Found that there are some maxis broadband users have the problem of only getting EDGE Signal with their ZTE modem recently. It can be solved with the following steps,

1. Please go to http://www.maxis.com.my/maxisbb to check if your ZTE modem need any upgrade
2. Open Internet Explorer and enter http://192.168.0.1, press enter
3. If you see your Network Type is showing EDGE,
4. Select Network Connect --> Manual Connect --> Disconnect, then press Submit
5. Select Network Select, and choose WCDMA Only (Not WCDMA Preferred)
6. Select Network Connect --> Manual Connect --> Connect, then press Submit
7. Select Home Page, you should see your Network Type have become UMTS or HSDPA if your are under coverage
8. Select Network Connect --> Auto Connect then press Submit

Hope this will solve your problem

If you choose WCDMA only, wouldn't you be left without a connection if WCDMA suddenly becomes unavailable? I thought if you chose preferred, then if WCDMA is not available, it will fall back to EDGE?

Yo, this happend to me before, i choose WCDMA preferred. But at that day connection/signal were very sux, it auto switch to EDGE..

You can try around. We have experienced when there got the HSDPA/UMTS actually, but it still switch to EDGE.
