Router problem or ISP problem ?

Hi everyone,

I am experiencing discontinuity of Internet service, this started 1 month ago. Everything worked very well for 1 year of intensive use, but now, I have problems reaching my gateway.
The gateway is not my router but a node belonging to my ISP and I share the same public IP with other clients (NAT is moderated).

Problem : the connection keeps dropping every 4 to 10 minutes. During the cuts, the lights on the router do not change or do not display any failure/error, but every ping, traceroute and nslookup fail outside of my LAN and the connection drops from 50sec to 13min and 16sec, then comes back to normal with normal lattency.

My router is a Huawei HG8245H and its status page shows that the device is working normally even though I have from 6% to 48% of packet loss on extended ping tests to google (in general for 20 minutes tests - 1200 ping requests) on eth0 as well as wlan0.
My latest test was conducted during 24 hours : 85947 packets transmitted, 60065 received, 30% packet loss, time 86091921ms

Router's factory settings :
Open TCP ports are 22(SSH), 23(telnet), 53(domain) and 80(http) plus 2 unusual TCP ports 49152 and 49153 that cannot be closed (bug or additional maintenance ports ?)

The TV box connected to the router is working 100% of the time (even when my Internet connection stops working).
Internet and ipTV belong to different vlans and use different routes. (the TV vlan has a different gateway)
Detail : Sometimes, the sound stops during comercials, I can hear a dialer sound from the TV speakers, then the sound comes back after 5 seconds. The TV box is connected to the router through an Ethernet cable.

I sent all the screenshots and info to my ISP but they closed 3 support tickets (in a row) because they say they can't find any problem ... and they never let me know when they close a support ticket.

Would you be kind enough to give me your opinion about this problem, please ?
- Could it be a Huawei HG8245H router issue ?
- Could it be a damaged fiber issue ?
- Could it be an overloaded ISP node ? (unable to answer/relay the requests of all the clients ?)
- Could it be a bandwidth limit problem on one of my ISP nodes ? (this problem started 1 month ago and, aproximately at the same time, my ISP included Netflix in its triple-play package - coincidence ? - I suppose they had to garantee a minimum bandwidth allocated to each client in the contract, which would reduce the bandwidth limit available for Internet purpose)

The ISP is TotalPlay, in Mexico.

Thank you by advance.
Kind regards

Time::JulianDay(3)					User Contributed Perl Documentation					Time::JulianDay(3)

NAME

       Time::JulianDay -- Julian calendar manipulations

SYNOPSIS

	       use Time::JulianDay

	       $jd = julian_day($year, $month_1_to_12, $day)
	       $jd = local_julian_day($seconds_since_1970);
	       $jd = gm_julian_day($seconds_since_1970);
	       ($year, $month_1_to_12, $day) = inverse_julian_day($jd)
	       $dow = day_of_week($jd)

	       print (Sun,Mon,Tue,Wed,Thu,Fri,Sat)[$dow];

	       $seconds_since_jan_1_1970 = jd_secondslocal($jd, $hour, $min, $sec)
	       $seconds_since_jan_1_1970 = jd_secondsgm($jd, $hour, $min, $sec)
	       $seconds_since_jan_1_1970 = jd_timelocal($sec,$min,$hours,$mday,$month_0_to_11,$year)
	       $seconds_since_jan_1_1970 = jd_timegm($sec,$min,$hours,$mday,$month_0_to_11,$year)

DESCRIPTION

       JulianDay is a package that manipulates dates as number of days since some time a long time ago.  It's easy to add and subtract time using
       julian days...

       The day_of_week returned by day_of_week() is 0 for Sunday, and 6 for Saturday and everything else is in between.

ERRATA

       Time::JulianDay is not a correct implementation.  There are two problems.  The first problem is that Time::JulianDay only works with
       integers.  Julian Day can be fractional to represent time within a day.	If you call inverse_julian_day() with a non-integer time, it will
       often give you an incorrect result.

       The second problem is that Julian Days start at noon rather than midnight.  The julian_day() function returns results that are too large by
       0.5.

       What to do about these problems is currently open for debate.  I'm tempted to leave the current functions alone and add a second set with
       more accurate behavior.

       There is another implementation in Astro::Time that may be more accurate.
