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.

cal

CAL(1)							    BSD General Commands Manual 						    CAL(1)

NAME

     cal -- displays a calendar

SYNOPSIS

     cal [-smjy13] [[month] year]

DESCRIPTION

     Cal displays a simple calendar.  If arguments are not specified, the current month is displayed.  The options are as follows:

     -1      Display single month output.  (This is the default.)

     -3      Display prev/current/next month output.

     -s      Display Sunday as the first day of the week.  (This is the default.)

     -m      Display Monday as the first day of the week.

     -j      Display Julian dates (days one-based, numbered from January 1).

     -y      Display a calendar for the current year.

     A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: ``cal 89'' will not display a calen-
     dar for 1989.  Two parameters denote the month (1 - 12) and year.	If no parameters are specified, the current month's calendar is displayed.

     A year starts on Jan 1.

     The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September.  By this time, most countries had recognized the ref-
     ormation (although a few did not recognize it until the early 1900's.)  Ten days following that date were eliminated by the reformation, so
     the calendar for that month is a bit unusual.

HISTORY

     A cal command appeared in Version 6 AT&T UNIX.

OTHER VERSIONS

     Several much more elaborate versions of this program exist, with support for colors, holidays, birthdays, reminders and appointments, etc.
     For example, try the cal from http://home.sprynet.com/~cbagwell/projects.html or GNU gcal.
