Ip Address changes D/L rate

[wrecker]

Hi I am totally confused as to why my Ip address should affect my D/L speed my current ip is. Mon 30/07/2018 07:50 1.76 Mbps 1.81 Mbps 0.29 Mbps 31.50.236.41 and changed to this on Friday of last week without any router reset. previously my ip address was Fri 27/07/2018 08:34 3.25 Mbps 3.42 Mbps 0.29 Mbps 31.50.236.92 BT and had been this for a month. The router a Billion 7800DXL has not been powered down for at least 60 days. Please can some technically savy person explain how this can happen and how to avoid a repeat. I should say that I use this router as trying to use a HH 3 , 4 or 5 produces a D/L of less than500kbit/s Stats Below Mode ADSL_G.dmt Traffic Type ATM Status Up Link Power State L0 Downstream Upstream Line Coding (Trellis) On On SNR Margin (dB) 16.1 23.0 Attenuation (dB) 41.0 27.0 Output Power (dBm) 16.3 11.9 Attainable Rate (Kbps) 3120 1056 Rate (Kbps) 2368 448 K (number of bytes in DMT frame) 75 15 R (number of check bytes in RS code word) 0 0 S (RS code word size in DMT frame) 0.50 0.50 D (interleaver depth) 1 1 Delay (msec) 0.13 0.25 INP (DMT symbol) 0.00 0.00 Super Frames 0 0 Super Frame Errors 113960 1657 RS Words 0 0 RS Correctable Errors 0 2 RS Uncorrectable Errors 0 0 HEC Errors 483660 1456 OCD Errors 0 0 LCD Errors 0 0 Total Cells 196141201 0 Data Cells 12338172 0 Bit Errors 0 0 Total ES 40128 0 Total SES 1026 0 Total UAS 999 156

you don't need to power down the router to change ip address only need router to drop internet connection and you will normally get a new ip address when router reconnects to internet

Thanks Yes I was aware of that, perhaps I did not express myself very well. However it does not address the issue of why the D/L speed appears to be Ip address dependent.

Yes it's easy really, but out of your control.

When you connect to the BT network the mux has to find you an available IP address from several available blocks of addresses. When the router/modem handshake takes place a series of test tones are used to determine linespeed and connection method. Because this action is totally dynamic it can connect you to any one of a series of RAS servers and indeed metro centres to get you connected ... the paths of which may vary somewhat in quality and speed. Even though balancing does take place constantly across the network, some nodes will always be busier than others, it's a massive network. And that is why there's always some inconsistency with connection sync rates. A healthy line should see better consistency, but it depends on your location and that of your nearest point of connection and traffic.

Many thanks for that explanation. It is frustrating as some Ip addresses will allow me to stream lowdef TV while others wont. My exchange is Selborne cabinet 2 and i am about 5km as the line runs from the cabinet
