Why can't get to the admin panel for Openwrt router mr-3020 wifi?

Will start from the beginning order:
Equipment no. :) Was held at the cable from Rostelecom in the room, connected directly to the laptop. The provider gives the Internet on binding to WT ( without the logins, passwords).
I bought the above router registered this router with your ISP. the firmware has not yet touched. Earned online with computer by wifi. Phone hangs or authentication or obtaining IP, wifi konekta phones with the router and not seen. On a standard TP Link-ovsky firmware could not get to the admin panel via wifi, provided that the cable provider plugged into the router. While cable ,not like you can go in.
Router I need so far, the main destination. To take traffic from the ISP via ethernet cable and give it a few Wi-Fi AP c different rights.
Sew the router OpenWRT luci 15.05 c on Board. Conectus ethernet cable to Romero, I go through the browser to the web admin, see only a lan interface. No Wan and the ability to add wan interface is not found. Set up wifi, disconnect ethernet cable, conectus wifi. The connection is, the ip the computer got. Try to log into admin area, zero. ping 192.168.1.1 is silent. Again connect the cable - open the admin panel.
If the switch on the lan DHCP client, the router picks up the ip from the provider distributes the Internet, but without resetting the router settings in the admin panel to get not possible(the ethernet port in the router that one, consequently my PC to the router only via wifi can preconnecting).
Such trouble was observed up to flashing the router to the standard firmware Pinkowski: can't login to the admin panel via wifi. just don't pingoud standard ip admin panel.
Another problem ( observed in the standard firmware, and openWRT) as soon as the router starts to adopt the Internet by the ethernet cable( Internet Rostelecom, Novosibirsk, snap on MAC logins passwords is not), he will not let me on wifi more than 1 client. Computer connect, the phones do not go. Until I set lan to DHCP client phones safely connected to wifi.

Solution
Will start from the beginning order:
The story adds to the sadness, because everything is a lot more to ask and more commonplace.
Equipment no. :) Was held at the cable from Rostelecom in the room, connected directly to the laptop. I bought the above router registered this router with your ISP. the firmware has not yet touched. Earned online with computer by wifi. Phone hangs or authentication or obtaining IP, wifi konekta phones with the router and not seen. On a standard TP Link-ovsky firmware could not get to the admin panel via wifi, provided that the cable provider plugged into the router. While cable ,not like you can go in.
Sew the router OpenWRT luci 15.05 c on Board. I go to web admin, see only a lan interface. No Wan and the ability to add wan interface is not found. Dogpile before switching wan ports. I'm not exactly where to switch ( ethernet port in the router physically one, it Pisano wan/lan.), but you never know what's settings occurred. Adequately similar menu with any signs of life wan not found.
Router I need so far, the main destination. Take traffic over ethernet and give it a few Wi-Fi AP c different rights. It is sad that elementary hand does not turn to adjust.
Then things are even simpler:
1. Go to Network-Interfaces
2. In front of the LAN interface, click Edit
3. Check that you installed the static address of 192.168.1.1, mask of 255.255.255.0, tick Disable DHCP for this interface was removed(!). In the fields Start exhibiting the first address of the subnet (default 100, that is, the distribution of addresses will begin with addresses 192.168.1.100), the Limit reflects how many addresses after the initial will still be distributed. Default 150. That is at 192.168.1.100 192.168.1.250.
4. Go to the tab Physical settings and remove the checkmark from Ethernet Adapter: "eth0". Tick, you should only stay on the Wireless network. By this action, we disconnect the lan port from the bridge and now we will turn it into a wan port.
5. Click save & apply.
6. Now connect any device to the router via wifi. Via cable we now do not see and address for dhcp do not get it.
7. Go back to Network-Interfaces. Click Add new interface.
The name you specify WAN Protocol, choose PPPoE and put kryzhyk opposite Ethernet Adapter: "eth0". Save & apply.
8. Again, go to Network-Interfaces-WAN-Edit. Enter the login name and password from the agreement with Rostelecom and plug-in cable from Rostelecom in the lan port.
9. Go to advanced settings note jackdaws Bring up on boot, Use default gateway, Use DNS servers advertised by peer.
10. Save & apply.

After that, you are on the main admin page should appear WAN IPv4 Status, which will show statistics on the current connection. If Rostelecom is no reference to MAC address.
Well, for all wireless devices will begin to work the Internet. - Lesley52 commented on July 9th 19 at 10:22
Another small tip: now to elaborate on the issue you have created yourself an answer, and it submitted additional information. It would be better to edit and add to the question itself, then all users will immediately see a complete picture of the problem. - Lesley52 commented on July 9th 19 at 10:25
Roger that, cap corrected. in the evening coming home from work, I will act.
Another Supplement, I have apparently not Rroe for login there is no password, but bound to the MAC address comes from the service provider. The router is already registered ( native MAC linked), if you need preregister on a different MAC, which can appear after the correct settings.
PS: very grateful for Your attention :) - Lottie27 commented on July 9th 19 at 10:28
if not pppoe, so just dynamic ip provider gives the MAC address. - Lesley52 commented on July 9th 19 at 10:31
Thank you. in fact, the instructions written Above is not so simple, I'd long searched for the answer, if you wouldn't have given up the search and started to sin on the sloppy router.
The difficulty lies in understanding the architecture of the openWRT - breeches, interfaces. I would like to read more or less nobska article on this subject, so far nothing found.
Get back to BUSINESS. Everything is configured as You said. Two user interface are there, but Internet connection is not present. Are you sure that there should be no links between wifi and lan ? - Lottie27 commented on July 9th 19 at 10:34
and another question, how must be configured the firewall, can it not to start? - Lottie27 commented on July 9th 19 at 10:37
Send a screenshot of the Status tab-Overview and Network-Firewall-General settings.

Via wifi address distributed? The devices connect correctly? - Lesley52 commented on July 9th 19 at 10:40
Thank you, Constantine, understood. Long studied the menu luci was Gmail all to what hands get messed up, swiper router again fought and found. There by default the lan interface (the one for wifi ) to firewall were not red and not green and grey rule, supposedly to drive most firewall rules. changed to green.
The second day of normal flight. It is a pity that the basic answer you gave in comments and not answers. Thank you, very helpful advice with a gap bridge between wifi and ethernet.
I'd love somewhere to read how all breeches work and why they are needed.. and also why bridge the Internet prokatyvaetsja. - Lottie27 commented on July 9th 19 at 10:43
by : openwrt has an official wiki wiki.openwrt.org there you can read all about openwrt, but the most recent information in English.
Bridge by and large just brings together different interfaces into a single virtual. Therefore, it is called a bridge between the different interfaces. - Lesley52 commented on July 9th 19 at 10:46
: Wiki openWrt tried to vkurivat.. from different sides)
"The bridge between interfaces" unfortunately not enough about what speaks to me, because it is not entirely clear what the interface.. what's his scope of authority, for which he is responsible, and what can't. Where the end of a zone of access of a client connected to the interface, i.e. the General gist of the interface and logic.
For example, for me it would be logical that in the interface will operate all connected clients and the server, the interface can pull. And if in one interface bunch of users having relative access to each other, and the other interface, the second group of users, and access to the Internet, that first group to give access to the network of the second group ( and the Internet which she has) it would be necessary to build a bridge between these interfaces. But it turned out the bridge had first to break, and then two unrelated interfaces have access to the Internet....
For a beginner, not really groping in the networks, but having a desire to understand most of the information on the wiki at openwrt looks rather dry, I do not understand the skeleton, the structure that after that on that tied. Well, if there is a sane education on the network protocols and structures of networking in General.
Of course you can poradovatsya via a wiki in which all abrowser actively kicking the young apprentices to spend a lot of time(perhaps weeks), I have relatively fine with English, but to build the whole picture relying only on console commands ( which Vicky reveals the logic of the system) is very difficult. now, if to stir up the article on Habr in style of illustrative examples of cases configure openwrt in the luci and the results of that now and how it works, it would be megapolises guide for beginners! even in English. - Lottie27 commented on July 9th 19 at 10:49
ps I have a lot of plans to work with openWrt, I have already bought a second, identical router))
would appreciate links or code words for Google to hunt useful information for LAMER like me superficially know what ip, mac, server and client. - Lottie27 commented on July 9th 19 at 10:52
: If you mix the concept of the interface of the bridge with the concept of differentiation of user access to subnets, you'd better start to organize the knowledge by studying the OSI model. This will help Andrew Tannenbaum and his book "Computer networks". To this base of knowledge from wiki openwrt will go better. - Lesley52 commented on July 9th 19 at 10:55
thanx - Lottie27 commented on July 9th 19 at 10:58

put on all devices (except the router) automatically obtain the settings, most likely the conflict of IP addresses happens

Initially, let's clarify what you have equipment other than the router MR3020 is present and for what purpose you planieta to use this router, exactly which version of OpenWRT you flashed?

Can a little povangovat and to assume that once you have connected to the ISP Rostelekom, you set the Eltex optical modem, Huawei or EciBfocus, where there is no wifi, and using the MR3020 router you want to connect wireless devices to the modem.

Also, if I remember correctly, on mr3020 default lan and wifi interfaces are not integrated in the bridge (bridge), as this is considered a router, either lan or Wi-Fi will look to the Internet.

For clarity, the examples assume that your optical modem from Rostelecom has an ip address of 192.168.0.1 and hands out addresses by dhcp range from 192.168.0.100 to 192.168.0.200.

So
1. Disable the router from rostenkowski modem, if you have already managed to connect them by cable, in order to avoid confusion.
2. Reset settings router mr3020 to the initial state.
3. Go to admin panel of the router at 192.168.1.1, set a root password.
4. Go to menu Network-Interfaces. Most likely you'll have two interface LAN and WAN. To the LAN interface will be your cable connection, and WAN wifi.
5. WAN delete - click the Delete button. You can then click Save at the bottom (but not the Save & Apply)
6. Now, edit the LAN settings - click Edit.
7. Install Protocol: Static address IPv4 address: 192.168.0.2 (as you have noticed, this is a free address from the subnet rostelecoms modem), IPv4 netmask: 255.255.255.0 IPv4 gateway: 192.168.0.1, DNS: 192.168.0.1
8. Just below, check the box near "Disable DHCP for this interface." We turn to the distribution of addresses on mr3020, because, as we discussed, distribution of addresses rostenkowski modem. You can then click Save at the bottom (but not the Save & Apply)
9. Go to the tab Physical settings.
10. Check boxes Bridge interfaces.
11. Below opposite the Interface note jackdaws Ethernet Adapter: "eth0" and Wireless Network: Master "OpenWRT"
12. You can then click Save at the bottom (but not the Save & Apply)
13. Go to Network-Wi-Fi, opposite the wireless network click the Enable button and then Edit.
14. Set the channel and power choice.
15. In the ESSID field, enter the name of our network Mode: Access Point. Below make sure the checkmark is in front of lan.
16. Tab Wireless security - Encryption: WPA2-PSK, Cipher: AES Key: the password of your network.
17. Now finally click Save & Apply.
18. Podcacher router cable to modem rostelecoms.
19. On any wireless device, find the network connect password that you entered above.
20. Make sure that you correctly received an ip address from the subnet rostelecoms modem 192.168.0.0/24.
21. Now you can try to access the admin area of the mr3020 router at 192.168.0.2
22. The Internet just needs to work.
23. Check that the number of employed wifi devices could be more than one :)
