Not a long post here. I just wanted to share the fact that the HTC Titan has a little bug (highly likely to be software-related) which results in the quality of the WiFi connection being a bit iffy; that is to say the phone connects to a network fine but after a little while is mostly unusable and may require frequent toggling of the WiFi option between off and on. A Windows Phone update via Zune didn’t seem to address this problem.
The ‘fix’ I found is that if you turn your data/3G connection off, the WiFi works fine. So the issue is some sort of interference between the two signals, most likely through some software problem. It’s certainly inconvenient for some to have their data connection totally off at home as this will halt the delivery of MMSs, so hopefully a permanent fix will be available which will allow the two to co-exist; but for now just turn off network data when using WiFi.
I don’t know if this affects all Titan owners but certainly a number of people have alluded to it online. Someone demonstrated the issue on YouTube too:
28 November 2011: I contacted HTC Support (Europe), and I found it a little bit incredulous that they think it’s normal to switch data off for WiFi. As far as I know all other smartphones allow both 3G and WiFi to be on simultaneously. This allows MMSs to come in while on WiFi.
18 May 2012: Microsoft seem to be aware of the problem (since Feb) and are working on a fix. It’s a Mango OS problem as it affects several WP phones; most likely all those which have had the Internet Sharing function used.
