|  [speed/latency] Westell 7500 Very Slow During Download-
Hi. Having serious download issues with my Westell 7500. Had it 2 weeks, already replaced it. every morning-works great, by 1-3pm speed slows considerably, basically unusable by dinner time. spent hours on with tech support. VZN even chkd my physical line and undid some loops(?) to the central station. nothing has helped. even the modem swapped failed to solve.
here are stats from modem/speedtest.
Transceiver Statistics
Transceiver Revision
A2pB020b3.d20h
Vendor ID Code
4D54
Line Mode
ADSL_G.dmt
Data Path
INTERLEAVED
Transceiver Information
Down Stream Path
Up Stream Path
DSL Speed (Kbits/Sec)
3264
864
Margin (dB)
6.2
11.0
Line Attenuation (dB)
32.0
23.0
Transmit Power (dBm)
19.7
11.9
speedtest.net shows
28kbps download/710kbps upload.
which is the opposite of what I need...
per the 192.168.1.1 view:
Speed(Down/Up)
3264 Kbps / 864 Kbps
bit of disconnect. neither my laptop nor 2 other computers are showing good speeds. so can't just be mine (tested all on wired and wireless, same results).
thanks.

| Check your filters, jacks, etc. Margins should be far higher given your Attenuation, and you should also be seeing full sync speeds (3360/864). Also, slow downs later in the day are indicitive of congested routers in your area. Running a Line Quality Test usually shows this. |

thanks! line tests have been done, but they always come back with--"it's your computer". how does VZN or I fix the congested router issue? |

WOW!!! A 6.2 downstream margin indicates that it's not only router issues, it's something on the phone line itself, either inside your house or in Verizon's outside wiring. To check, try wiring up your modem to the main NID (Network Interface Device), and re-run the transtat page on a laptop. The NID is a gray or black box, usually located by the side of your house. It'll have either the Verizon logo or a Bell Atlantic logo on it, if it's really old. So, hook up the modem to the test jack, after unplugging your inside wiring plug, and post your transceiver stats. If they are substantially better, it'll indicate an inside wiring problem.
Also, since you mention that this happens on a periodic basis, could you check the margin numbers at different times (i.e. when it is working well vs. when it's really slow in the afternoon)? If we see a pattern in the margin figures, it might be an issue with a faulty connection outside. Also, do you hear any static on the phone when these speed issues occur? If so, call the voice repair and tell them that the phone service is having static issues. Often, they'll be able to identify issues on the line that end up improving DSL performance as well.
Hope this helps,

great ideas and info. things are going well tonight (d/l at 3.4Mbps...). re-ran stats. identical numbers for the transceiver stats. I'll try the nid test next.
thanks and have a great holiday. |
