Yea it does seem stuck as latency and upload is starting to get back to normal ill give it a few more days

Thanks

In reference to www.cisco.com/en/US/products/hw/wireless/ps469/products_tech_note09...:

Clear Channel Assessment Parameter (CCA)

CCA is essentially the establishment of a noise floor below which it ignores RF inputs, in search of a good, solid signal. With the programmable CCA feature, wireless bridges can be configured to a particular background interference level found in a specific environment, for reduced overhead contention with other wireless systems.

A CCA threshold can decrease the receiver sensitivity by changing the absolute receive power level above which the channel is normally considered busy. The default value of the CCA parameter is 75. However, you can increase the CCA threshold to reduce noise in environments. CCA values can be set independently for root and non-root bridges.

There might be intermittent connectivity loses with wireless bridges if the CCA value is not configured correctly. Ensure that the CCA value is not set to zero and is set to the value close to the default value of 75 if not the default value. Wireless bridges that run Cisco IOS® Software Releases earlier than 12.3(2)JA hit a bug which changes the default CCA value to zero upon reboot of the device. Refer to Cisco bug ID CSCed46039 (registered customers only) for more information on this bug and the workaround.

In reply to a post by Bapteeed:

Its been 6 days and some hours since the line issue was repaired , after 4 days latency dropped by around 15 ms

So i thought today i will restart modem and router

It often takes a couple of weeks for DLM to start to give you back a decent speed. After that, it goes up incrementally (band by band???) every couple of days or so till it gets to where it should be. So wait another week or so and hope for the best.

You shouldn't need to restart the modem. DLM will force a resync when it decides the time is right; often around 2:00am. You often do need to disconnect/reconnect or restart the router, to make sure that the BRAS/IP profile matches the sync that DLM has given you. It is worth doing this first thing every morning while hoping for a DLM change.

(The BRAS/IP profile is updated to match the sync speed every time a new pppoe session is forced; eg when the router reconnects to the exchange. Sometimes DLM reconnecting the cabinet<->modem connection kills the old pppoe session and there is no need for manual intervention on the router; but often the DLM reconnect is fast enough the router does not notice and keeps the old pppoe connection.)

Thanks Stephen
It did the fast reconnect when the latency decreased which also increased upload just seemed strange to lower the download speed

My profile resets a fair amount due to an electric key
Seems to reset to fastpath after a few days of uptime and increases sync rates

It has taken the DLM 20 days to finaly get back to original speed and latency

Restarting the modem or router has no effect on it apart from maybe delay the process
