Since I had two long term intermittent faults cleared from my home phone line the ADSL performance has been rock solid - speeds up to ~18 - 19 Mbps. SNR ~3 dB. And it just keeps going, day after day.
But recently I find I am having to manually restart my router (Technicolor TG582n) every few days as, while the DSL link and WiFi still seems solid, and logging on to the router does not indicate any loss of connection, the Internet connection seems to have ceased effective operation. Anyone else having this problem recently?
This could be a known issue with the TG582n called WANDownSpoofing .
This message from Bob Pullen (Plusnet guru) may help https://community.plus.net/t5/Broadband/198-18-1-x-address-problems/m-p/1374877#M309074 which says
IIRC, after the last FTTC firmware upgrade we pushed out, we did globally disable the WAN spoofing across the units we'd upgraded. Not all of these will have been successful though due to routers being offline at the time etc.
There will still be some units affected and for anyone impacted, I would suggest they carry out the previously discussed 'fix' of telnetting to the router and doing:: dns server config WANDownSpoofing=disabled : saveall
Whilst I can't be 100% sure, I remain somewhat doubtful that we'll see any firmware upgrades for this unit from here on in.
For a slightly more verbose help from https://community.plus.net/t5/Broadband/technicolor-tg582n-router-update/m-p/1297858#M301810
If you are both familiar with Telnet - which you may need to activate first - then you telnet into the TG582n as follows -
Open a cmd window and then type the following
when prompted for the username it's admin (all lower case) then the password which is the serial number beginning CP...
At the telnet prompt, type
dns server config WANDownSpoofing = disabled
dns server debug spoof clear
dns server debug spoof list
The last two dns commands are to clear and check the cache is clear of spoofed addresses.
If you aren't familiar with Telnet and need more advice, please ask.
Well it is worth the effect as it does seem to happen still with these devices even if it has been known for a few years.it will not do any harm anyway so at least you will be one step closer to the problem if it doesn't solve it.
