How to set up the network correctly?

Question

DHCP

Hello. After googling a little about my problem, I found this article. Decided to write here to share my experience. I am setting up a network in Spain (I indicate the country so that it is clear that not only in Russian-speaking countries there are problems of my type), there is by no means everywhere fiber optics. So .... There is a network, the main router is connected via VDSL to the provider, IP did not change, left 192.168.1.1, aka DHCP. The remaining six routers are TP-Link TL-WR 841ND. The first router is connected to the main one via the LAN port, IP 192.168.1.2 and DHCP is disabled, the router is located on the first floor. The second and third routers are connected to the LAN ports not to the main, but to the first router and are located on different floors, on the third and fifth, their IPs are 192.168.1.3 and 192.168.1.4, DHCP is disabled on them. The fourth, fifth and sixth routers are connected to the first, second and third routers via WDS, thereby expanding the coverage area, IP of these routers 192.168.1.5, 192.168.1.6, 192.168.1.7 are installed on the second, fourth and sixth floors. The names of wi-fi networks are different on each router (maybe this is the whole problem, but I'm not sure). So, the building is a hotel, but small, 15 rooms, customers are constantly changing. The task is to make wi-fi throughout the hotel as stable and better as possible. Phones, tablets, laptops are connected to all networks, all via wi-fi. The problem is that wi-fi works stably only on the main router, it disappears regularly on all the others - for about two days and you can connect to the network, on phones and tablets it shows that there is Internet, but more than one site does not open. When connected from a laptop, a limited connection is visible. Sometimes a reboot helps, but not always. I understand that these routers are not quite a professional solution, but .. .. I work with what I have. If anyone has delved into the described network and has ideas, I will be very grateful and grateful. Can I increase the Address Lease Time value in the DHCP settings? Or make wi-fi network names the same for all routers and with the same other parameters? In general - I will be grateful for any practical advice (buying more expensive equipment is not considered)

Answer 1

Artem, why shoot then? They are configured by WDS because there is no way to lay a wire to them.

Answer 2

If it is not possible to lay wires, then you can try ethernet over power.

Answer 3

start diagnostics by pinging all routers on the network. further will be seen.
