Wireless N issues DIR 655 + wifi link 5300

So, I have quite the issue with the aforementioned equipment. Basically, the issue I am having is that my wireless N band LAGS to all hell. If i try to play an online game i see something like 300-500ms latency, stuttering, etc. (on a 30mbps connection no less!). The G band however, shows me latencies more around 20ms-70ms, lag-free connections etc - which is all fine and dandy but I want the comp to comp speed of the N's 300mbps.

I've tried many things, changing the channel width to see if running on the narrow 20 would help at all, nope, tried all possible permutations of security settings (yes I know anything but WPA2 turns off N), Heck - I even tried putting my comp in a DMZ, but still experience the lag. I've tried adjusting the MTU a bit to no avail. Tried disabling QoS, I really troubleshooted almost any setting i could think would have any *remote*effect. If anyone has this combination working lag-free, or any ideas on getting it to work, DO let me know. I can surf the web sort-of-okay on the N band, but gaming is a no-no. And d-links tech support...oh gosh (rolls eyes).

 

How many other comps are on this router? All using Draft-N? Is it close to appliances? A lot of things run off 2.4GHz? Certain chipsets dont work well with others because of the Draft-N versions. Here are some example chipsets Atheros, Intel and Broadcom and mixing them gets worse results. Firmware and Drivers updated? What kind of connection is it? Are you in a neighborhood? This is a start.

 

i've run this as the only comp on the router, or 2 and a ps3. It isn't close to any appliances, nothing else is running at 2.4ghz. There are a couple access points in the area but no other running N (which has a tendency to destroy everything else running at 2.4ghz in the area with interference anyway) my drivers are fully updated, as is router firmware. It's an intel chipset, another laptop has an atheros but ill experience the same issues regardless if the other is connected. It's a cable connection (30mbps down/2mbps up)

 

DIR655 is a great router from what I hear. Just trying to eliminate possible problems. Direct connection to the router ports is ok(wired)? no lag? Do you know if anyone else is connecting to it because wifi is shared? Out of ideas until I get off work....someone should come along and help out......

 

Have you checked D-Link's forum and to see how to get the max speed for the DIR 655?

 

No lag when connected with wired or running any combination of g (mixed g, b), etc.

Yeah I'm pretty sharp on how to configure the router, my connection throughput with N is 300mbps but the real-world performance is LAG. The router is secured with wpa2 and AES cypher. Once again i tried even in a DMZ and without any security as well, still get the lag. I can see that no one else is connected to the router through the router interface itself, it's quite robust.

Please spew ideas ill let you know anything ya need. I'm not exactly a network noob

 

Disable QOS if enabled, see if that helps...did on my 855. There is a post about it somewhere on D-Link forums.

Also, if I may suggest TCP optimizer at Speedguide.net: http://www.speedguide.net/downloads.php ; it's a very nice app that eliminates/improves a bunch of latency/speed problems. If you are knowledgeable, you can configure your own settings. If not, there is an auto-configure option based on a few simple input parameters.

 

Yeah I've tried that as i considered it could be a suspect, the 855 is a very very nice router... I'm thinking most helpful would be if someone with the same router/NIC has it working smoothly or if they experience the same issues..

it seems that maybe sparkyman could be the one (if he does indeed use a 655). I'm assuming the internal radio is the same for all the bands and not split for like g, n, b, etc... because then there could be a possibility that the N radio is defective... when i get home tonight ill be able to provide any info about the hardware too

 

Im at break. Have you turned off power saving mode on the wifi adapters? I have not used the dir655 router sorry but I have many friends that use it. I will ask them about it and repost. QoS is sometimes a problem if not setup correctly.

 

Man, I totally missed the QOS part in your first post, sorry.

Try the TCP app I linked too. My wife liked the improvement in performance on her laptop so much, she actually...oh well, won't go there. But it should help reduce latency and packet loss issues.

 

yeah i tried with the QoS off and i keep my adapter power savings off too. It's actually doing it with high performance activated...weird.. it's quite the oddity.

 

I struggled with an 855 for over a year and finally gave up. Dlink support is subpar for the most part. I am now using a Linksys WRT610N and get over 300mbps with the 5300. Now I am not saying that Linksys is much better but the reality is the thing works with a lot less frustration

just my two cents

 

Run direct wired connection for these webpages. Run these test several times and than even in safe mode. Trying to eliminate your ISP and modem. That way we know its your router.

Also I talked to a few friends with dir655 and they all have had problems. Firmware versions (A2 A3), QoS failure, and even Vista. One of them actually went back to windows xp and it went away.

 

well, my connection is very fast and smooth with wired and/or 802.11g wifi, i do doubt my 30mbps connection is causing an issue with just my N band in particular . Something seems quirky. on g or wired my internet is smooth, speedtest.net gives me consistent 20-30mbps results, game latencies are about 20ms-70ms, etc. N band I'm looking at jumpy benchmarks, 500ms+ latencies, etc. It's definitely an issue with the router...and im not so sure it's the configuration

 

bump, i still haven't resolved this issue if anyone has the dir 655 + wifilink 5300 working together with great latency on the N band

 

To share my experience:

I recently bought the Asus G51 (which comes with a 5100). My wireless connection had been very unstable. Streaming video will also pause to stop after a few seconds. My old laptop, the thinkpad T500, which has an intel 5300, was able to get stable signal without any issue.

I thought the issue was caused by the 5100, so I swapped it with an intel 5300 which I bought from Ebay. Still the same issue.

So after having tweaked all possible setting on the adapter (transit speed, band width etc) and on the router (qos, channel, band width, encryption etc), I decided to buy another well-reviewed router and see if it's the adapter that causing the issue.

To my surprise, my new router (the Belkin N+) now gives very stable N speed connection to my laptop. I haven't figure out the exact issue, but I've heard the DIR 655 has a "friendly neighbor" feature that may reduce the wireless signal if it detects other networks closeby... I am guessing my neighbor *new* network may have caused the DIR 655 to lose it's strength.

 

You just solved your problem a few posts down - you've set up WPA2 / Encrypted security on your Router. It is a known fact that WPA2 and gaming servers do not get along. The other likely problem is that your Router isn't setup for Port Triggering/Port Range Forwarding for the games you're playing. Though that wouldn't cause a problem with video streaming, the security will, especially on PS3 gaming.

Assuming the gaming problem you're describing is PS3 related, you must have your Router setup for Port Range Forwarding/Port Triggering for Sony Published Games, as well as for the Playstation Network, in order to have proper PS3 - PS3 communications when gaming online. Though the information is listed on the PS3 Support site (do a search on Port Setup or Port Forwarding) I posted a long, detailed how-to Router setup on the PS3 Forums for Killzone 2 not long ago, since it was apparent that most of the problems people were having were due to port setups and security.

The other issue is the the PS3's internal adapter is Wireless G -if your Router's Wireless Mode is set to N only, you're screwing yourself. You have 2 options - either run in Mixed mode, or change everything so that it has a Wireless N adapter.

The way around the Security issue is to turn off WPA2 and use MAC Address filtering - that alone should increase help your problem somewhat. But don't forget that it's not just Router's Wireless Mode that must be set - the Adapter must be setup to match the Router's settings. I know you can't access the PS3's native installed Adapter, but you can get around that (and you problem) by installing a WGA600N gaming adapter. It plugs into the PS3's Ethernet Port, and when you select Wired in the Network Setup, it bypasses the internal adapter, connecting you at N speeds to your Router and avoiding an Mixed Mode issues.

If you're not familiar with MAC Address filtering, it's simple enough - you put the MAC Address of every network device you wish to have access to your Router on the list, and anything that tries to access your Router that's NOT on the list will be denied access. I've had N Routers since they became available 3 years ago, and I can tell you that the difference is noticeable.

I just worked with someone who responded to a post of mine (how to setup Routers for PS3's Port and QoS setups) who was having numerous network problems. Since following the recommended settings so far he now hasn't had any problems at all. You might want to check my post on the PS3 Forums - it has a lot of info that'll probably help you. Though some of the info is specifically for Linksys Routers, the Wireless and Port data is the same regardless of the hardware you have.

ROUTER CONFIGURATION/SETUP

It's important to note that even with the best equipment, you'll never see the top advertised speeds that N is capable of - I myself have never seen higher than 270mbps, and that's on an external USB Dual-Band adapter on my 5ghz band. Advertised and reality are 2 different animals.

Remember to set your Adapter's settings by accessing the Advanced Tab through the Adapter's Properties Window, either through the Manage Wireless Networks Window or through the Device Manager. Make sure that it's set to Mixed unless you decide to change everything to N. Until you do, you're going to have speed issues - remember that your network is limited by the slowest device, and in your case you have at least one G adapter - your PS3.

Something else to try - download your Router's current firmware version (even if it's the current one you have installed), save your current configuration, then flash the firmware with the current revision. It's standard procedure for Linksys Support to flash firmware on their routers when speed is an issue. Whether D Link does or not I don't know, but I do know it helps to clear out any bugs. Restore your configuration setup when you're done.
