Network Lag Network Issue Help/Solutions

Your phone should never interfere with your ADSL signal if setup correctly. Make sure you have an ADSL filter on every phone line that is plugged in. Not just the one that you connect to the modem.

how can i get rid of my lag

I find sometimes its the PS3 WIFI that's a bit crap.
my was and now i hardwire an ethernet cable to it from my modem/router. No lags spikes or anything anymore.

sometimes its the modem/router's WIFI range that just isn't picked up well enough for the PS3 internal antenna.
you can buy WIFI range extenders, access points and even larger antennas (like 5 or 7db gain) as usually standard modems are only 2 or 3 db.

yeah that's PoE (Power over Ethernet) - i've always been sceptical of this tech, but it seems to work okay so i can't bag it coz i've never used it.

my modem is less than 5meters from my PS3 and WIFI is crap, however at my mums place (before i bought a house), i had a modem with an external router with a larger antenna (5db) and the PS3 in the shed out the back (a good 30meters away) and was better than what i have now which is a inbuilt wifi modem/router - no facility to put an external antenna on this modem, so i've just hard wired the bugger and it's working so

Hi guys, I know a few people have been dealing with connection issues , I know I have. Found me a nice application (DNS Benchmark) to test a number of different DNS servers, very simple and easy to use. It will tell you the best DNS servers to use so you can configure them in your router. You can download it from www.grc.com/DNS/benchmark.htm
Might help diminish lag issues and server unavailability.

Somrthing extra i've noticed is that the times i have had D/C's,that the ps3 is registering a - as the NAT type. Pretty well eliminated all problems by reseting the connection settings each time and doing same as Cyberstig's post after that.

Check your ping time. You can have download speeds of a billion Mbps,but if your ping time is 235 ms, you'll have lag. These are Extreme figures just to make the point. If your connection is stable,try changing the profile to "low latency",however if your connection has stability issues normally,this will increase. Low Latency takes out most of the error checking to speed things up,and is really only an option if you are within 2.5km of your local exchange.

If you are using Mobile Broadband,then all you can do is get a high speed dongle(21Mbps),with a powered external aerial. If you can get maximum possible reception,e.g. 5 bars on Vodafone,you can virtually eliminate d/c's,as they occur when the MBB tries to shift from the band it is currently using to the other if it has a stronger signal. If you're on 5 bars it won't try to move at all. You will have problems between 4pm & 8-9pm,as everyone does their facebook ,twitter,etc on their way home from work,after school,etc.

If you are close enough to a tower you'll find it works well,but if you are gatewaying through your computer,be sure to turn off all update features,etc,that may interfere. It's not ideal,but i used a setup like this for 18 mths,(no adsl available at house was renting) and generally all went well,but mics can only be used in smaller rooms,like less than 10 players.

I have a video's of speed tests, one showing 10,831 Kbps Download,4576 Kbps Upload,with a ping of 20ms, which my ADSL2+ connection is yet to beat! except for on ping,which i get 10-15ms,depending on the day!

Bottom line though is that Sony's position is "we do not support MBB",but it does work if you spend that little bit of money. Don't even waste your time with the base model dongle modems or pocket wi-fi's

These are ways that i personally have found work well,and part is a repeat of Cyberstig's post

1.If you are being forced to use Mobile Broadband,(Not officially supported by PSN or recommended by me,but i know there are situations that can make ADSL impossible,i've been there), you can obtain a stable connection by doing the following,
1.Obtain a Hi-Speed Dongle,21Mbps rated with an external antenna port.
2.Obtain an aerial. If you are within 500m of a relay tower you can use a powerless one,but i recommend using a powered one,as it makes up for the length of cable used to get it outdoors. With a powerless one they normally have a magnetic base,which if you sand the paint off of the underside,(just enough for the base of the aerial to get a clean connection) your gutter becomes a BIG aerial,but still point it at the tower Using a powered one only requires pointing it at the tower.
3.Connect your PS3 to your computer by ethernet cable,and enable internet sharing.
4.Shutdown as many programmes as possible on your PC or laptop,especially Automatic updating.
5.Use your IP's Connection page to adjust the aerial to have maximum reception,typically 5 bars.This is key as most d/c's while using MBB are caused by bandshift,e.g. On Vodafone they use 850Mhz(900 in some areas) on their new 3G network,but if the signal is better on their 2100Mhz band it will shift automatically,causing immediate D/C. If you can get Maximum reception on one band it eliminates the need to shift bands.
6.You will still suffer occasional D/C's,but you will find they mostly occur during Peak Hours,i.e. 4pm-8pm
7.Lag will only be an issue in rooms hosted by europeans. When i had to use MBB,(Mid 2010 to late 2012) I worked all this out by trial and error,& eventually got a stable connection with a Ping of 22m/s and download speed 10Mbps and upload 4.5Mbps,more than adequate,but will not handle large rooms & Mic at same time,only up to about 6 people with a mic,but in general i recommend no chat.
8.Turn off your firewalls & antivirus. As you are basically only using your PC as a router,you don't need them on,but disable remote & wireless connection functions
9. Set your PS3 network settings using the Easy mode.
10. Don't waste your time with Pocket Wi-Fi's or similar,they get too hot if you have them plugged in,and only last an hour at best on battery mode.
11.Use a fan to cool the USB dongle if it is getting hot,Overheating=Lag

Now to the PS3 side of things.Even with ADSL2+ Broadband you can still have D/C issues other than the PSN inflicted ones. Call your IP and find out how far you are from the exchange.If you are more than 5km from it DO NOT use the Low Latency profile,go for the most stable profile and ask your IP to sacrifice some of your download speed to raise your upload speed. Use Ethernet connection to your Router,not wireless,a lot of other household appliances cause interference,e.g.,i can turn my PS3 on with my Senzu 3DTV remote with the blue teletext button!
The quality of your router makes a huge difference,especially if there are multiple users. A$100 Netcomm,Netgear,Belkin,etc say they handle multiple devices,and they do but at a severely reduced speed.

As Cyberstig suggested using a particular start up procedure makes a Big difference. Every time i have had issues since getting ADSL2+, i've found that the PS3 has inexplicably lost the NAT type and was displaying a - instead of 1,2 or 3, so here's Cyber's solution mixed with mine.

1.Reset your router
2.Turn on PS3
3.Re-scan your network settings
4.Load GT5
5.Clear cache
6.Enjoy D/C free racing!!!!

The only times i've been D/C'd since adopting this startup procedure is a total of 3 since February,One due to a power brownout,One because the entire room crashed,and one fair dinkum one,which really adds up to One D/C in 5 months,so i can Testify to Cyber's Procedure.

If anyone has more questions about the MBB connection part feel free to message me

Hey check this out, might help,
The 'Race Quality' option is available in-game to the person hosting the lobby. For personal lobbies it is set in your lobby options, and for public lobbies it is selected when the lobby is created. It's function is to determine how often data is sent between the players connected to a lobby. If a player cannot keep up with the rate of data transmission then they may experience lag, they may appear to lag to others, they may cause lag for others, and they may get disconnected from the lobby.

To help those on slower connections the host can set the 'Race Quality' to either 'low' or 'very low'. That way the data transmission rate should be easier to keep up with resulting in less lag and less disconnections. Note that lowering this setting will not necessarily affect the visual smoothness of racing for those that have no lag/connection issues. I've run two events this week, one on 'very low' and the other on 'very high', and there were no visual differences in the movement of the cars.

The voice chat feature also has various quality options as well as the ability to disable it entirely. Voice chat requires bandwidth, so you can obviously help those on slower connections by reducing the quality or turning it off.

Worth a try
