Why do some Routers have different version numbers?
Sometimes a manufacturer will change some internal parts that will then require that different firmware version must be used. The version number of the product indicates to the owner which firmware version they need to use with their product.* Sometimes these new hardware versions are released because of a short supply of a part, or because an alternate part can be manufactured much cheaper, and sometimes a new version will represent some improvements over the original. It’s often difficult to find out which is which and quite often an older version will come back onto the market (eg if a supply problem with the original part has been fixed). In most cases it doesn’t matter a great deal which version number you end up with as they all have pretty much the same performance and features but there are exceptions to this so it pays to do some googling to find out as much as you can about a product to see if there are any known problems with any particular version number. *Warning: Uploadin
