The other day one of my offspring phoned me, being concerned about oddities experienced recently. One was that usage had apparently increased substantially, and that increase was analysed to be gaming and P2P, which neither he or his partner took part in. I believe the only hardware is the XP desktop and a laptop. Some IPlayer streaming is done as well. From our conversation I think wifi security is WPA2.

Therefore I cannot see how his connection could have been hijacked, though perhaps one of you may have some ideas.

He had also suffered great slowdowns in throughput, to a crawl, the disconnect with difficulty in recovery.

Below are stats sent me from the TG 585 v7(?)


Uptime:   0 days, 16:33:51

     00:01:22 (since last boot)   GRP Default destination is routed via gateway 80.229.119.154


      

 
     00:00:03 (since last boot)   [CWMP: 0:00:02.800] setting cwmp defaults
 
 
     00:00:02 (since last boot)   KERNEL Warm restart

The router summary upstream FEC and CRC errors, I think, could be evidence of the router having a start up wobbly, but all else seems, again to me that is, OK.

In the router’s event log I see nothing with which I am not familiar, bar the items listed. What CWMP and GRP entries are about, I have no idea.

Might the router be on the blink, or what?

Is the ISP (CP) PlusNet, by any chance?

The IP address quoted above resolves to PlusNet and the reference to CWMP make me think that PN were making remote modifications to the modem/router's configuration. 

The numbers reported for upstream FEC & CRC errors are clearly just the maximum value that those variables can store.

I prescribe powering off and disconnecting the modem/router from the telephone line overnight, thus allowing the CPE and the DSLAM/MSAN port time to 'relax'.

[renluop]

Oui, da, ja, ita vero!

I presume soft disconnect first before power down.

[burakkucat]

Yes, just follow the routine procedure. 

[renluop]

Thanks! But am puzzled why PN should be making remote changes to the router's config now to a legacy router.

How usual are upstream errors of those types? My CRCs over 6 days show as 615(~10 a day); his are incredible unless they are accumulated over a much longer period than 16.5 hours, or are a fiction.

[c6em]

The upstream will be B**cks

I expect the number shown will be 2 to the power something
and is probably the max number possible in x bit numbers stored in the router.

[burakkucat]

It looks suspiciously like (4 x 2³⁰) - 59 . . . or something close to that.

[renluop]

Actually a smidgen short of 2^32, courtesy my abacus!

[burakkucat]

2³² - 58 perhaps? 

[renluop]

9/10 actually 59.

[burakkucat]

   The embarrassed b*cat goes to hide.
