Extremely poor performance

My wireless card is experiencing high packet loss and very high 2k+ ms latency between the computer and router. this is one of 5 computers on this wireless network, and is the only one haveing these problems. the router is a d-link router so i don't think it's a brand compatibility issue.

It could be because this card is probably set at 108mbps as default, but your router maybe a 54mbps stream, therefore if it's possible set the card at 54mbps to see if there is any change. applogies if this is not the case, but unless it's a signal or driver fault, it may be worth trying in a different pc.

Packet loss


assuming that this is happening with BOTH wired and wireless....


Connect a PC to one of the switch ports with an Ethernet cable. Login to the Admin utility of the Router and go to "System Tools" at the bottom of the left-pane. it will expand, then choose -Diagnostics-, then use that to Ping yahoo.com or google.com and see if the packet loss is happening there.

If it *IS* happening there, then the problem is not the Router...it's getting what the modem is sending, so your fault would either be with the Modem itself, or with your service provider's equipment. You would call your provider, explain your packet-loss experience and they will check it out for you.

If there is no packet-loss coming-in to the Router, then :
Ensure that the antennae are straight (if the problem is wireless only.)
Ensure that you do not "stack" the Router on top of the Modem or the Modem on top of the Router. The heat from the bottom appliance will, over time, cook the one on top.

Beyond that, you can "save" the Router's configuration file, then perform a "Reset" of the Router, then Re-load the config file and check it out.....

Tip

How do latency and packet loss determine network performance and what can be...


The triumvirate of network performance metrics are packet loss, latency and jitter.

Almost all network applications use TCP (Transmission Control Protocol) to get their data from point A to point B. About 85% of the overall internet's traffic is TCP, of which specific aspect is that it completely hides the packet-based nature of the network from applications. Whether an application hands a single character or a multi-megabyte file to TCP, puts the data in packets and sends it on its way over the network. The internet is a scary place for packets trying to find their way: it's not uncommon for packets to be lost and never make it across, or to arrive in a different order than they were transmitted. TCP retransmits lost packets and puts data back in the original order if needed before it hands over the data to the receiver. This way, applications don't have to worry about those eventualities.

Network latency
TCP has a number of mechanisms to get good performance in the presence of high latencies:
1) Make sure enough packets are kept "in flight". Simply sending one packet and then waiting for the other side to say "got it, send then next one" doesn't cut it; that would limit throughput to five packets per second on a path with a 200 ms RTT. So TCP tries to make sure it sends enough packets to fill up the link, but not so many that it oversaturates the link or path. This works well for big data transfers.
2) For smaller data transfers TCP uses a "slow start" mechanism. Because TCP has to wait for acknowledgments from the receiver, more latency means more time spent in slow start. Web browser performance used to be limited by slow start a lot, but browsers started to reuse TCP sessions that were already out of slow start to download additional images and other elements rather than keep opening new TCP sessions.
3) Also you may use simple open-transfer-close-open-transfer-close sequences that work well on low latency networks but slow down a lot over larger distances or on bandwidth-limited networks, which also introduce additional latency.
4) Try to use a DNS server close by. Every TCP connection is preceded by a DNS lookup. If the latency towards the DNS server is substantial, this slows down the entire process.

Packet loss
Packets are lost in networks for two reasons:
1) Every transmission medium will flip a bit once in a while, and then the whole packet is lost. Wireless typically sends extra error correction bits, but those can only do so much. If such an error occurs, the lost packet needs to be retransmitted. This can hold up a transfer.
But if network latency or packet loss get too high, TCP will run out of buffer space and the transfer has to stop until the retransmitted lost packet has been received. In other words: high latency or high loss isn't great, but still workable, but high latency and high loss together can slow down TCP to a crawl.
2) Another reason packets get lost is too many packets in a short time: TCP is sending so fast that router/switch buffers fill up faster than packets can be transmitted.If TCP has determined that the network can only bear very conservative data transfer speeds, and slow start really does its name justice, it's faster to stop a download and restart it rather than to wait for TCP to recover.
Jitter - is the difference between the latency from packet to packet
Obviously, the speed of light isn't subject to change, and fibers tend to remain the same length. So latency is typically caused by buffering of packets in routers and switches terminating highly utilized links. (Especially on lower bandwidth links, such as broadband or 3G/4G links.) Sometimes a packet is lucky and gets through fast and sometimes the queue is longer than usual. For TCP, this isn't a huge problem, although this means that TCP has to use a conservative value for its RTT estimate and timeouts will take longer. However, for (non-TCP) real-time audio and video traffic, jitter is very problematic, because the audio/video has to be played back at a steady rate. This means the application either has to buffer the "fast" packets and wait for the slow ones, which can add user-perceptible delay, or the slow packets have to be considered lost, causing dropouts.

In conclusion, in networks that use multiple connections to the internet, it can really pay off to avoid paths that are much longer and thus incur a higher latency than alternative paths to the same destination, as well as congested paths with elevated packet loss. The path selecting process can be performed automatically: learnhow to automate evaluation of packet loss and latencyacross multiple providers to choose the best performing route.

If you loose packet when you ping your router, is or your router or your network card who made the problem. Try to ping your router with an other computer. If you still lose packet is the router otherwise is you network card. When you know where's the problem you can change the faulty device.

I bought a DLink DIR 600 wireless router and want to connect ONLY two PC to it. One is wireless and one is wired. No internet connection to www required. The wireless PC OS is Fedora 14, the wired PC...


The final solution is a factory reset of your router. You can do a factory reset by logging into the router using you browser. Go to the settings and perform a factory reset

If you forgot the router password, you ill have to do a factory reset by locating a small hold on the back of the router and insert the tip of of paper clip for about 10 seconds while the power is on. The router will be reset to out of box status and then you can ssets-up form scratch.

My router will not connect the power light keeps blinking


Check this tip out from Linksys. It is for a G VPN Router but you could use the same steps to troubleshoot. Title: Resolving Blinking Power or Diag LED on a Linksys Wireless-G VPN Router Article ID: 4982 If the Power LED on your Linksys router is blinking, this means the device is not ready. It should go off once the router completes its diagnostic test. If the Power LED won?t go off, it indicates that there?s a possible hardware problem with the router. To resolve this, you will need to perform five steps: Resetting the Router Assigning Static IP to the Computer Pinging the Router Accessing the Router?s Web-based Setup Page Updating the Router?s Firmware For instructions on how to reset the router, follow the steps below. Resetting the Router Hold in the RESET button at the back of the router for 30 seconds. Unplug the power to the router then plug it back in. If after resetting the router and the Power LED is still blinking, try resetting the router again for another 30 seconds. Then proceed with assigning a static IP address on the PC. For instructions, follow the steps below. Assigning a Static IP Address on Your Computer Most of the time, if the power LED on the router is blinking it loses its ability to assign IP addresses to the PCs connected to it, which is why you need to assign the computer a static IP address. After assigning a static IP address on the computer, check if the computer is still communicating to the router by performing a ping test. To ping the router, follow the steps below. Pinging the Router Ping test helps trace the communication between the computer and the router. The computer sends packets to the router and in return the router sends out replies to validate the connection. In this example, our router IP address is 192.168.1.1. NOTE: If you?re using Windows 98 or ME, click here. Windows 2000/XP Step 1: Click Start, then Run. Step 2: When the Run window opens, type ?cmd? in the Open field, then click OK. Step 3: When the MS DOS Prompt appears, type ?ping 192.168.1.1? and press [Enter]. Step 4: Check the ping statistics. You should get Packets: Sent =4, Received =4, Lost = 0 (0% loss). NOTE: If you?re not getting good replies from the router, it means the router is not communicating properly with the computer anymore. You can already consider the device defective. Windows 98/ME Step 1: Click Start, then Run. A window similar to Step 2 will appear. Step 2: When the Run window appears, type ?command? in the Open field, then click OK. Step 3: When the MS DOS Prompt appears, type ?ping 192.168.1.1? and press [Enter]. Step 4: Check the ping statistics. You should get Packets: Sent =4, Received =4, Lost = 0 (0% loss). NOTE: If you?re not getting good replies from the router, it means the router is not communicating properly with the computer anymore. You can already consider the device defective. If you get good responses from the router, access the router?s web-based setup page to see if a firmware update is possible. For instructions, follow the steps below. Accessing the Router?s Web-based Setup Page In order to perform a firmware update, you should be able to access the router?s web-based setup page. Updating the firmware is one way of resolving the blinking power light on the Linksys router. To access the router?s web-based setup page, click here. NOTE: If you?re having difficulties accessing the router?s web-based setup page, the router is considered defective. If you?re able to access the router?s web-based setup page, proceed in updating the firmware upgrade.

I have a Belkin N1 Vision Wireless router and its performance is poor, i have checked it via the pingtest site and it constantly has a packet loss of 20% or higher and poor stats re ping and jitter tests...


PAULUS

The first question I have is have you tried connecting to router via wired and wireless and ran the tests to see if the issue is with your wireless signal.

Then next thing to look at is connecting your modem to your computer and run the same test because the problem could be with your connection in your area. Note even through your modem is working properly you still could have bandwidth issues in your area and your ISP may not tell you that there is an issue like that in your area.

The last thing to look at is how long you have had the router for. If you have had the router for serveral years it is possible that it is just time to have the unit replaced.

Let me know if you have any more problems or questions.

Extremely inconsistent connection to router (Net Gear) & Internet


Intermittent Connectivity:
NOTE: Before following the steps in this article, check if your wireless computers have stable connection when connected to other wireless networks (hotspots).
This article assumes that all wireless computers are experiencing intermittent wireless connection with the Netgear router.
Frequent wireless disconnection can be caused by different factors such as:
  1. Wireless interference within the network.
  2. Wireless settings of the Netgear router are still set to default.
  3. Firmware is corrupted.
Reducing Wireless Interference
If you are experiencing frequent disconnection from the wireless network, it helps if you check the following factors, all of which can greatly affect your wireless signals:
your cordless telephone system (or even your neighbors’), or other nearby equipment. Try to change your router’s channel to 1 or 11 (the default channel is 6) and restart the wireless computers.
Physical obstructions: Your router or wireless computers may be losing connectivity because of physical obstacles such as walls and floors. Try to move the equipment to different locations to find a better link.

  • Placement of the router:Netgear suggests that you place your router as high off the ground as possible. When placing the router in a high location, leave a distance of two feet between the router antenna tips, ceiling, and wall. If your signal passes through multiple floors, place the router on the upper-most floor, and high up in the room.
  • Surroundings: Keep the router away from large metal objects, bodies of water (fish tanks, bathrooms), and any electrical equipment including television sets, microwaves, radios, etc.
Customizing Wireless Settings of the Router:
Having default wireless settings on the Netgear router may cause conflict with other Netgear routers within your network range.Netgear suggests changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

Belkin 54g Wireless connection problem.


This is more of an explanation then a solution, but to best explain what to do I have to first explain why this is happening. When you add security to a wireless router or ap you add extra envelopes to the packets of info being transferred, adding encryption to that makes it much slower because the ap has to encode all packets coming to you and un-encode all packets being sent to the Internet. In our time this happens very quickly, but in computer time I just described a lifetime. In addition if your signal is not 100% you might have packet loss "more slow down". Now the answer, in your ap setup pages you can setup wireless security, set this to Mac address authenication and add the mac addresses of all the network cards that have access to this ap. This is by far the fastest methiod of secure data transfer.

Hope this was some help...

Explanaition:
This delay you are experiencing is called latency. All equipment or signal processing unit introduces some latency even if extremely low.
Computer tends to be a lot worse than outboard gear.

Solution:
Look for Asio4All, this little driver will help you improve your audio input latency. And remember, the smaller the buffer size the lower latency you get.
