By default the HD2 wifi setting is set at WLAN 802.11b. It should be set to 802.11g or 802.11n.
b is the shortest distant of transmission/reception and n is the longest.
HD2 does not allow you to do it directly. Unfortunately you need to change the registry to do that. You can also use one of the tweak programs to change the wifi setting.

You need SKTools to do it. Download SKTools from here: http://s-k-tools.com/index.html?m_downloads.html
You can always use the free Trial version for this purpose.

At SKTools, choose Tune Up then at the bottom tabs goto Network. At WLAN 802.11 G support select Yes at the top window. You are now set to enjoy a faster speed and stronger strength signal on your WiFi connection

The HD2 stock ROM sucks. One of the reason is WM6.5 is a very heavy program carrying many unnecessary applications, thus slowing down the HD2. Chefs of cooked ROM removed many of these unless applications and bugs thus making the ROM super fast and bug free. You only need about only 20MB of memory to run HD2 efficiently. The photos, video and music folders will take up most of the memory and should be transferred to the SD card.
Flash cooked ROM is the best solution.

It took Microsoft a long time to get WM6.5 sorted out. When it first came out WM6.5 had many problems. We can expect WM7 to be the same. By the time WM7 problems are resolved, it would be time to get a new phone, 2GHz processor

Microsoft is trying but their WM7 is a bit too little and too late to beat iPhone OS4 and Android. It is a pity as they have ahead start for many years.

You need to reformat your SD card ASAP. If you don't very soon it will disappear completely and you will have no opportunity to backup the data. It has happened to me before but fortunate I always backup my SD card.

You only need to reformat the SD Card. If you could!

Try the Soft Winter Storage Tool program to recover your SD Card. This is a powerful SD Card progam for the device. Best of luck

It is the price we early adopter has to pay. Pun intended.
