I just had a looked at some at the electronics store, and found these options:
1. Netgear Aircard 785s; Mobil 4G Hotspot Netgear; usage 10 hours on battery, standby 300 hours; supported network bands 4G LTE FDD, 4G LTE TDD, 3G 850 2G 900; wifi 802.11b/g/n; 127 gram; micro-SIM (very convenient: so I can carry it in my pocket and use anywhere if I have a mobile internet with a micro-SIM)
2. Zyxel wireless router AC750
3. Zyxel indoor router LTE3301; 350 g
4. Netgear AC750
5. Netgear AC1200; 385 g (a bit too heavy)
6. Netgear N300
7. From Amazon: https://www.google.se/search?q=%22router%22+hootoo&oq=%22router%22+hootoo&gs_l=psy-ab.3...6573.6940.0.718.104.22.168.0.0.0.0.0..0.0....0...1.1.64.psy-ab..0.0.0....0.mJZE4C397Bc
Which one should I choose? The first one seems a good option.
I received advice here at EE earlier that I should always use a travel router when using public wifi to get better protection. However, I'm not sure about the definition of travel router: is it just a wireless router or is it something special that is called travel router? The shopkeeper didn't know anything about the term travel router, only wireless router.
Most often when I use public wifi at hotels it's wifi and not wired, although it happens there is wired also.
The shopkeeper told me that the main criteria that determines the capacity and price of a wireless router are these:
Number of outlets for wired connection
Frequency (higher frequency, like 5 GHz, gives more assurance there will be no interference with other electronic equipment like microwave or TV etc. as opposed to lower frequency like 2.4 GHz)
Furthermore, the shopkeeper said it's possible for me on some wireless routers to restrict how many devices can connect to my router (which would be a very good security measure: just restrict to my own number of devices).
What do you at EE think, would number 1 or 7 be the best option for me? Number one priority for me is security and portability. The devices I will be using are a Windows 7 laptop, an Android phone and maybe more later, like Macbook and Linux and Windows 10 laptop.
