Wireless Networking - New Router, New Lag?

By karma1 ·
Howdy all...

While this is not my first foray into WiFi, I am still a newbie. Here's the lowdown on my problem(s).

The way my house is built, teh addition at the rear exists "outside" of the original house. This means that there is a brick 'exterior' wall between it and the rest of the house. Sadly when the phone/cable company came to wire the place for VoIP phone service and high speed internet, they chose that part of the house to do it in, less structural damage or something.

I had a Motorola wireless router previously... I'm not sure of the model number and I don't want to search for it at the moment... regardless it had a problem with wireless signal range. The main computer was about 25-30 feet away and was getting a signal strength of 30-60%. I purchased a Linksys WRT54G wireless router to replace it. It even had 2 antennae!!

I am now having issues with the WRT54G that I never had with the motorola. While the signal strength is exceptional (I'm getting 80-90% signal strength upstairs!) it has brought with it lag spikes. I play World of Warcraft and there is very noticeable lag that never ocurred before. My game will pause for anywhere from 10 seconds to 2 minutes. The motorola never caused this.

I've setup the router to use WPA2 Personal security with the group renewal rate at 3600 seconds. I've limited the DHCP pool to 5 addresses (the max number of connected devices I own) and I've gone out of my way to find info on the Net looking for a cause. I'm using NetStumbler which tells me there is no signal interference and I'm not sure what else I could be looking for.

Any questions or help is much appreciated!! I'll try my best to provide what info you require to help resolve this.

Router: Linksys WRT54G
PC1: Cyber Station NW-5411 Wireless PCI (802.11b/g)
PC2: Cyber Station NW-5411 Wireless USB (802.11b/g)

Thanks!

Encryption Overhead

by PoBody In reply to Wireless Networking - New ...

Just joined the site, but I've got a few ideas to share with you.

First, the WPA2, or any encryption, will add extra overhead to the packets sent on the wireless stream. Second, playing games over wireless has a tendency to produce more lag than over a wired connection. I'll try to explain. When packets are sent over a wired connection, via routers with a switch interface (the standard router) to router will learn, over time, the computers connected to it. This way it can determine the "best path" to the computer. This means that the router knows which port to send the data through, instead of broadcasting it on all ports. With wireless this isn't possible. Data is just broadcast and the devices connected to the network "listen" for packets with their "name" on it. This means games with heavy data flow and any other task which requires the transfer of large amounts of data will cause more lag on wireless than with wired.

Now, I know this doesn't resolve your problem, but hopefully it clears up the cause. I'll keep an eye on this post and continue to help out if I can.

Possible Solution: You could try disabling WPA2 Personal and use a standard WEP. If you do this, security is still a concern. Data won't be encrypted, which means anyone can sniff it, but it should lower the overhead. To further secure the wireless from other people connecting to it, you can enable MAC filtering on the router.

If you have any more questions, or need more clarification, just let me know, I'll be glad to help.

Hope this helps.

Hi there

by kler83 In reply to Encryption Overhead

Hello,

Have you solved the problem? I guess you already know how to open the set-up page of the linksys router right?

Try looking for applications and gaming tab, then look for QoS...-set higher priority for your game. I hope that can help.

Also I'll give you a list of items that can interfere the wireless connection ok ...

Here is a short list on common causes of interference:

WINDOW IN BRICK WALL = 2dB

METAL FRAME, GLASS WALL INTO BUILDING = 6dB

OFFICE WALL = 6dB

METAL DOOR IN OFFICE WALL = 6dB

CINDER WALL = 4dB

METAL DOOR IN BRICK WALL = 12.4dB

BRICK WALL NEXT TO METAL DOOR = 3dB

If EU uses 2.4 GHz phones and experience interference, let them try to set a different channel on their phone.

Keep it away from large metal objects such as filing cabinets.

Place the Access Point as high as possible.

If the network goes through multiple floors, try to place the Access Point on the upper floor.

If EU wants to connect while he/she is outside his/her house, place the AP near a window

sources of active interference. Anything that emits EMR can interfere, including a neighbor's wireless router.

edit: Are you positive this is wireless lag? Not an issue on the local machine? Try cabling to the router temporarily to see if the problem persists. If it isn't your system or the wireless, it could be a broadband issue.
