In openSUSE 11.1, laptops installed with the BCM4311/BCM4312/BCM4321/BCM4322 Wireless LAN cards like the Dell Inspiron 1525 do not have drivers installed and hence do not work out of the box. In Dell this Wireless card is labelled as “Dell 1395 Wireless card”. Broadcom has released a linux version of its driver both 32-bit (x86) and 64bit (x86_64) editions for BCM4311, BCM4312, BCM4321 & BCM4322 Wireless cards. A 1-click install Yast Metapackage file (YMP) is available for install from Packman which makes it easy to get your wireless up and running in no time.

Maximum Transmission Unit (MTU) the size (in bytes) of the largest packet or frame that a given layer of a communications protocol can pass onwards. The MTU may be fixed by standards (as is the case with Ethernet) or decided at connect time. A higher MTU brings higher bandwidth efficiency. However, large packets can block up a slow interface for some time, increasing the lag for further packets.
