ASUS WL-330N3G Mobile Router First Impressions

I own a samsung Galaxy 551 smartphone, a Samsung Galaxy Tab 750 tablet (Galaxy Tab 10.1 as it is known in most countries), a Nokia E63 smartphone and a company provided business laptop. I do not have a personal laptop or desktop since my laptop got stolen last year. As for connectivity I use a Tata Photon USB dongle which I use in my laptop only. For my android phone and android tab I use a vodafone edge sim card which I share, and use a company provided on my nokia which has no internet. So my current setup has a costly broadband plan which I use mainly for office work, while I have a sub optimal speed for my droids and no data plan for my Nokia.
The natural solution to this would be to get a wireless router for my Tata Photon, so I can share the bandwidth between all my mobile devices. This would also enable me to change my slow speed but high capacity mobile plan to a lower capacity (but much higher speed) 3G plan at similar price.Then comes the big question: What router to buy as most wireless routers are compatible with ethernet networks only. Normally I do research on the net before going out on a purchase like this but this time I did not, planning to trust the guy who would sell me the router.
After frantic searches in at least 8 shops in the Chandni Market in Kolkata, finally one gentleman from R.R Infotech said he can get me what I want. He got me this particular router from somewhere else while I waited for 30 minutes. I was little sceptical to this product but having spent more than an hour in the market trying to explain 8 different shopkeepers what I want, I decided to take a chance and buy this stuff. The shopkeeper assured that if I cannot configure myself, he will provide customer service on phone.
After turning the router on, as expected the router did not work! After opening the router configuration screen from the browser, I saw that it is dialling a Chinese ISP. I saw that Tata Photon was available on the dropdown choice, and selected it, and after 3 4 minutes it connected gracefully.
This is initial post and too early for a review. However a few points based on using it for 12 hours.
a. Configuration is very easy
b. Maybe my fault but it hung a couple of times and I had to power off and back on to get it working
c. It is small enough to fit in the pocket, yet it does not have a battery to qualify as a mobile router
d. Claims 300 square meter range (Not Tested)
e. Claims 150 Mbps speech (Not Tested)
f. Multiple modes as wireless router for ethernet, 3G, and wireless repeater amongst others
