I can confirm that this also affects the Netgear MA521 PCMCIA card using the rtl8180 chipset - I have excellent reception status using ndiswrapper under Hardy, however see only 5-10% under Intrepid (~3' from the router).
I also note the following, possibly related, symptom with the open source driver in Intrepid; once connected to a wireless network I am no longer able to manually scan for wireless networks using "iwlist scan" (note that I am able to scan before the connection is made). -- Intrepid Ibex: Belkin F5D6001 (rtl8180): Weak WLAN - Signal https://bugs.launchpad.net/bugs/290325 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
