Realtek RT8191SE Lag Spikes?
Jan 10, 2013
Just recently built a new system with this wifi card in it, and I am experiencing random lag spikes of up at 2000ms when pinging my E3000 router. I've tried the stock firmware on the router as well as the tomato variety I was using. I've tried both Windows 8 and Linuxmint 14 and the problem still exists. I did not have this issue on my laptop, nor do I have the problem with my wife's laptop. Is there any sort of setting in the bios that might affect this that I am overlooking?I'm about to just call timewarner and have them relocate the cable modem to this room so I do not have to deal with wireless.

Since about a week ago, my room-mates and I have been getting lag spikes on the internet when more than one of us are on the internet at once, yet the connection is perfectly stable when there is only one active. ( Does not matter which one. )
I've run Avast, AVG and CCcleaner, on all the computers and the spikes still persist. I've also replaced my router with no results. Here's my system info and some tracerts showing the lag spikes
System info:
Tech Support Guy System Info Utility version 1.0.0.2
OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 64 bit
Processor: AMD Athlon(tm) II X4 640 Processor, AMD64 Family 16 Model 5 Stepping 3

About 2 weeks ago I have been getting lag spikes on my xbox and PC games, this never happened.I have no problem playing the game, no lag. Apart from these spikes that happen every 10-15mins.They last for about 5-10 seconds and seriously affect my game. (I get killed)
Would switching channel through the 02 Wireless internet control panel fix this? Am I on a bad channel?p.s. It is not possible for me to haveit wired, wireless only.

I've been having problems with my internet on my PC. I use it mostly for gaming (League of Legends specifically but it's also hooked up to my Xbox for internet connection), and I frequently (about every minute or so, sometimes more) get bad lag spikes when playing games. My character will freeze in place while I click wildly about and then appear somewhere else (and die or lose a kill).
The thing is, I'm connected to my Apple Airport which all other devices in the house are connected to (Wii, dad's Mac desktop, my Mac laptop), and only my PC gets this lag. Seems like a fairly generic problem but I have no idea what to do about it, so if you need more information let me know.

I have reason to be suspicious as to the game's relevance. These spikes are characterized by no packet loss, as measured by pingplotter and winmtr (more specifically, there is packet loss, but I've come to understand that because it does not continue on to subsequent jumps it's not an issue), and latency leaping to between 250 and 600ms across multiple hops, seemingly without pattern or form, for intervals
Here are some summaries of some extended pingplotter sessions. The suspicion that this is not entirely WoW related is recent, so I'm working on seeing if I can get similar results from some other sources.

I just finished installing a realtek wireless lan but I don't know why in the tray says it is disconnected. I open the config utilily but I don't see anything to make it work. I'm using vista. I check here and I click the Radio check mark but doesn't seem to make any difference.

I am playing a game, like Battlefield Bad Company 2. Every 5-15 minutes, I get 3 lag spikes. When I get the lag spikes, everyone who is using my internet, also gets it the same time as me. So my computer is not the problem.For example: I am just running, shooting people (online), and then, randomly, people are running on the spot for like 3 seconds, and then they teleport somewhere in front of them. And then it goes back to normal, then it happens again. It will happen 3 times.

I have a problem with my wireless connection. I recently installed Windows 7 Ultimate 32bit OS and bought a new NETGEAR genie router WNR2200. I am experiencing lag spikes in 1-2 second duration while playing games. These lag spikes freeze the game and send my ping sky high (ping 999ms). While browsing the interwebz I don't really notice the lag spikes because they are only a few seconds long.Changes I have made (PC):
Disabled Client for Microsoft Networks
Disabled ANOD Network Security Filter driver
Disabled QoS Packet Scheduler
Disabled File and Printer Sharing for Microsoft Networks
[code]....
Mode: Up to 300MbpsAfter all these changes and tweaks I still get the exact same problem I started out with. The above changes were recommended by users of random forums to fix wireless lag spikes. Using a cat5 cable is not preferred (and perhaps not possible) as I am renting from random people and the router is on the other side of the house.

At my university I have huge lag spikes when playing Hon (heroes of newerth) my friends are playing and have no issues. As of now, I have turned all the graphics down to the lowest settings, disabled every function of the windows firewall I could find, and ensured no other programs are running (even closed explorer) Any idea what could be causing this? (I have no antivirus active)

recently I've noticed sharp spikes on both my wireless and wired network connections, It's safe to say it's not a network card problem as all PCs are experiencing this problem. I ran a tracert and these are the results:Tracing route to [URL] [209.123.109.175]over a maximum of 30 hops:
1 4 ms 3 ms 9 ms 192.168.1.1
2 242 ms 33 ms 29 ms 10gi6-0-0-100.bras1ldv.akl.vf.net.nz [203.109.12
9.41]
[code]...
Trace complete.As you can see there is packet loss and a huge spike in ping time.

my internet has recently been spiking every 10-15 seconds constantly. Wired and wireless both experience the spike. My modem is SMCD3GN-RRR. Heres a ping to google.ca: I've called my ISP and they said everything was fine after they ran some tests. What could be causing this and how can I fix it?

I have Planet modem ade-4400 linked to a Digitus ethernet Dn 5001a that I use to connect my 2nd PC.The problem is that everytime, both PCs are connected I constantly get lag spikes while playing games.Also, seemingly on random occasions, no matter what programs I run in the background my connection gets disabled with a yellow exclamation mark over my network icon. I get a "The default gateway is not available" error once I troubleshoot, and the connection works fine afterwards.
However, recently after I updated the windows I think, I get another error that says "The connection between your access point, router, or cable modem and the Internet is broken" along with the gateway one. Also, recently, I started having lag spikes regardless of the other computer being connected to mine after the error, and once I turn on my pc. Could it be somehow related to Microsoft security essentials? Since I've installed it at about the same time when the lag-after-the-error started happening.
Error seems to happen more often when I watch something on the internet, or when I quickly browse through the web-pages, or when I'm downloading something. I'm using Windows 7, and another thing to note is that the other computer DOES NOT receive these kinds of errors, and I do believe it does not lag while playing games.The lag after the error and after I start up my pc goes away after some time.

Everything was working fine, I was able to make everything work fine. Then yesterday morning I started up my computer and it was not connected to the internet. My ethernet was plugged in and everything was as it should be. I went in to device manager and noticed that my realtek network controller was not in the device list under network adapters. I then tried to reinstall my LAN drivers from ASUS (my motherboard) which is how I got it to work in the first place. However, this time when it "finishes" installing an error pops up and says "The realtek Network Controller was not found. If deep sleep mode is enabled Please plug the cable."

My father recently bought a laptop with windows7, and while it is connected to the internet through the router, there is a lag spike every 20 or so seconds, which also shows up when pinging the router as a jump in ping. This happens wired and wireless and also affects other connections on the network (my desktop computers also get a spike in ping). I have isolated the problem to be with the laptop, because as soon as the laptop is disconnected from router completely there is no more spike in ping

I have a Realtek PCI GBE Family Controller. I recently reinstalled Win7 and it loaded drivers for the card automatically. I actually didn't notice the speed issue until I went to move stuff around on the home network.
The Device Manager lists the above NIC. Under Properties I have:
Auto Disable Gigabit = Disabled
Speed & Duplex = Auto Negotiate
I tried setting Speed & Duplex to 1.0 Gbps Full Duplex but I only interrupted a file transfer by doing this. (The Network icon in the System Tray indicated that the network connection was lost.)
I am using Cat5E 1 Meter or less cables. I have 2 PCS next to my desk with a D-Link Gigabit Switch sitting on top of one of the computers. AFAIK all ports on the switch support Gigabit.

I have a realtek wireless usb adaptor on my hp desktop that was working until I took it out of the usb on the front of the tower and plugged it into a usb on the back of the tower. Now I can't get internet at all even if I move it back to the front! My network doesn't show up under connections. Both the playstation 3 and the netbook are picking up the wireless signal from the router.

Earlier today i bought a new setup.
ASUS P8Z68-V LX
i5 2500k
Kingston HyperX 1600
Corsair Force 90GB ssd
ASUS GeForce GTX 560
OS: Win7
Everything works fine except the onboard lan doesn't work.Windows shows that there is no cable connected even though it is connected and it works. Currently I'm using the cable to write this on my laptop so that's proof that it indeed works. The bios settings for the adapter are set to enabled. I have tried the weird stuff, like unplugging for 30 min and starting again and reseting bios and holding the powerbutton for 10 sec with powercable unplugged.The cable shows that it's connected when i set speed and duplex at 10MB/s, full or half duplex, and I can ping the router but the internet eludes me.There has been no thunderstorm in the last 23 hours, I have tried the latest lan drivers from both Realtek and ASUS, there has been no windows update to mess with the system and I've tried formatting and setting up windows again.

It has always been the case with my laptop and another usb N adapter I bought a while back but this time when i upgraded my PC and got a DWA-552 adapter and the problem occurs again I was forced to try and debug it.PingPlotter had a constant ping check on my router's network address every second, every few minutes and sometimes seconds apart there would be 100+ ping spikes which always correlate with troublesome lag spikes in-game. And that's with Roaming Policy set to very low. Once set to normal it got much worse with 500+ ping spikes, and just to cement the correlation I set the policy to very high and 1000+ ping spikes happened.Could it be that DIR655 incorrectly reports to the adapter that it is about to drop the connection forcing a roam that results in nothing but a latency hiccup? I am not well versed in wireless mechanics. These ping spikes are often accompanied with packet loss.My DIR655 has several G cards connected to it (which work fine btw, my 552 seems to work fine in G mode too though I haven't tested it extensively yet - may be forced to since dir655 appears to be bugged with N mode) and several N cards that aren't used for gaming so this issue has never been a problem before.

I have a Gigabyte motherboard that ive just installed into my dads new PC and the gigabit LAN has started taking 60 seconds to connect to router, very annoying...sitting with browser open waiting for it too connect... the issue seem to first appear during windows updates, i uninstalled device driver, rebooted and reinstalled the driver off disk... this sorted the issue.. THEN windows installed more updates, however these were nothing to do with networking (Office updates) and its back ...ive tried downloading the driver from gigabyte (newer) but still the problem persists...
Core-i5 2500k
4Gb 1600Mhz RAM
GTX 460 OC
60Gb SSD Vertex 2E

This has been a problem for quite a while now, jumping from Shaw to Telus,I have completely exhausted, and I have no idea what's wrong.I live in a household with another family, and we share internet connections, Telus Fiber Optik, as of now. Me and my brother both have our own computer and are connected via wireless adapter, and the other family has one laptop with wireless connection.
The problem would be that randomly, the internet would slow down considerably, with pings going insanely high, like over 9000ms (not joking).At first,I thought I was just too far away from the router.So I moved to a room directly under the router, and the internet was completely fine for around 1 week, then the random ping spikes started to happen again. Now, I've tried tweaking wireless settings, and checking to make sure its just not my wireless adapter, however my brother's adapter is new, but it has the same problem too, so I doubt its the adapters fault.

I bought a reconditioned Dell Inspiron 1000 which had the above loaded. In fact, everything was ready loaded on the laptop, so I do not have any disks. My laptop started jamming and so I closed down all things open on it, which unfortunately included closing Realtek (which seemed to be always open). I then could not 'reopen' the Realtek stuff loaded, it wouldn't let me.I am using a Belkin wireless g card in the laptop which came supplied with it. I thought the Realtek stuff was to with this. My internet connection keeps failing for no reason now.I don't actually know what the Realtek software/drivers/whatever were doing.

I have just purchased a new laptop (HP Pavilion G series) for my studies at university. The wirless works fine when I am connect to my network at home, but I am only able to connect to the university's network when an ethernet cable is plugged in. Everybody else I know, who has a similar setup to myself has no problems connecting to the network without the ethernet cable and I was curious as to why this might be.
I am running on Windows 7 and the wifi adapter is a Realtek RTL8188CE 802.11b/g/n
As I say I am quite a rookie when it comes to computers

I recently replaced my harddisk and ever since I've been getting BSOD's whenever I try to watch a video online (no matter what website I'm on). I'm pretty sure it's not my GPU, because I can watch my own videos just fine. It could be the RAM,ause I ran Memtest86+ for 7 passes and it found two errors, but I have no problems playing games. So, I'm thinking it's my network-driver (Realtek) even though I already (re)installed the latest version[CODE]

i've got a Dell laptop and a few months ago i started experiencing higher ping on some games and some spikes on the internet, at first i blamed my isp but this has continues since then and my brother has reported no spikes or ping increases in the last weeks. I experience a 120 ping on speedtest.net (on average) to servers that i used to get up to 20 ping on and i experience 200 ping on league of legends servers that i used to get 100~ ping on.My laptop is running on windows 7, using panda antivirus and spybot search and destroy (i uninstalled mcafee).
