Hi LTT lads & Ladies,
First post long time viewer.
I've been having issues with my network setup for some time now and it just got to the point I just don't have a clue what to do next.
When we moved into our house (Renting) we had to get NBN installed due to the copper lines being cut. The ISP sent us one of their provided routers (AudioCodes MP264) which worked fine but had a poor signal when outside (not even 50ft from the router).
I looked around and decided on the Asus RT-AC5300 as a replacement as I thought it was NBN ready?
Upon setting it up I would only get about at best half the bandwidth available (100/50 connection) and could not for the life of me figure out the VOIP.
After a quite a few calls to the ISP, they pretty much gave me little to no help in regards to setting it up due to it not being their own router. So after a few days of mucking around, I decided to use the ISP router as a modem and connect my Asus router as an access point. (ISP router Wi-Fi turned off). This worked well for a few months then all of a sudden my connected devices on the 2.4 GHz band just started disappearing from the devices menu on the Asus router (would show on initial login then just disappear off the device list) but still showing on the ISP router.
What I mean about them disappearing is they were connected to the Wi-FI but not discoverable i.e. smart TVs, Wi-Fi printer, Raspberry pi. They still had working internet connection on their end.
So to combat this I ended up having to disable the 2.4 GHz band on the Asus router and run them back off the ISP router. I spoke to quite a few techies in the local area and none of them had an Idea what was happening. I ended up taking the Asus router back to the place of purchase to have it checked and to also have the antennas looked at as there were a few looses ones. They couldn’t find an issue but replaced it as the loose antennas were an issue from the factory.
Still, had the same issue.
Last weekend I decided to turn off the Asus router as I only had 1 device attached (this laptop I’m currently using).
So now I can't access the ISP router settings through its own Wi-Fi unless I connect up the Ethernet cable or log into it via the Asus router (See pic attached)
I also have a NAS attached to the ISP router and can access it through windows but can't log into the Web browser unless I do the same above.
I am at a loss as to what to do now as this is driving me up the wall.
Side note: I purchased a CISCO SPA112 ATA for the VOIP setup to the Asus router.
ISP router has been reset to factory
current laptop has just had a clean install of windows 10.
