|International Server? Where are you, and where is this "international server?" |
As to specifically why the download speeds are half on wireless vs. wired , well, depending on what WiFi 802.11 spec you're using (802.11b, 802.11g, 802.11n) - wireless connections are generally slower than wired connections due to various reasons like interference & obstructions of the WiFi signal, WiFi overhead (OFDM, DSSS) and wireless encryption. I'm assuming you have WiFi encryption enabled as well like WPA2 AES? With the WiFi encryption, the signal needs to be coded & decoded at the endpoints in the data transfer, which will slow the whole process down. Your WiFi connection is 54 Mbps/802.11g, which is about half as fast as a normal 100 Mbps wired connection right off the bat. But that 54 Mbps is only on your WiFi LAN – over your wireless in its optimized state. Its 100 Mbps on your wired Ethernet – wired PCs and router.
Then your 54 Mbps WiFi or 100 Mbps wired LAN speeds get bottlenecked down to a rather slow 4 Mbps DSL connection. Add in your 3 PCs fighting for bandwidth as they go out to the Internet and look for updates for OSes , AV updates, Adobe Reader & Flash player updates, Media players, iTunes, GoogleUpdater, JAVA, etc service running in the background.
Then out there on the Internet there are all sorts of network traffic issues over your ISP’s network and the Internet Nodes and finally down to onto the network of the “server” that you are downloading from. Then add in possible server issues ON the server itself; add in multiple users trying to get data off that server at the same time and all the users online at the same time...there’s a lot going on in the background.
MOOOOooove! OH and you're welcome!
