TOT supplied ZTE F620 Lan Ports

[longball53098]

I have had TOT Fiber 2U for more than 3 years now. The F620 is the supplied ONU for converting the fiber signal to a home system. The F620 has 4 LAN ports for distribution to PCs and routers as needed. The box has done it job now for years and no real complaints.

The TOT speed package I have had all this time was a 990 baht pack that was 150 Mbps download. About a month or so ago I changed to a newly advertised pack that said 400 Mbps up and down for 750 baht so I jumped on this new promo. Nothing required except an order signed by account holder (my wife). They said a day or two to see the change of speed. 

I have 2 PCs cabled to two of the 4 ports and one WI-Fi router cabled to another port. A few days later I started doing speed tests o of the hard wired PCs to see a increase of speeds. Both PCs tested to servers in Thailand at about 104 Mbps up and down consistently. This speed stayed this way now for a month or more as I was trying to understand what was happening and figure out what I could do to fix it. The cable were connected WIFI router port 1, PC 1 to port 2, PC 2 to port 3.

First thing I did was look up the specs for the ONU. ZTE specs show this model of ONU has 4 LAN ports with the following specs for the ports:

Uplink interface SC/APC
User interface         4 10/100/1000 GE
                       2 Phone interfaces 
                       1 Power interface

This spec shows all 4 ports are capable of up to 1 gigabit ethernet speed. I kept getting the 104 speeds for the next month even after several resets of the ONU. Recently I had a friend next door with a same TOT system upgrade. He had the same issues and called out TOT. They found his PC cable connected to his WIFI router and not the ONU so they moved it to Port 1 of the ONU reset the system and magic he got the full speed of 400 up and down. He called me and said check my cables whick I alread knew were connected to my ONU. But just for grins I moved the PC to Port 1 and the WIFI router to port 3 and reset the system. Magic I now get the 400/400 on the PC. So I checked the PC on Port 2? Nope same 100 speed as before,,,,,,,,,swapping Pcs port 1 and port 2 allows the PC connected to Port 1 to get the high speed but anything connected to Ports 2, 3 o4 4 remain at the lower 100 Mbps speeds,

My conclusion is the ZTE Onu is not working as their spec says and my neighbor's does the same thing. We can only get the gigabit speed on Port 1 of this ONU. I intend to have TOT out here to explain this.

 

So why the posting here?  

 

Can anyone out there who has a system with the TOT supplied F620 confirm or contribute to this? Is the F620 I have faulty or did ZTE lie about the ports? Does TOT know about this? I can't wait to hear a TOT explain this issue. I want a ONU with 4 ports that work properly and as advertised.

I had the ZTE F620 as in the attached picture as there are several different ZTE F620 modem/ routers. I also have the 400/400 mbps package and I had around 400 mbps on all 4 LAN ports. My configuration is LAN1 desktop, LAN2 wireless AC1200 router (living room) and sometimes LAN3 laptop computer.

However, two weeks ago TOT gave me without any particular reason the ZTE modem/ wireless router as shown in the attachment. Will tell you the type later today.

Just tell TOT your router is not working and they will give you 

a new one, I did that a couple of months ago,because it did

not have WiFi ,maybe the same one you have now.on that

one only one port is Gigabyte, giving 1000 Mbps,

Thanks guys for the feedback

 

My issues solved as of yesterday morning. TOT was called out and came with a couple techs. After a brief discussion with me about my needs for at least 4 LAN ports capable of gigabit speeds the tech got a new ONU from his truck and installed it in place of the older one. So, the older F620 is now replaced with a F612. The new one only has 2 LAN ports but both gigabit capable. When I said I needs at least 4 LAN ports and my WIFI router is a personal router and older and does not support gigabit speeds he again went out to the truck and came back with a D Link WIFI router brand new in a box. Installed that and now I have a working system with new ONU and WIFI router and I have total 6 LAN ports gigabit capable.

So with the 3 PCs that are direct cabled to the router I get the full speeds my package is 400/400 down/up within Thailand. My speeds out to the world vary so we all know what that can be. Some countries good and some not.

So a simple call to TOT here in Ban Chang and a less than an hour I had my system upgraded for free. Not bad service as far as I can see,,,,,,,,,,,,,,,
