D-Link DIR-655 :: Not Linking Up With SB6120 Modem
Oct 21, 2011I called up the ISP and had him activate the Sb6120 modem.The Dir-655 will not link up with the Sb6120 unless I drop the WAN port speed down to 10MB. Then it will connect. (the light on the modem will come on). I thought the modem was bad so I had the ISP deactivate that one and we tried another Sb6120 samething.I did the firmware update on the Dir-655 to current but samething.
Firmware Version :1.35NA, 2010/11/12
Sb6120 Modem - Wired Is Always Going To Be Faster Than Wireless
Jan 6, 2012Just got cable and new hardware and been running bandwidth tests. I know wired is always going to be faster than wireless but was wondering if there were things I can do to see where the bottleneck is.
I have cable internet with a sb6120 modem and the asus rt-n56u router. When I go wired, I get 40+mbs down and when I go wireless I'm getting approx 20mbs down. Dont get me wrong, this is more than adequate but was wondering why the huge difference. I'm not anywhere close to the theoretical max.
The rt-n56u is on firmware 1.0.1.7f which is current. My desktop uses the WMP600n and my laptop has the Intel 5100 AGN built into it - both have updated firmwares.
Motorola Surfboard SB6120 Modem / Can't Get PC To Connect To Broadband
Jun 22, 2011I can't get my PC to connect to my broadband. I am running windows 7 64 bit and use the following:
Motorola Surfboard SB6120 modem;
NetGear WGR614 wireless router
I am able to connect with other devices (iPhone, Roku) to my wireless through the wireless router. My computer recognizes the broadband connection, but it won't connect to it. I get two errors when I try to connect:651: the modem has reported an error, and 638: the remote server is not responding in a timely fashion.I have tried connecting the ethernet cable directly to the modem, but I get the same results.Also, I have tried to cycle down the computer, router, then modem and turn them back on in reverse with no change in results.The connection worked until I clicked "disable connection" one day when I had trouble connecting (high traffic i think). Since then, the"home group" I set up originally with the connection wizard disappeared, and it had not been able to connect since then. When I try to connect I click on a small icon in the lower right that says, "not connected, connection available", then I click on the button to connect to broadband and get the errors described above.
Motorola SB6120 - Port 888 Redirect To Cable Modem?
Sep 18, 2011I was working with Motorola SB6120 cable modem regarding an odd power cycle issue (it would power cycle randomly for 24 hours). While trying to diag the issue, I was taking a peak in his router config and found a port set to forward as:
Application: Comcast
Port From: 888
Protocol: Both
IP: 192.168.100.1
Port To: 80
I understand that his modem admin page is now available from the internet. He said his friend set this up to "modem", but I don't see any advantage of having this done. At this point what are the other advantages of forwarding such ports?Another key note: When the port forwarding was disabled, suddenly the power cycle issues stopped.
SB6120 Looking For Best Possible Router
Dec 19, 2012My boss is been looking to expand his side business of trading online. He asked me to look into finding him the best and fast router possible that would give him the best speeds possible. He is currently using the asus black diamond router and the Motorola SB6120 modem but would like to know if there are better options, spending a few hundred on a router isnt a big deal. He also wants to know if there is anything else he can do with his pc, like network card or modem.

Oct 19, 2011So 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.
SB6120 / Surge Protector For Cable?
Dec 22, 20101. Our Motorola SB6120 popped out of existence today; FYI, this was plugged into a brand new APC UPS unit (which does not have coax/cable suppression features).
2. Previously (past days), one interesting thing I have noticed is excessive amounts of distasteful electrostatic shock when working in the closet and touching the metal bearings of the cable & wires. Is the cable not grounded properly, and is it the cause of #1?
Recommend me a surge protector/suppressor strictly for cable (do not need outlets/ethernet/rj45/etc).
Sb6120 Newly Built Desktop - Want Wifi
Aug 4, 2012I'm setting up Blast! Comcast/Xfinity internet (50mb/s) using an SB6120 modem and a linksys E3000 router. I haven't done anything yet, as i haven't received the modem in the mail yet, but i want to be prepared and knowledgeable when it all arrives. Here are my questions I've heard that running this router/modem setup on the N band at 5Ghz provides the best signal strength. How do i configure this? The main goal is to take advantage of as much of the 50mb/s as i can (i know this number is not practical due to overhead estimations etc).My newly built desktop has one free PCI-E slot (the other is occupied by my EVGA GTX 670) and 1 or 2 PCI slots. What's the best option to give my desktop wifi capabilities (pci card or usb adapter) in order to maximize signal strength? I'm about 10 feet away from the router, a door separates the computer from the router.

Feb 26, 2013I was trying to access the modem router as the admin but AT&T seems to have a pain in the butt security system from me making any changes. I wanted to forward some ports to setup my Synology DS212j Network Attached Storage (NAS). I connected my d-link router to the already setup modem router which I am now connected to. I have to run off to school but I was wondering, would I be able to forward the port off my d-link DIR-601 and be able to host my NAS server off that?
I don't have too much in-depth networking experience besides setting forwarding ports, setting static IPs, but I can't do that since I am not the admin for the AT&T router. I figure the password for the AT&T router is just defaulted to admin or blank but I haven't had time to fully test everything out.
New D-Link Modem / Router Connected But No Internet Access?
May 19, 2011My desktop recently broke so i bought my first laptop. I have AT&T DSL and i bought a new D-Link DSL-2640B modem/router so i could have wireless internet. I installed it and i was able to use it with the ethernet cable, however when i tried to use wifi, it worked for only about 2 minutes before it disconnected.. Now when i try again it says that it is connected (full 5 bars) but it also says there is no internet access and i cannot use the internet.
Also, before, with the old modem i was able to just connect the ethernet cable to the laptop and just start using the internet. Now i have to connect by putting in my username and password provided by my ISP almost like if it was dial up. I don't know why i have to do this now but not before.

Sudden Wireless Access On Belkin Modem / Router
Jul 28, 2012My Belkin "ADSL 2+ Model with Wireless G" router suddenly stopped allowing wireless access this afternoon - right in the middle of use - although the wired connections to that router still work fine. No settings seem to have been changed on the router, and I'm the only one with access. Two phones and a laptop that normally work fine just won't get an connection. The laptop - running windows 7 - says the configuration saved did not match what the router was asking for. I tried another computer that doesn't normally connect by wireless and was prompted for a WEP key - which is odd because the router is configured for WPA/WPA2 AES access with a 9 character pre-shared key. After trying a key unsucessfully I haven't been able to get that prompt up again.Meanwhile I've gone into the router settings and it's definitely set to ask for WPA/WPA2. There are some WEP keys specified if I use the drop-down menu to select WEP, but I can't get any device to prompt me to enter one now.

View 7 Replies View RelatedLinksys Wireless Router :: Internet Access From DSL Modem But Not From WRT54G
Dec 25, 2011I am trying to get wireless internet set up again and have run into a big issue. Previous wireless router was also a WRT54G and she had problems. I gave her my old one that I was no longer using, but it was still working with no problems.
The problem that I am having is that we are unable to get internet through the wireless router. We are able to get the desktop connected to the internet when we plug it directly into the DSL modem, but when we plug the wireless modem into the DSL modem and the desktop into the wireless modem, then we don't get any internet connection at all.
I had her do a factory reset on modem so that we were starting fresh. I have also tried unplugging both modems and then pluggin in the DSL and then Wireless modem, with no change. We have the ability to get into wireless settings page, but I'm not sure what in there to change that would make any difference on this one.
I know that this problem isn't actually a wireless problem, but it has to be related to the modem. We haven't even been able to get to the wireless part of the set up and we are already running into problems.

Jan 31, 2012My laptop died last week and have been using my husbands, which I hate! We had some issues with computer freezing on some webpages or after being on webpages for awhile (like facebook). Yesterday it froze and I could not get it back on. When he got home he did scan disk (which I also did) and got it working after going into safe mode and doing system restore. He said an update had gotten through and messed things up. Anyhow, after he was on it a few hours last night, we lost connection. I figured the crazy weather was the culprit but it has been off all day. Our router is working and connecting but the adapter is not. Also our home phone says there is no line. We have unplugged everything several times, checked to make sure everything is in the right spots, I have even reset the router and rebooted the adapter. I uninstalled and restalled the adapter also. It is now telling me that "the connection between your access point, router, or cable modem and the Internet is broken". The only lights I have on the adapter are power, battery, DS and now the US light is blinking. The online and link lights are not on.
