If you have slow and/or high-latency (laggy) internet access, and you get stuck downloading resources when joining BYOND games, try decreasing your MTU.
Disclaimer: I am not responsible for anything that happens to your computer or internet connection during or after following these instructions. While this worked for me, I make no guarantee that it will for you.
Instructions for Windows Vista:
1. Open an administrator command prompt
2. Run the following command (without quotes): "netsh interface ipv4 show interfaces"
3. Find the connection you are using in the list. Note the number in the first column of the table.
4. Run the following command (without quotes): "netsh interface ipv4 set subinterface X mtu=576 store=persistent" where X is the number from the first column of the table corresponding to your internet connection.
(If you want it to revert back when you turn off the computer, use store=active instead of store=persistent)
(You may be able to use a higher number instead of 576. Experiment.)
This also affected the reliability of loading other online games, such as RuneScape. (I don't play RuneScape, I only used it to test the reliability - before it wouldn't load, now it will)

The MTU can actually be mostly whatever you want without a serious issue, for ethernet LAN. Disparate MTUs on different machines are fine in that ethernet LAN environment, switches will fragment frames and by and large sheer bandwidth will prevail. Naturally the network plug and play methodology comes into affect, which will negotiate suitable MTU and MRU off peers through MTU path discovery. The idea is that should handle all issues, but you have a NAT router and your ISP is sometimes dim about ICMP response, and so MTU path discovery falls over.
For ethernet, your largest frame size is 1500, however there are circumstances where it would benefit you (where ethernet hardware permits) to use jumbo frames up to 9000. The main issue you will get with the MTU is when you are sending across something like PPPoA, as ATM in general will transmit cells of a size 5 + (48 * N). Taking into account PPP and AAL5 headers and the typical MTU of ethernet, a good figure then becomes 1478. PPPoE typically would prefer an MTU of 1492, due to the PPP headers. | |

To quote some random website:
The MTU must be set to the same setting on all your PC NICs and router.
^ If you don't do that, it will severely (and adversely) affect your network performance.
