Problems with the Droid X 3G Mobile Hotspot: dropped connections

For the past few months, I've been using my Motorola Droid X as a 3G Mobile Hotspot. Most of the time, this feature works fairly well. However, I've recently started experiencing more problems. Specifically:

• It drops a connection and the 3G Mobile Hotspot service stops
• It freezes up and I lose access to the Internet even though the 3G Mobile Hotspot service is still running

I've tried resetting my phone and experimenting with various settings, but nothing seems to fix these intermittent problems. I've tried the following steps outlined on the Verizon user forums, but I don't want to go through this process every time I use my Droid X as a Mobile Hotspot:

Step. 1 - Ensure WiFi is disabled. (instruction below)

Step. 2 - Try switching the hotspot channel (Step 6 in the article under channel)
***To access settings, 3G Mobile Hotspot must be disabled (Off).

Step. 3 - Try changing the encryption

Step. 4 - Try relocating the device. (Something in the immediate location could be affecting the service received)

Step. 5 - Soft reset (power off the device, pull the battery out for 20 seconds and place it back in)

I'm wondering if people who own a MiFi are experiencing similar issues. Perhaps a dedicated Mobile Hotspot like a MiFi is a better option than using my smartphone. Maybe it's time to upgrade to a 4G device. When's the 4G MiFi 4510L coming to Verizon? When's the HTC ThunderBolt 4G smartphone arriving? Maybe I should just get a 4G MiFi from Sprint now.
