet addr:192.168.1.102  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::ca60:ff:fe68:5051/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:9216 errors:0 dropped:[B][COLOR="Magenta"]9216[/COLOR][/B] overruns:0 frame:9216
          TX packets:9530 errors:0 dropped:107 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:7372285 (7.3 MB)  TX bytes:1587421 (1.5 MB)
          Interrupt:48

That seems bad, no? I'm not sure what to try next. For me, Linux networking either works or doesn't - I'm not used to diagnosing "kinda works, but really poorly."

I plan to use Live disks for previous version and 32-bit versions, as it may be a network card driver issue. But if I lose 64-bit, I've got a lot of wasted RAM..

Well crap, now I feel stupid for posting:

I can search fruitlessly for 2 days, then find the answer 5 minutes after posting to a forum. I should probably just start with that first, like everyone else on the internet. ;-)
