Not able to get a signal

I have had my Sirius Sportster operate without any problems for nearly 4 years. Recently I began having recurring problems either getting any type of signal, or having 4 "bars" show on the lower portion of my screen, yet still get the "awaiting signal" message. I have purchased and tried a new antenna, but this has not helped.

Slower wireless speeds

Sorry to see you leave FiOS.

Without knowing how your EOC-2611s connect to your network, I can only speculate. But...assuming your 2611 plugs into the Comcast router... Check the Ethernet port status. It should be 100Mbps Full (Duplex). If it auto-negotiated to half duplex, that would explain your throughput issues.

Shuts off...restarts, then runs for a few mins

If the modem is 10 years old then its time to replace it even if it was working fine if not very good to be abreast with the latest technology. The ISP must have tested the lines which must be fine because they keep on upgrading so you need to replace the modem to a latest model.

Telephone company installed Comtrend CT-301 modem. Recently having connection issues with computer and noticed RED alert light coming on frequently on modem. What is causing these problems?

I've seen bulging capacitors inside this modem causing me problems. Changed the caps and everything was OK for a couple of years after that. Started to have more problems with this modem recently, called phone company and sent me an new modem. Problem solved.
Also, it seems this old modem does not like the newer routers (D-Link DIR-615). It connected for a while, (30 seconds) then lost connection completely until power was cycled on model. The modem worked OK with older D-Link Router.

I have been with Comcast for 6 years. Leasing their SB5120 modem for 3-4 years, no problem. Then bought one myself and no problem for 2 years with Negtar wireless router. For the past few days, it started...

generally a wireing issue or signal issue i assume by this time you have it fixed by the date. you can check in a web browser and it should show the signals. if recieve is flashing then the downstream is either out of range or something else. it wont go to upstream until it locks onto downstream first.

Blinking light on Westell 6100 DSL modem

Blinking light means that firmware on your DSL modem just got updated. The modem is pinging the Networ/Computer connected to it. If you open your Modem Page you will see the difference, unless you never have done it before.

Dsl sync


The question I have is,
1. Did you have sync previously and it has suddenly stopped working?
2. Is this new a new DSL activation of service to your address and has not achieved sync yet?

for 1.
The most common issue is usually a recent change within the telephone environment or equipment at your address, does any of the following fit your scenario: You recently moved your DSL equipment to another room, you have bought a new phone, answer machine, Fax machine, Sky television subscription, a monitored security alarm service has been installed at your address or health monitoring equipment has been installed or an unlikely, lightening strike or power outage has occurred around the same time as sync was lost.
Any of the previous changes may have altered the way DSL signal is being filtered or split from your standard home phone signal, all telephone line using devices except for the modem/router will need to have its own DSL filter, if security or health monitoring was installed you will need to contact your internet provider and request a line splitter installation (this can be at some cost to the user, so don't forget to check what a local electrician can do this same job for)
DSL Filters can also be very susceptible to problems after power surge/failure or lightening strike at your address. Or if you have recently moved your DSL equipment, please double check the way you have setup the filter and cables at its new location.
The only test required to verify the issue is not at your address is known as an ISOLATION TEST. The router must be checked in a Phone signal free environment, please remove all phone cables from all jack-points within your premis and plug in only your router, without a filter, you should also test your router across all the jackpoints at your address if the first phone-jack you try fails) If we got lucky, you now have sync and the problem lies with one of your phone line using devices or the filter that it is using, start plugging each device back into the phone circuit one device at a time, with a filter and check to see if the router has lost sync after each device is plugged back in until you are able to identify the problem device, filter or jack-point.

for 2.
Follow the directions exactly as above and if no problem devices, filters or jack-points are found, then ISOLATE your router again and call your ISP provider and request firstly a "port reset" for your DSL port, this should be achieved within a 24Hr period, some are able to do this within 20min of your call, if sync will still not come up it is time for the ISP or service provider to send out a technician to verify the issue is not at the port, cabinet or exchange, this may take some providers up to 5 days to achieve.

Some last thoughts,
Dont rule out the possibilty of the Phone cable used for the router has failed (test the cable on a working home phone to verify it is still working)
or you may have bought an extension cable for your router, the length of Ph cable between your router and the jack-point can be no longer than 5meters before DSL signal fade can start to occur, the router will work at its best with a 15cm-30cm Phone cable, the 1meter cable usually supplied is fine.
Also, do check the jackpoints that you are NOT using at this premis (rare occasions have found me resolving sync issues because the vaccum cleaner has taken out one of your unused jack-points under the bed, in the spare room or the neighbours visiting toddler has tried to plug in a jam sandwhich or even a small plastic toy of some sort into an unused jackpoint)
If you are able, do check that your router can get sync and connect Ok at an address where DSL signal and Sync is currently known to be working.
If you have just moved to this address and your property is over 40-50Yrs old, you may want to check with the phone line provider to see if "line insulators" have ever been installed previously to resolve line noise issues, ageing line insulators will corrupt your DSL signal especially on the high humidity days.
I realise this must seem quite broad and intensive, this testing is intended to rule out any possibility of the issue being internal to your address (as we all know TELCO technicians are all too eager to hit you with unexpected maintenance charges if the issue is found to be internal to your property, as opposed to external)

Hope this gets you closer to identifying the source of your DSL sync issues, if you are like the many DSL subscribers out there, you cant stand to be without your high speed internet for more than two minutes either.

Happy hunting.

D link modem

try to upgrade the latest firmware for the router and that would fix this problem, check if this problem is with both wired and wireless computers, if not with the wired..only wireless has problems, check if you have any other wireless device operating in the same frequency of the router..if s, turn off other devices and check b.cos that me interfere your w/ls connection, if wired is having the same problem, connect modem straight to the pc and observe the connection, so that you can isolate problem.. Your router is not synchronized with the line. You should power cycle your router (i.e)disconnect power cable from the router waith for 30 seconds and then reconnect, check if the dsl cable is connected properly to the router, if yes remove it once and the reconnect it, this should fix the problem. upgrade the latest firmware version for your router .Are there any electrical devices near the router that are only switched on at that time of day and then switched off again in the morning. What i'm thinking is that you are experiencing REI or Repetitive Electronic Interference. This is caused by EMP emmisions form devices nearby. Have you had anything fitted recently that may be hardwired into you master socket, this will bypass your filter and cause interference on the line. The only other thing I can think of is that there maybe some engineering works going on at the exchange or on the line.
