HH2 dropping the connection.

Ted_ntsx — Sun, 12 Dec 2021 07:04:39 GMT

Recently, my HH2 has been dropping the connection randomly every day or so.

I noticed that in the routers "Technical log" there are lots of multiple entries like this:

DoS(Port Scanning): IN=ppp1 OUT= MAC= src=204.93.154.210 DST=86.147.9.132 LEN=60 TOS=0x00 PREC=0x00 TTL=53 ID=53122 DF PROTO=TCP SPT=57194 DPT=10000 WINDOW=14600 RES=0x00 SYN URGP=0 MARK=0x8000000

What does this mean, and could this be the cause of the router dropping the connection?

Ted.

I assume you mean a SH2 and not an old HH2.

please can you post the stats from your router enter 192.168.1.254 in your browser then advanced settings then technical log information .

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

enter your phone number and post results remember to delete number https://www.broadbandchecker.btwholesale.com/#/ADSL

Someone may then be able to offer help/assistance/suggestions to your problem

@Ted_ntsx that log means your firewall is working and doing its job and wouldn't be related to your connection dropping out.

Thanks

Neil

Yes, I did mean Smart Hub 2 and not HH2, sorry.

17070 from a corded phone always gives a totally quiet line. I have FTTC and the speed is always good. 20mb up, and about 70mb down, which is about the maximum I would expect from my FTTC

The link you posted just goes to the Broadband Availablity checker ???

with the drops in connection it is good to see what your line expected range is compared to the actual speed shown in your stats from your stats the drops in connection do not yet seem to have caused the DLM to take action

from checker results you are obviously in the expected speed range. if your connection is dropping on a daily basis does it happen about same time or just random? any changes near hub recently light christmas tree lights or similar?

The connection dropping seems to be completly random. Different times of day or Night.
Some times it has dropped 2 or 3 times in a day, and some times it is stable for a few days in a row.

No changes to anything near the Hub.

Looks like if it does get worse I will have to contact BT, but I doubt that would do any good unless it gets really bad.
Thanks for your help.

Hi @Ted_ntsx and thanks for posting.

Sorry you're seeing a few drops. How are you connected? Is it wireless or cable?

Cheers

David
