A source of information

Q: How to unlock this device?
A: Find out the IMEI of your device (this information is on the label under the back cover). Calculate unlock codeaccording to algorithm 201 via this utility . Insert the SIM card of another operator (ie, not the one under which it is locked) into the device, then connect to the device via WiFi, or through the LAN port, go to the browser via the link http: //homerouter.cpe and in the window requesting the code, enter the code itself.
Q: How to use this router with unlimited tariffs Yota, MTS Unlimited, and so on?
A: First, you needchange IMEIand secondly installproshivka for "greedy" operators. After that, you can easily use the Internet at these rates.
Q: How does the E5186s-22a version differ from the E5186s-61a version?
A: Firstly, at E5186s-61a there is an aggregation of only frequencies of 2300 MHz (20 + 20). In the Russian Federation, with 2,300 federal operators do not work, sometimes (very rarely) regional ones work. With high probability, you will not be able to use the function of aggregation of channels on this router in Russia and in many European countries. Specify additionally, at what frequencies your operator operates.
E5186-22a works 100% in aggregation with any Russian and European operators.
Secondly, these models differ in frequencies. Version 61a - for Australia, Africa and some Asian countries, 22a - for Europe (including for Russia and other countries of the former USSR). This does not mean that the E5186s-61a will not work in Europe at all. All frequencies except the first (800 MHz at 22a and 700 MHz at 61a) are the same. This means that LTE will not work at 800 megahertz, the remaining frequencies (1800 MHz and 2600 MHz) coincide and will work without any problems. Since 800 MHz is a rather rare band (at least for Russia, and at least for now), this does not really matter. Accordingly, it is worth looking at the situation. If you don’t catch 800 MHz and you don’t need aggregation, or you don’t need it, you can save money and order the E5186s-61a version from aliexpress (or from somewhere else).
I repeat that 800 MHz, at least specifically in Russia, is not very widespread so far, so if you do not need aggregation, in most cases you can safely take the E5186s-61a. However, the 800 MHz range due to the relatively low frequency and, consequently, a larger coverage radius in the near future, is likely to be widely spread. If you live somewhere far from the tower and catches only 1800 MHz, then I recommend taking 22a, because it is possible that the 800 MHz range will soon open on your tower, which will help to increase the speed many times due to aggregation.
Q: Are the E5186s-22a and E5186s-61a firmware compatible?
Yes, the firmware is fully compatible. You can install either the E5186s-22a firmware on the E5186s-61a or vice versa.
Q: Where can I download the service firmware BV7R2C0update_21.282.99.80.00 - DOWNGRADE.gz.bin?
On MEGA(in the Original Huawei folder), there you can download this and others.
