When I had OpenSuSE 11.3 installed originally, I never had any slow internet connection until I erased the hard drive and went to 11.4. This is what my configuration looks like on /usr/sbin/iwconfig:

The device I am using is a D-Link DWA-160 which is running the ar9170usb driver (and did on the previous version)
These are the steps I did:
Disable IPv6 from the global tab on Network Settings
Set DHCP version 4 only in dynamic address in address tab
Used the anti-IPv6 switches in firefox making these changes
network.dns.disableIPv6 change from false to true
network.http.pipelining change from false to true
network.http.pipelining.maxrequests change from 4 to 8
Added ipv6.disable=1 in DEFAULT_APPEND in Bootloader (I couldn’t find bootloader _APPENDS that was stated in another forum)
Switched from ifup to NetworkManager for Network Setup Method
Reinstalled OpenSuSE 11.4 with Ubuntu 11.04 (to see if it was OS issue) and it still didn’t work, so I switched back to OpenSuSE 11.4
Is there anything I did wrong or do I need to do anything additional? I tried giving you as much details I can and tried looking in other parts of the forums for the answer and I still can’t get the speed of web browsing or any downloading fast like it was in the past. I appreciate any help.
