Already searched in forums... I got my motorola sbv5121e cable modem and only the DS light is stable. US is blinking forever. Tried disconnecting the power and reconnect but still cannot synchronize. I called the ISP and they told me from Monday. I appear connected on their part. Any suggestions? Thanks!
-
A blinking US (upstream) light and a steady DS (downstream) light indicates the modem is receiving signals, but having trouble sending 'em. My first guess would be a faulty cable somewhere... Double check the cable between the modem and the wall isn't damaged.
-
Thanks Covvar!!! I wouldn't hope someone would be familiar with this... My cable tv is working so I guess cables are alright since I already connected the cable which splits to the tv receiver, directly to the modem as well to test it. I hope I'm right... But as a second guess, tv is just receiving right? I checked them twice though and they seem pretty tight...
-
I'm not positive, but I think TV is only downstream. It should work even if upstream doesn't.
-
That's what I thought... Gladly I can still use my A-Dsl... Waiting for the weekend to end sucks!
-
the TV signal is much more accepting of various interfearance as well using completely different signals then your cable modem.
CHECK YOUR ROUTERS WAN TYPE
most DSl connections use pp0e
most cable uses DHCP.
-
Actually DS is blinking now and US is off. I'm not sure what is trying to do. Router s completely individual and is connected to the modem. I need to make modem working first. Well I'm waiting for support in the morning...

I run this test too...
TCP options string = 020405b4010303020402080a00080f0f00000000
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.
Default TCP Receive Window (RWIN) = 66608
RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)
Unscaled TCP Receive Window = 16652
In Windows 7, unless "TCP/IP Auto-Tuning" is disabled, only the Current TCP Window is displayed. Use the latest TCP Optimizer for tweaking.
RWIN is not fully optimized. The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
64240 (up to 2 Mbit lines, depending on latency. MSS * 44)
128480 (1-5 Mbit lines, depending on latency. MSS * 44 * 2)
256960 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2)
513920 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3)
1027840 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 2664 kbps (333 KBytes/s) @ 200ms
Your TCP Window limits you to: 1066 kbps (133 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 45 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
What does this mean?
edit: Technician came in today and we did some tests. Everything worked better luckily after he left... I'm not sure if they configured anything in the box downstairs... Now I'm getting some descent speed at 3,5-4 Mb/s from a good server (i.e. nvidia) and 400-480 K/s upload in torrents. Of course I'm seeding qhimm torrents (AH, raw.dll) forever.
