Dell :: Motorola SB6121 - Unable To Get Wi-Fi?
Jun 23, 2013
Recently 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.

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?

My 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).

I 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:

My cable provider has installed a separate RCA DHG536 modem for my VoIP phone service alongside my SB5120 modem, and charges me $7 a month modem rental. I am upgrading the SB5120 to a DOC 3.0 modem and wonder if I can abandon the DHG536 modem?

I 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.

I have a laptop just configured with XP SP3 and the wifi works fine, except at the users house on a linksys router, hosted by comcast. The unit can not see the router right next to it and the wifi can see several other routers in the area. We tryed to use the microsoft install wifi driver with the same problem! My question is can the router be blocking my laptop out? Laptopis a G device and the router is an N device but works with another laptop in the house.
The difference could be the incription used laptop uses 128 and the router is set to 64?

I've bought a second hand Dell Mini 910 and when I tried to get online it kept saying to change the settings on Wireless Zero Configuration (WZC). I goggled it and checked the box in Network Connections. It allow Windows to configure my wireless network connections and I run Wireless Zero Configuration and selected Automatic. It will now pick up connections and allows me to connect but when I go into Internet Explorer still no joy so I've gone into Internet Options and LAN settings and clicked to Automatically detect settings but still no joy, I also have to do the above each blooming time I restart the net book. I've tried IE and Google Chrome and I've run diagnostics and they said to check with XP help etc.
1. Complete Internet Repair tool.
2. Fan bar.
3. Mini Toolbox.
4. Uploaded a folder from forum and dragged to system32 folder/
5. Searched for hidden file Ancillary Function Driver for Winsock to delete it but it wasn't there.
6. Entered a CMD prompt I was advised to do.
7. Set up a new user account and deleted the other user account and contents.
8. Downloaded and Run Winsock XP Fix
9. Downloaded Unknown Device Identifier
10. Re run Fan bar

Mid-day Thursday one of the laptops in my office suddenly was unable to identify the wireless network.
I have had this problem in the past with the other Dell laptop. Both are Windows 7. Tried uninstalling the adapter 4 times now. Changed SSIDs on my network. Added a SSID. Nothing works.
I am able to identify and get online if I put the IP address and DNS server in. Nothing I do lets it use DHCP.

i have 2 dell computers (and more but just worried about these two for now)... mainpc and sparepc, i had sparepc hooked to my tv and all pc's in the house, and a tv, networked to it... it all worked great, after a few minutes of setting it up... and then the hard drive crashed on spare pc and i got a new one, installed windows again both pc's use the same installation disk both pc's are hooked to a workswitch, which is hooked to a uverse gateway (router)... but it should be noted that hooking everything to wireless changes nothing... i get the same results can reach out to anything in the house and network great... but nothing can connect to sparepc... it keeps asking for username/password, even tho none is set I've gone through all the file sharing, homegroup, and folder options... ive reset ownership on folders and permissions... ive tried making/changing user profiles... but i cannot get from mainpc to sparepc home group does not work because the network does not work. as soon as the network works, homegroup will spring to life (at least, thats what happened the last time) if i right click on a folder, go to properties, share tab, and hit the share button... it asks for permissions for users... i set them, hit share, and it comes up and says, "you cant share this folder" ... with no explanation

I have a wireless network using an Apple Airport router. There is an iMac, an IBM Think Pad and a Dell XPS 410 tower (both running XP) on the network and all were working until this week. All of a sudden I can not get on the internet with the Dell PC. When I try to log into the router, it searches for a connection, but never is able to attain one. My network is displayed and I am using WPA security and have been entering the correct key. I have tried reinstalling the drivers, but with no success. I believe I was able to access a local unprotected site, but after being connected a pass word was required. I also tried ipconfig, but it just flashed on and then immediately off.

I am unable to connect to the internet in wireless mode. It shows the available networks, but does not connect when I type in my router password. I have tried everything I know of. Uninstalled/Reinstalled the driver - I have an Intel 5100 AGN wireless driver installed. I disabled and enabled it. Didn't work. Running command prompt and typing in ipconfig /all doesn't detect my adapter device.
I also did these by running command prompt as an administrator: [code] and restarted my computer. I have a Dell Studio 1555 with Win 7 (32-bit) Professional. I know this is a problem with my Windows as the wireless works seamlessly in my Ubuntu.

I have a Dell Vostro 3300 laptop with Windows 7 and ran a Kaspersky Virus Scan which deleted virus' and trojan programs but now my computer says there are 'no connections available'....my WiFi is definitely working as I am able to connect on my phone and other laptop.I have checked my network adapters on Device Manager and they have a yellow triangle with an exclamation mark, including 'DW1501 Wireless-N WLAN Half-Mini Card'. I have checked whether the drivers are up to date and it says they are.

I am now unable to access the internet with my Dell 560 running windows7. I have Verizon Fios for internet access. Windows network diagnostics reports that the connection between my access point,router or cable modem and the internet is broken and the network gateway is accessible but windows could not receive network traffic from the internet. Verizon's in-house -agent reports that there seems a connection problem between my router and the wall jack. I am able to access the internet with another computer and the the same router. I also have no problems with my iPad. I have interchanged cables and ports on the router.

I have a Dell 570 Inspiron desktop running win7 home premium w/ a 64 bit OS. I have Frontier dsl with a Westell 327W modem and a netgear router. Two desktops are connected to the internet...one through the modem and the Dell 570 through the router. I also run laptops through the router w/no problem. This morning the dsl went down, and when it came back up, the Dell 570 would not connect. i tried Diagnosing Connection Problems, and I'm told to turn off the modem/router (which I have done a gazillion times).When I look at Network Connections in the Control Panel, It tells me I have an unidentified network and can't connect. I read through some forums earlier, and found that releasing and renewing ipconfig often corrects the problem, and that's when I got the message that 'An error occurred while nenewing. Local Area Connection unable to contact DHCP server.' This set up has worked for the past year and a half. I looked at the network adapter, and it says it's working properly. I changed the cables going to the machines, and they both work on this computer. The only change made to the computer was to install McAfee security center through AOL yesterday, but the set up worked all yesterday and last night.

Now that the wireless on my Dell XPS 15 Z is fine, I've run into some problems with internet connectivity with Ethernet cable. Since the beginning, I wasn't able to connect to it through cable. When I connect my laptop with the cable, it says that it's connected, and that it has an internet connection. However, I can't get on it... My browsers don't have internet, and other programs can't connect either. (that while it says that it's connected to internet, quite strange)... I was thinking of some security adjustment that might block the internet connection or something, I don't know.
Oh, something that I should mention... I was able to get internet through Ethernet cable when there was a firewall... But when there's no security to the network... It isn't possible to have internet and it gives the situation described above. (any other laptop can connect with the network, so there must be some adjustment issue...)

I have a Inspiron 8000 and I just formatted the hard drive. I had been using a D-link wireless USB adapter with a D-Link wireless router - with no problems, but now when I try to reinstall the usb wireless adapter it asks for a hard wired connection to the router and even then it won't install and will not connect wirelessly or with the network cable. it seems the internal Dell network adapter has been affected in some way and will not work - as you can see I don't have alot of pc savy..?
