Yes, all cables have been replaced, everything is now CAT6aAre all old cables replaced with new cables including those connected to both routers and the NAS?
^ I'll assume so unless told differently. So all cables and the switch were replaced. That's good, now you have a proper physical level infrastructure which a LAN should have.
Next, we look at the IP scheme. The diagram leaves many questions. Let's dig in. The following devices are outside of Router A's DHCP range but not marked as static on the diagram. So I'm going to ask:
Next, the only DHCP range (192.168.0.2 to 192.168.0.30) you have on your network diagram comes from Router A. You said Router B has DHCP disabled but would you recheck that? We must know for sure:
- Is Router A on a static IP address?
- Is the NAS on a static IP address?
- Is PC1 on a static IP address?
- Is PC 2 on a static IP address
- Is Chromecast on a static IP address?
- Is the Printer on a static IP address?
We are looking for possible IP address conflicts, whether or not a wireless device is being issued an IP address by router B which it has to drop and pick up a new IP address when it moves within range of Router A, etc..
- Is Router B setup to issue IP addresses via DHCP?
- See HERE. Which version is Router B (TL-WR0146ND); is it V1, V2, or V3?
Now watch the following video and then ensure Router B (TP-Link TL-WR0146ND) is correctly configured as a wireless access point (WAP) to Router A on a wired (not wireless) connection either in access point mode or manually configured.
You can reach out to the TL-Link community https://community.tp-link.com/us or contact TL-Link directly https://www.tp-link.com/us/support/contact-technical-support/ for further help configuring Router B (the TP-Link TL-WR0146ND) as a network access point.
- Yes Router A has a static address 192.168.0.1
- NAS, PC1. PC2, Chromecast and Printer all have static addresses assigned by router A based on their MAC address - it says so on the schematic.
- DHCP is disabled on router B.
4. As for the router B setup, my configuration was the one shown as second on the video - i.e. router B is connected to router A via LAN (not WAN) port and DHCP is disabled on Router B.
The TP link community will not help as the router does not run official TP link firmware. I flashed it years ago because the original firmware would not let me change the IP range to 192.168.0.x, it only allowed to use 192.168.1.x
I also experimented with enabling DHCP on both routers (just within different ranges) The network works, however, the main issue remains unsolved. In this case the IP address of the wireless device changes when switching from wifi A to B and back to A, yet the wireless device still does not see the wired devices for some 8 minutes.
Would it make any difference if I turn off DHCP on router A completely and only use DHCP on router B? (until now it was the other way round)
I am unable to set router B as an access point using method A from the video - LAN port on router A to WAN port on router B - not sure if I'm doing something wrong?
