sorry for letting you wait for an answer for so long.

The first line is about your wired network adapater, Realtek RTL8111/8168
B. The Linux driver name is r8169
The second line is about your wireless network adpater, Broadcom BCM4313 802.11b/g/n
. The string 802.11b/g/n
is a technical abbreviation which tells that your card supports ethernet standard 802.11 b - g - and n, which basically is good and up-to-date.
The driver name is brcmsmac

The iwconfig command seems to confirm that basically your Broadcom wlan adapter works fine and that your wlan connection seems to work fine, too.
"Mode managed" means managed by Network Manager.
The current bit rate will vary depending on how much data is being transferred at a given time. It is the bit rate between the Broadcom card and your DSL router. The displayed bit rate may or may not be correct. With some wlan adapter iwconfig seems to be unable to determine the correct bit rate. At least for some adapters iwconfig and my DSL router always disagree on the current bit rate.
The link quality again tells you something about how strong the DSL router wireless signal is. 50/70 should be good enough.
So your Broadcom card should not exhibit any problems communicating with the DSL router.
All this is pretty unrelated to the up- and download speed which you will have between your DSL router and your internet provider. And they are the only ones who can really analyze whether a line works as designed or whether there are distorting signals on the line which will slow down the speed or even lead to interruptions.
So from my point of view, based on my (limited own) experience, your Broadcom wlan adapter seems to be working all right and there does not seem to be a serious reason for changing the Broadcom driver software.
