Ever since changing ISPs, I have been using their new router, a TG582N.
Within a few weeks I noticed that it was reporting 3600 CRCs per minute. This was over a period of several days, but by re-booting the router, it stopped and reported a normal one CRC per 100 seconds or so.
The only reason I noticed this was that general browsing speeds were sluggish. I did a few speed tests and throughput was around 800k, previously around 4000k. This on a connection speed of around 5200k
Over a period of several weeks, the situation is this :-
If I run this router in ADSL2+ mode, after a few hours, it starts producing exactly 3600 CRCs per minute, which goes on forever, or until I re-boot the router. If it were a 'real' line problem, then it wouldn't stop when the router re-booted, nor would it be consistently 3600 per minute.
When I reported this to my ISP, they supplied a replacement TG582N router - This does exactly the same.
If I run these routers in ADSL2 mode, then there are no CRCs produced.
The ISP has increased the SNRM to 9.0 from 6.0 to see if that was the problem - It still produced 3600 CRCs per minute on an increased margin.
I have three other routers - A TG585v6, a TG585v8 and a DSL-2640B - None of these produce CRC errors in ADSL2+ mode.
I am currently running the DSL-2640B router on an SNRM of 3.0 and over a period of 76 hours, the router has produced 5790 CRC errors (One per 47 seconds) - Not brilliant, but the SNRM is always between 1.1 and 2.8. The connection speed is up to 5600k as well due to the low SNRM.
My question is this - Why is it that the TG582N router produces a consistent 3600 CRCs per minute when in ADSL2+ mode and no other router on the same line does, nor does this router do it in ADSL2 mode?
I have reported all of this to my ISP and their last statement was ''you have clearly shown, is an issue with the Technicolor router when running as ADSL2+.'' They also suggested upgrading the router to the latest firmware, but it is already on it.
They also said, ''Unfortunately we do not have a direct route of support with Technicolor''
Anyone got any suggestions?
