Hi everyone. I hope someone can help with this issue. AT&T technical support seems stumped.
I currently have the following network hook-up:
On the Cable Modem:
Fiber -> BGW320-500 (5G ethernet) -> SL-SWTG215AS (port 6, 10G max)
On the Switch:
Port 1: 1 of 2 link aggregation (5G max) [trunk 1]
Port 2: 2 of 2 link aggregation (5G max) [trunk 1]
Port 3: Orbi to extend wifi (1G)
Port 4: Office Computer (1G)
Port 5: RT-AX86U 2.5G LAN port
Port 6: BGW320-500 using 10GBase-T SFP to Ethernet plug (SL-10GE-T)
On the RT-AX86U:
LAN 4: Port 1 switch (1 of 2. trunk1)
WAN: Port 2 switch (2 of 2, trunk 1)
2.5G: Port 5 switch
On the Orbi:
Internet: Port 3 switch
Lan1: NAS1 (synology port 1)
Lan2: NAS2 (synology port 2)
The switch is set up with two VLANs (untagged, unnamed):
VLAN 1: Port 6, trunk 1
VLAN 2: Port 3-6
BGW320 Set to IP PASSTHROUGH, all wifi turned off
DHCP done in RT-AX86U using Merlin firmware , all wifi turned off
ORBI (RBR50) in AP mode connected through the switch supplies wifi to the network with the aid of a satellite ORBI companion (RBS50).
All cables to/from the switch are 3ft cat6 cables. Cable from the NAS to ORBI are a little longer (6ft)
All firmware is current.
A few obvious observations and why the network is the way it is (mostly from evolving over a few years):
1) The ORBI is a little old. It can't possible supply 5G wifi speeds. The best it can do is 500ish...maybe 600 in ideal conditions.
ANS: Yes, I understand. I am in the process of updating to faster speeds, working on this "next".
2) The RT-AX86U can already provide WiFi 6...forget the ORBI.
ANS: I agree, except that the range won't work for my entire house. I have to use mesh or some sort of extender product. I originally used the RT-AC86U for its on-board VPN and routing capabilities only and used the Orbi's for wifi. I just recently upgraded to the AX86U. Maybe I can get rid of the ORBIs but I did not want to take on that work just yet.
The RT-AX86U currently reports 43 clients connected to my network.
Sorry about the long setup to my questions.
Here is my question:
I am having an annoying connection problem in which the BGW320 disconnects from the WAN (flashing red, then back to solid white). Sometimes for just seconds at a time. Sometimes for minutes or hours at a time. Most of the time when I have the issue there is no outage in my area. Sometimes it seems like the modem's errant behavior is foreshadowing an AT&T network outage. Most of the times when it happens it just seems like the modem is misbehaving. It doesn't happen all the time continuously; sometimes everything is working great for a few days or weeks and then the modem gets on the fritz again.
The AT&T tech support is not sure what to make of this modem behavior. They can see on their side that I am having the disconnect issues and they can see that fiber line is working "perfectly". It seems like there is something faulty at the modem, except they have replaced the modem twice already.
Is it possible that the switch could "overwhelm" the BGW320? How do I know if this is the case? It's surprising that something connected to the ethernet ports of the BGW320, even a faulty device, could make the entire modem go down for seconds, minutes, or hours at a time. If the switch is overwhelming the modem, is there something I can do to?
Any ideas are welcome.
Thanks,
Jose
