Xbox live lagging

After upgrading to this modem Mot SB6121) from a linksys DOCSIS 2 modem, my son immediately noticed some lags while play COD modern warfare 3. Character seems to freeze for a couple of seconds and then jumps ahead to resume play. Other players can see my son's character freeze then jump to new location.gameplay was fine with the old linksys. Speedtest is great with 17 mbps down and 3.8 mbps up with Comcast cable, and computer internet activity is just fine. The xbox console is connected via ethernet hard wire and the xbox connection test indicates the connection is fine. any ideas?

SOURCE: cable modem + dlink router

Your modem needs to be rebooted in order for your router to pull an IP from the modem. To do this, look for a little hole in the back of your modem and use a pen to push the button. Wait for the reboot to finish and then try again in about 20 seconds.

SOURCE: wireless routers

Just plug the cable modem ethernet into the input to your router and you will be fine. Just remember, if you decide you want to make any changes to your router settings through your browser, make sure you hook up an ethernet line from your laptop to the router before making any changes. The reason for this is if you make a change in security settings on your router while wireless, the router will reboot and if your laptop did have the settings changed in it, you can be locked out.
Not that you can't get back in, but it is a pain to have to do.

SOURCE: Unable to set up wireless router

Shut down your computer, unplug the cable modem and the switch. Connect all three - computer to switch, switch to modem. Make sure that the ethernet cable between the router and the modem is in the router uplink port and that the computer is plugged into one of the four ports that look alike. Wait 30 seconds - plug in the modem. Wait another 30 seconds, plug in the router, wait another 30 seconds and boot the computer. Open a browser and see if you have internet access. If you still don't, then try to check the browser by typing 192.168.1.1 into the address bar of the browser. That should give you the browser sign in screen. The Linksys default is to leave the user name blank and type admin for the password. That should give you access to the router so you can check the settings. If this doesn't work, document carefully what happens and post again with your results and we'll try to go from there.

Why dose my profile keep signing me out when putting on games and when trying to play some games


Sometimes it may depend on the connectivity of the level your internet. A while ago I had a lot of problems with internet and like you, my games often crashed.

The easiest thing is to check your connection and make sure you are getting a strong signal.

On Xbox 360 to check your connection just follow this link:

Troubleshoot Xbox 360 connection to Xbox Live

While it's a lot to read it will help you in the long run.

To check your speed on Xbox Live go here
Slow experience on Xbox Live (for Xbox One)

You can also check out to see if Xbox Live may be the problem. By going to this link.
Xbox Live Status

The next thing, try replacing your router, when I bought my new router my problems stopped. You can also upgrade to a newer modem to DOCSIS 3.0. This of course depends on your internet speed. If you are below 20mbs I wouldn't worry about upgrading just yet. But upgrading never hurts. However, if you are trying to get 50mbs or more DOCSIS 2.0 bottlenecks. While I am no expert on modems. I think the DOCSIS 2.0 modem bottlenecks around 38mbs.

To Check your speed on the internet, this is the site most people go to.

Speedtest net by Ookla The Global Broadband Speed Test

Use whichever server you wish. I usually do multiple ones to see how it differs.

Xbox live lag


This could happen for many reasons. It could be other people using up all you internet. If possible connect your xbox directly to your router or modem and see if that fixes the problem. If not use speedtest.net and see if the speed you are getting is what you are paying for.

I have frontier services with a net gear modem/router i was told by xbox live to get a d-link router an it would help my problem with running 2 xbox 360 with no lag whats so ever but dont know what im...


well, unless the D-link is also a modem/router, I don't see how ADDING the D-link router to a lagging network will reduce said lag. They probably wanted you to REPLACE the current router with that one.....

will "frontier service" allow that router to be set in a "modem-only" setting ? You'll have to get with them on that. as for the D-link, there are manuals as well as an Online Emulator that simulates the Router interface so you can see how to set it up....BEFORE you set it up !

[PS: tracking-down lag problems can be tricky....you should be experiencing bad lag with all sites for it to be your hardware....

When i play my xbox 360 im getting a lag...my friend said i should have a setting to prevent this but im not sure which one it is or how to do it..


Everyone experiences lag from time to time. Lag is often the Xbox (Microsoft) servers themselves, however if you are always the lag source, then there are several potential issues and/or solutions:

1) Open/Closed NAT (Network Address Translation): Your NAT should be set to open or not restricted. This is not a console setting. You must log into your router to change this setting. Typically this will fix your issue (especially if game chat or joining is impacted).

Additional changes: Note: If you do not know how to make changes within your router, then get help from someone who does (parent, or write back with your router brand and model number and ask for assistance).

2) Within your Router ENABLE the UPNP setting.

3) Another option: Within your router, assign your console a static IP address. Then set up port forwarding for the following ports: 88 UDP and 3074 UDP & TCP. This way you can keep NAT closed, but allow unrestricted internet traffic to xBox.

4) If using wireless network adapter, unplug it and run a CAT5 cable from the Xbox directly to the router. If your lag issue goes away, then there could be interference with the wireless traffic. If interference, then log into router and change the broadcast channel.

5) High speed internet and traffic: You really need high speed internet (cable or DSL), close proximity to the router and bandwidth to fully enjoy online gaming. If there is a housefull of net users (Youtube, movies, music, gaming, etc..) then you can expect lag issues.
Upgrade to a higher speed package. 3 or 8 Mbps download is fine if you are by yourself, but with lots of activity, then you need 16 to 30 speed (which is really volumetric capacity and not speed). Check your download/upload speed at www.speedtest.net

6) Make sure your Modem (not router) is DOCSIS 3 and not the older DOCSIS 2 versions. Ask your ISP to check your connection for any potential problems. They can typically read this from their end.

7) Check all cable connections coming into the house, all the way to the Modem. If DSL, then check phone lines and filters.

8) Finally, and I am sure this never happens, if surfing off of a neighbors system, then stop mooching and buy your own! ;-)

Hope this helps!

    Xbox 360 live on wireless router


    In theory you should be able to "share" your internet connection. I use a Linksys WRT54GS wireless router and I have a Linksys Game adapter on my son's 360. He has not complained about lag or slow server times unless other intensive bandwidth is being used.
