thanks, akoellh and framp!
i tried this:
Remove all files /etc/sysconfig/network/ifcfg-something except ifcfg-lo and ifcfg.template and restart the networking services with “rcnetwork restart” as root.
but found that this did not fix the problem. my connection speed was still low (1Mb/s) and the connection was still dropping off sporadically but automatically (if not instantaneously) reconnecting at the low connection speed. one observation: the connection speed does not stay constand, but rather fluctuates.
so i decided to re-run this:
collectNWData.sh
this time, i got these error messages:
!!! CND0180I: The system can’t ping external IP address 195.135.220.3
!!! CND0150E: There might be problems with the default gateway definition 192.168.0.1 on interface wlan0
then i went to framp’s site to see what fix to apply for these particular error codes, but here’s what he had to say about the first one (CND0180I)
Cause of error message
This is an informational message because there are a lot of possible causes of this error. collectNWData should have written more detailed error messages.
Problem resolution
Look for other errormessages and visit the corresponding pages in this WiKi.
so i did just that, and here’s what he had to say about the second error message (CND0150E)
CNProblem fix
For a SuSE distribution you can defined the default gateway as follows:
Network devices -> Network card -> Change -> Select any network card -> Routing -> Defaultgateway
You have to define the router which is used by the client as the default gateway. If the client is connected directly to a DSL modem kinternet handles the assignment of the default gateway which was passed by the ISP. If this doesn’t happen you have to check the modem configuration.
the only issue here is that in network settings, i have “user controlled with network manager” selected for my network setup method, which means that i cannot set a default gateway as framp suggests one should.
so i did a little more digging to try and give you folks more details around the problem i’m having. to that end:

one last thing, when i try to manually set the connection speed with:
sudo /usr/sbin/iwconfig wlan0 rate XXM
immediately after doing so, i checked the connection rate by this:
/usr/sbin/iwconfig wlan0 | grep Mb
and also by clicking “connection information” on the tray, both of which reported the connection to have changes to 54Mb after i had changed it to that. however, after opening firefox the connection dropped and would not automatically reconnect.
any help you can provide is greatly appreciated, thanks!!
