I can't seem to get DIR-655 to communicate with Motorola SB6121 cable modem. Don't know if it has anything to do with the old firmware 1.21?? Should I update the firmware? If so, which version?

View 1 Replies View RelatedRecently changed modems because of ongoing issues with Mediacom's loaner. I now have a Motorolla SB6121 and use an Airport Extreme router. I've used the Dell in the passed with the apple router, and several different modems and all was fine... but for some reason this hookup is not working for my Dell Studio. It sees the network, but will not connect to it. I did nothing different other than plug everything in. No other computer has an issue with this connection - only the Dell.
View 1 Replies View RelatedMy Motorola SB6121 DOCSIS 3 modem is connected to a Medialink n-band router. Sometime in the morning (usually between 7am and 9am, the router loses the ability to see the modem. I can access the router's control panel, and I see 0.0.0.0 for WAN IP, Subnet Mask, and Gateway. Primary and Secondary DNS server are both blank. Connection Mode is Dynamic IP.I lose the ability to access the modem's control panel directly (192.168.100.1), even though the PC I use is hardwired to the router. So, I unplug the modem, unplug the router, wait, plug in the modem, plug in the router, and everything works again.I've had more than twelve service calls. Every Charter tech looks at the line, puts in boosters, takes out boosters, replaces splitters, and seems to only look at signal. I've BEGGED Charter to let me speak to an engineer, because my suspicion is that it's something to do with the DHCP server.
I did, by the way, replace EVERYTHING.I have had 5 different modems...same problem. I have had 5 different routers...same problem, including a modem/router combo.I've tried different brands, too.I've disconnected all wifi devices from the router, and rebuilt my PC's operating system. I've even unplugged the refrigerator, because one Charter tech claimed it was "upstream noise."I've been online only a few times when the system actually goes down. What I notice in the router logs is this: [code] So at 9:34, no ranging response - T3 timeout, followed by Unicast Ranging Received Abort Response;
then the Cable Modem Reboot due to T4 timeout, and the system time goes to 1/1/1970 at midnight. No ToD.
The last piece of information: Charter installed a second modem as a "test." That was originally in the same room. A month ago they did another line from the box directly to the test modem to skip the splitter on the house.That modem shows the same problems, EXCEPT -- not perfectly in sync. I might see the same error, but the time will be a few minutes and seconds off. And sometimes I'll see the errors, but the modem won't go down.Sometimes the first modem goes down, sometimes the second. I'm accustomed to a router "healing" itself when the modem goes down.It might be off for a bit, but then will re-establish. This Medialink doesn't do that. It forces a physical restart every day. There are other outages too, and all I get from Charter is "the signal strength is good."
Swapping cable modem SB5101 that has been working for years for newer one SB6121. F5D8235-4 v2000 router has been working with SB5101 for years. When I connect using same cable/etc. Router cannot get DNS/IP from ISP (Comcast). Cable modem works directly connected to my laptop. Switched back to SB5101 and works again flawlessly. FW on router is 2.01.07. Had comcast tech support as well as comcast tech onsite- no resolution. I did activate new modem thru ISP (even with them here doing it).
View 8 Replies View RelatedI have a 192.168.1.xxx network connected to Verizon FIOS via Actiontec MOCA / router. I also have a 192.168.15.xxx network connected to Comcast via Motorola VT2442 router (used for Vonage) and a Motorola SB6121 cable modem.
Each network has it's own gigabit switch connected to each router. The two networks are physically separated but switches and routers are physically side by side.
What is the best configuration to allow devices on 192.168.1.xxx network to communicate with devices on the 192.168.15.xxx network (share printers, NAS, etc), but still have each network served by it's respective ISP, and each device still get it's dhcp, dns, gateway, etc from each respective router?
When I plug my desktop into my wireless router I have slow internet but when I plug directly into the modem I have no connection at all. It says "cannot connect to primary DNS server". I'm using a Motorola SURBOARD SB6121 and a NETGEAR WPN824V2 Wireless Router. When I do ipconig /all this is what I get:
View 11 Replies View Relatedwhen I connect my DIR-655 to the Motorola SB6141 cable modem I notice that the link speed LED on the cable modem never glows blue indicating a gigabit connection, it only glows amber indicating a lower negotiated speed. I am using a Cat6 cable between the two devices and have also tried a Cat5e cable.
When I try and force the WAN port speed to 1000Mpbs in the router interface the cable modem link speed will not light at all with no connectivity. Only resetting to Auto WAN port speed restores functionality albeit at the lower negotiated speed setting.
I'm running the DIR-655 rev B1 at 2.03NA firmware level.
I did connect the modem directly to my PC that uses an Intel Gigabit ethernet card and still had the lower connection indication (Amber) so it seems that the modem might be faulty.
I get this at random times. My internet disconnects until I reset my modem and I don't think it has anything to do with the modem because I had it replaced by my ISP and they did a few line tests and nothing was wrong. What can I do to avoid having this problem anymore? It's been doing it for almost 2 weeks now and when it decides to do it is random.

View 5 Replies View RelatedProblems have arisen since purchasing a new laptop with Windows 7. The problem seems erratic. The laptop connects to file servers on the network, but often cannot connect to the network. If it connects, often connection is lost when clicking to a new page.Usual error message: "Windows can't communicate with the device or resource (primary DNS server)"Network map shows communication lost between ADSL and network.Direct Hard wire connection to internet through ADSL works without issue. Hardwire connection through DIR-655 same as wireless: erratic, error messages.

Router setup numerous times using CD ROM set up program.Firmware updated to the most recent version.Gone to tech support several times; can get the PC to connect and once done, tech support says its working only to disconnect within a few minutes.What must I do to get this DIR-655 router working on a regular basis?
Any way to force the router to communicate wirelessly at only 1 or 2 Mbit/sec? I am having trouble connecting to another device, not made by Dlink, and their technical support suggested testing at a lower data rate.
View 1 Replies View RelatedI've been trying to connect my D-Link DIR-601 router with a Motorola SBG901 cable modem. The modem itself has a built-in WIFI (G) and one ethernet port, but not good enough for my purposes. I need more wired connections and an (N) WIFI connection, which the D-Link could provide, if I could get it to work. I just cannot get the two pieces of equipment to talk to each other. I can set up 2 independent LAN's, but no WAN (internet connection) from either. D-Link has provided pages of instrutions, but nothing works.

View 2 Replies View RelatedI have a Windows 7 computer with Comcast HSI. It's a very fast computer, but the modem was really outdated. So was the router. So, we got a brand new Cisco N+ Router and a Motorola SURFboard SB6121 modem with DOCSIS 3.0 and IPv6. However, when plugged in, the new modem will not consistenly connect to the internet. We called Comcast and they tried to send an activation code to the modem with it connected to the computer directly, but it was intermittently going online, then offline, then back online, then offline. We exchanged the modem for an identical one, but it's doing the same thing, so the modem can't be at fault here. Comcast tried to tell us that something was wrong with our coaxial cable, but our old modem - a Motorola SURFboard 4100 running DOCSIS 1.1 - was working just fine with the same cable. Another technological "improvement" has failed me.
View 7 Replies View RelatedSo I just noticed on my Cable modem the link light is blinking orange, per Motorola if its blinking orange - Computer is connected via a 10 mbps or 100 mbps Ethernet port.
On the Linksys E4200 status page it says
Internet Port Speed:
Internet 10/100 mbps
Local Port Speed Port 1 - 1Gbps
Maybe I just noticed this with this router, but I'm pretty sure this didn't start happening until I updated to 1.0.03.
Previously the link light was blue indicating a 1Gbps connection.
where is the WEP located on my att Motorola router?

View 2 Replies View RelatedMy friend and I bought Acer Aspire 5741's about 9 months ago and neither of us has had any problems until now. My friend went to connect to the internet via wireless router yesterday to find that there was limited connectivity (no internet access). We assumed it was a router issue and I gave her a number of things to check but all seemed ok with it. I went to her house to look at it today and when I ran the connection troubleshooter got "windows can't communicate with.......... (DNS server)". I connected my laptop via her router and everything was fine. I brought her laptop back to my house and tried to connect to the internet via my router and got exactly the same 'DNS' message - my laptop again connected without any problem.
I have re-booted the routers, laptops, network adapters etc and also checked the wireless adapter settings on both laptops, which appear to be the same. I have re-set the TCP/IP stack and have also tried ipconfig /release and /renew - none of which seems to have made any difference. the results of the tests are as follows (linksys is the SSID in use):

View 6 Replies View RelatedThe only way we can use our Motorola router is unencrypted. I have gone into the router numerous times and reset it, unplugged it, retyped the WEP key, tried to shift to WPA and nothing works. None of three computers in the house will connect unless all encryption is off. We live in a good neighborhood on a cul de sac, don't get a lot of traffic through here, and know the immediate neighbors, but nothing is stopping a stranger with a laptop from sitting on the street and using our wifi. I've talked to the Comcast tech. The trouble just seems to be our boxes won't get past the WEP encryption stage.
