Odd TBB test ?

[#1]

@30FTTC06 i know i have a decent set up   router is the ASUS DSL AC68U , while 85% of tests are all perfect what is the cause of the spurious TBB test ?

it must be somewhere from BT network that PN has no control over

@rongtw I guess you just need to keep plodding on with it, here is another great tool legume posted london based.

nteperf this one is seriously responsive!

Don't know about iperf but you can do a similar test with netperf to a London server wg with 0.5s interims =

 netperf -D -0.5 -H flent-london.bufferbloat.net -t TCP_MAERTS -l 10

Here you go, I would expect delay to be shown there if you have any bad links etc.

[#9]

@ejs yes i have the PN one as a spare , this was the reason i got the ASUS 

[#10]

@Kelly Latest test, something has clearly settled down?

Still behaving itself?

[#12]

gateway pcn-ir01. is terrible   pages slow load buffering on iPlayer ETC  gaming is dire , and every time i drop connection

i get back on same

[#13]

eventually got off pcn-ir01     but now ,,,,,,,,,,Sorry, the tool failed to identify your gateway; 

core2-hu0-18-0-0.colindale.ukcore.bt.net (62.172.103.16) 5.727 ms   But test is  a lot better  Obviously a problem with the ir01 gateway

[#14]

rongtw: where are you getting PNC-IR01 from? The gateway checker? Or  traceroute?

(You're probably still using PCN-IR01, as it's a core router in Colindale)

[#15]

@Kelly  yes the gateway checker
