Vumatel CPE Troubles

[Anonymous™]

Hey Guys,

I find myself with a peculiar problem that Vumatel wishes to wash their hands clean of. My 1Gbps line is working at 100Mbps. I've tried plugging directly onto the CPE - the lights keep flashing green (which I am led to believe indicates a Gbps connection) but the device plugged to the CPE always defaults/negotiates to 100Mbps.

My problem is a lot like this thread about Vumatel fiber box to router - no device plugged into the CPE achieves 1Gbps. The same devices and cables achieve to my router/switch achieve 1Gbps.

How can I prove to them their CPE is faulty? I have a MikroTik RB260GS which has a vacant SFP port. Which transceiver module could I buy to plug the LC connector directly into it? (i.e by the CPE altogether). (I don't know their Fiber wavelength).

All the cables involved are Cat6.

Well, realistically you only have to prove to your ISP that the CPE is faulty and they will need to fight Vumatel.

Vumatel won't listen to you, so if all the troubleshooting done via the ISP shows your line is 100 then they need to open a ticket with Vumatel.

If you have a Raycore CPE then the LED should be orange for 1 Gbps connection. A green LED is 100 Mbps. If your Gigabit capable router and also a directly connected computer with a Gigabit Ethernet adapter negotiates 100Mbps then I would suspect the cable. Have you tried more than one CAT6 or CAT 5E cable? If one of the pins on one of the plugs is not crimped properly then it may get 100Mbps speeds. Also if you connect your computer to your router with the same cable, does it negotiate Gigabit between the two?

I've sent them plenty of evidence. Like I say: 2 separate laptops and a desktop all with Gigabit NIC cards are unable to sync at 1Gbps when connected to the CPE. To my own routers, they do. At one point I found myself thinking electromagnetic interference in the Lan cables that I switched the power plug next to the CPE off.

Negative. I have this CPE.

PS: In the test devices I mentioned previously I omit this test (MacOS with an Adam Hub) also capable of 1Gbps, just not with the CPE :facepalm:

You definitely have tried 2 different ethernet cables?

What does a trace route look like? In the other thread your latency to CT was 95ms, 95ms is like from here to Dubai almost

Before we get there, allow me to show you my laptop NIC on my LAN: 1.PNG

I then plug it into the CPE using a brand new cable: 2.PNG

Don't take my word for it. A short (but big) video (Google may take a while to give you an on-the-fly play of this video)

Subsequent speed tests were below 5ms:


The traceroutes below were performed on the LAN only (i.e via my router) - not directly into the CPE.

I found my problem. Well, 2 problems.

i ) Ports 1 to 5 on the CPE are busted - they only negotiate to 100Mbps. Using CPE Port 6 to the same laptop used in the previous screenshots above works at 1Gbps.

ii) My Router WAN port is busted. It only works at 100Mbps irrespective of what's the upstream device is capable of. I am led to believe/suspect they got fried recently when my Cameras switch also stopped working. I replaced that with the MikroTik I made mention of in my previous post. Since the rest of the devices (CPE and Router) continued working, I didn't think they too might have been affected by the previous power surge (that I I was aware borked my TPLink switch). Since that surge though, I did procure a mini UPS to avoid loadshedding being a b****.

I am now using Port 6 on the CPE but I need a new router. For those who care, the CPE version pictured in my OP is a GSW-2020F. It previously gave someone here a problem. They are made by a company called Foranet or something (their website is Fubar).

My original post was asking for guidance which transceiver model would be appropriate to test my setup bypassing the CPE: mine is a 1310nm 1.25GB SFP module (don't ask me how I know).

FYI @PBCool - I am updating my support request with the same.

I picked up this Gigabit-capable MikroTik hAP Ac2 off Gumtree for half the retail price and I can confirm, my network is back to satisfactory.
