THAT'S IT! My WiFi is working again. Good luck!
Thank you hugely for this tip. I've been struggling with my Dell Streak to resolve this issue, lots of other suggestions haven't worked (eg using other file explorer apps like ES File Explorer, Dual File Manager; via a terminal emulator which is given SU access; or going into the phone using SDK Manager from the PC) but this one did it.

I rooted the phone using an older version of SuperOneClick, the current version doesn't seem to work with the Streak, you need to go back to a version which uses the rageagainstthecage approach. v1.5.5 I think.

A final quirk for the Streak is that the file you need delete or rename is different to any other information I've seen - it isn't bcm_supp.conf or wpa_supplicant.conf, but simply wpa.conf, and is found in data/misc/wifi on this device.
