LAN Setting for Globe Wimax 2 Mbps Bundle for Windows

Some home LAN owners complain that Globe Tattoo@Home Wimax is not suited for LAN. They complain about not being able to access some websites or play online games when Globe Wimax is shared across a Home Network whether LAN or WiFi. They would usually complain about weak signal or not getting the bandwidth they were promised.

Ok, so we will deal with that issue today. So what is the problem? Is it a DNS issue? or No Connectivity Issue? It's none of the above. Calling 211 or Customer Service will NOT touch on the issue of MTU or Maximum transmission Unit. So read on...

Wikipedia Defines MTU as:
 "In computer networking, the maximum transmission unit (MTU) of a communications protocol of a layer is the size (in bytes) of the largest protocol data unit that the layer can pass onwards. MTU parameters usually appear in association with a communications interface (NIC, serial port, etc.). Standards (Ethernet, for example) can fix the size of an MTU; or systems (such as point-to-point serial links) may decide MTU at connect time.
A larger MTU brings greater efficiency because each packet carries more user data while protocol overheads, such as headers or underlying per-packet delays, remain fixed; the resulting higher efficiency means a slight improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data. In some systems, per-packet-processing can be a critical performance limitation.
 However, this gain is not without some downside. Large packets can occupy a slow link for some time, causing greater delays to following packets and increasing lag and minimum latency. For example, a 1500-byte packet, the largest allowed by Ethernet at the network layer (and hence over most of the Internet), ties up a 14.4k modem for about one second.
Large packets are also problematic in the presence of communications errors. Corruption of a single bit in a packet requires that the entire packet be retransmitted. At a given bit error rate larger packets are more likely to be corrupted. Retransmissions of larger packets take longer."
Well done and Thank you Wikipedia. So we will use this information from Wikipedia. The question now is how will you change the default 1500 MTU value to an optimized MTU value on Windows XP? There are several ways but we will use a Freeware MTU Tweaking Utility to automatically determine the correct MTU value that  is optimized for your PC.

This Freeware is called SG TCP Optimizer from SpeedGuide.Net.

In the Forth coming posts, I will show you how to use this great freeware to optimize your LAN.

  1. I just wonder if the 2mbps wimax is a portable one. We just called the globe office and ask about it, they said it is Wired. So, it's not portable if it is wired.

    I have a portable 1 mbps wimax, I dunno. maybe the person who we talked to is not an expert.
