First of all, thank you for your answer.

Quote:
The gateway configuration sounds unusual to me but your ISP is in Mexico so perhaps it's different. Normally, your LAN devices would have the router configured as their gateway (not a node at your ISP). Can you please explain this further.
I confirm that my router is not my gateway, it mainly acts like a DHCP device for my LAN, DMZ management, port-forwarding/triggering.
Here is the main information available on my Huawei router status page in the WAN section :

Internet:
IP address/Subnet Mask : 187.xxx.xxx.126/255.255.255.128
IP acquisition mode : DHCP
VLAN/Priority : 400/0
Gateway : 187.xxx.xxx.1
DNS servers : 200.38.100.210 207.83.200.200

IPTV:
IP address/Subnet Mask : 10.xxx.xxx.231/255.255.224.0
IP acquisition mode : DHCP
VLAN/Priority : 402/5
Gateway : 10.xxx.xxx.1
DNS servers : 10.0.1.130 10.0.1.98

Bridge :
VLAN/Priority : 401/7

Also, are you sure that, when your ISP brought new services online (Netflix) that they didn't alter IP addresses?
My public IP address didn't change when they brought new services online. I don't know if they alter the routes in my Internet VLAN nor in my IPTV VLAN.

Does your Huawei HG8245H have standard firmware on it or an ISP provided firmware to lock it down? If you can access it normally then you probably have a 'ping' diagnostic page within its menus which I would use when trouble is experienced to test the internet connection at that time. Are you using IP addresses in ping tests or URL's? If URL's then DNS could be an issue if the ISP has changed that.
The device information page says it is Customized for Totalplay, Mexico, and I have some sections that I cannot change, such as WAN/VLAN configuration, DNS servers, DoS Configuration (only ICMP redirection attack is checked), ALG configuration, and IGMP configuration.
I have access to a Maintenance page that allows me to make ping and traceroute tests. I tested using domain name google.com and gateway IP address. When Internet connection drops, both domain names and IP tests fail, and the router LEDs stay normal as if the link was still established.

Quote:
Your Huawei HG8245H should show you what gateway and DNS servers your ISP is expecting you to use. Is the Huawei HG8245H configured to pass these through (to LAN) or are these hard-configured on the LAN side (and now different to what the ISP is expecting)?
By default, the router passes the DNS and gateway configuration throught DHCP. I keep having this discontinuity of service even when I specify static DNS such as 8.8.8.8 and 8.8.4.4 on all the computers of the LAN.

Quote:
You ask for opinion. Well I would suspect that the problem is on the ISP side but it's possible that they've changed something which you've not picked up on.
Thank you very much for your help and opinion. I think that my ISP is hiding something. I am going to contact them again and let you know the outcome. Thanks again.

VLAN(7) 						 Miscellaneous Information Manual						   VLAN(7)

NAME

       VLAN - virtual local area network

DESCRIPTION

       This manpage provides a brief overview of VLAN (virtual LAN) technology.

       VLANs  are logical, or network segments that can span multiple physical network segments.  A primary benefit of VLANs is that they can iso-
       late broadcast and multicast traffic by determining which destinations should receive that traffic, thereby making better use of switch and
       end-station resources.

       Logical	separation  using  VLAN allows for the logical grouping of PCs, servers and other network resources to behave as if they were con-
       nected to the same, physical segment, even if they are not.

       HP-UX VLAN is an implementation of IEEE 802.1p/Q standards.

       VLAN interfaces can be configured in HP-UX servers using the command (see nwmgr_vlan(1M)) or (see lanadmin_vlan(1M)).  HP  recommends  that
       you  use  for  HP-UX Release 11i Version 3 and forward.	Interfaces can also be configured using the web-based management tool HP-UX System
       Management Homepage (HP SMH).

       Each VLAN interface created is assigned a VLAN PPA (VPPA) that is unique across the system and a VLAN ID, that identifies the  virtual  LAN
       it is part of.  The VLAN ID is unique on the interface on which the VLAN interface is created.

WARNINGS

       The  and  commands are deprecated.  These commands will be removed in a future HP-UX release.  HP recommends the use of replacement command
       nwmgr(1M) to perform all network interface-related tasks.
