Problem with my wifi extendor?

Alex

I recently bought a wifi extender to reach my new desktop up on the top floor in my room from the basement 2 floors down. It works fine except sometimes it just disconnects from the internet entirely. What's weird is that it'll show I'm still connected to the extender but it just says that internet access is unavailable as if it just decided to turn off. When it goes off I check both the extender and the router and they both are fine, all greens lit. Any help would be appreciated.

Answer
You don't mention what frequency range you are in. If it's 2.4 (g or n) you may be experienceing interference from a household device like a microwave, cordless phone or baby monitor.

The signal will still be strong but the interference will scramble the packets and the encryption will fail.

Wifi problems ?? Help ?

As soon as I go into my bedroom, I lose wifi connection on my iphone but it connects perfectly on my laptop. What's going on?

Answer
Different WiFi devices vary in wireless range and performance.

Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.

All of these factors will affect your actual wireless range. As wireless connection quality varies the connection speeds are renegotiated. The WLAN connection between your WiFi device and your wireless router may start at 150 Mbps and end up at less than 10 Mbps or drop entirely.

High performance routers generally have a much better wireless range than their cheaper competitors.

However, Just because a particular wireless router model works good at one location does not guarantee that it will have similar performance in a different location due to variances in the factors listed above.

You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.

You could also try adjusting the position of the router or relocating your device closer to the wireless router to obtain a stronger signal.

If you still have a weak wireless signal you can either get a wireless extender or a wireless adapter with better range for your WiFi device.

For a iPhone you cant replace the wireless adapter like you can on a laptop, so you'll need a stronger WiFi signal.

Devices such as wireless extenders can expand your wireless range. The wireless range extender receives weak wireless signals and repeats them to extend the signal range to greater distances.

Nintendo Wifi USB Connector Issues?

Jeff B

I have had this thing for over a year now and it has started giving me issues lately. This is what it does: it connects fine, 3 green bars, and my computer says someone connected, then it disconnects me and says "Unable to connect to Nintendo Wi-Fi Connection. Confirm connection settings and access point settings."

And a 52103 error. I tried looking up this error on nintendowifi.com, checking these settings, turned off the firewall for the USB connector, unplugged it and plugged it back in, and even reinstalled it. Some days it works perfectly, but if I unplug it, it won't work for about 24 hours.

Any help or does anyone know how to fix it (or at least what the problem is)? This thing worked yesterday.
No one around me has a wifi network (I checked with a laptop a while back :P) and I have talked on my cordless phone and been connected at the same time before (recently). The microwave is off and far away and I turned off the baby monitor and it still didn't work.

I am not using a router, I am using the USB Connector (little white thing with the blinking light).

Answer
It's probably interference from a neighbor's new wifi network.

change the channel on the router - there are 11 of them, pick a new one that is as far away from the current setting as possible.

Cordless phones, baby monitors, microwave ovens also use the same 2.4 GHz frequency can can cause problems.

Having problems with wifi cutting in and out?

Brad

Lately when I've been using my laptop the internet has been cutting in and out and I cannot figure out what the problem is. This first started happening about a month ago about 2 weeks after we received road runner. I restarted my computer one day and when it signed on to the network there was a limited connectivity icon for the wireless network card.

The first thing I obviously tried was to recycle the modem and router. I turned those off and plugged the scientific atlanta modem back in that was supplied by time warner, then about 3 minutes later when the modem was booted I plugged in the wireless netgear wpn824v2 router. I had the same problem.

The second thing I did was check the WEP key, which I did have set wrong but when I fixed it, again, it was the same problem. I know for a fact it is correctly set now.

The third thing I did was update the wireless network card driver on my laptop (which is a toshiba satellite a205-s5804 btw) This did not fix anything either.

The fourth thing I did was check for interferences. I went into the room that the router is in and I sat down and the computer connected to the internet fine. I figured it was the printer we have since we just hooked it up the day before. I unplugged the printer went back into another room and thought it was fixed, untill a few days later it the limited connectivity icon popped up again.

From that day forward I have been able to reconnect the computer to the internet just by going into the room the router is in and leaving, only to find that 12hr - 2 days later it is giving me the limited connectivity icon again and not letting me connect to the internet.

I am connected using mode g and b, and it has been set like that for a long while with no problems.

Answer
The most likely cause interference from a cordless phone or a baby monitor. Go into the router configuration utility and try changing the channel.

Can a computer that needs an ethernet cable use wifi?

baby monitor interference wifi image

ROBLOX

I need to know if there is possible ANY way to make it so I can use wifi on it. I just bought a desktop computer and just assumed it used wifi. But it needs an ethernet cable...... Problem is there is only one of those ports in the house and that is the living room. I can't put it there because my mother won't allow it. So I need to know if there is anyway I can make it wifi. I would really appreciate it.

Answer
It is easy to add WiFi to a desktop. You can get a wireless adapter for your desktop PC, they are very inexpensive. Many are under 10 bucks. http://www.amazon.com/s/?_encoding=UTF8&tag=excharge-20&linkCode=ur2&camp=1789&creative=390957&field-keywords=wireless%20adapter%20for%20desktop&url=search-alias%3Daps&sprefix=wireless%20a%2Caps%2C377 There are two types, the easiest is a USB that just plugs in, the other is a card that involves opening the PC and installing in a card slot.

Unless you specifically need a wireless connection, I would not recommend it especially for a fixed device such as a desktop PC.

Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.

Wireless connection quality also varies and there is overhead involved in the transfer such as the encryption and decryption of the data used for wireless security.

You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.

For serious gaming or video streaming your best bet is a direct Ethernet connection. Ethernet is unaffected by wireless interference and will give you a rock solid, stable network connection.

If it is not feasible to run Ethernet cable your next best option is to use powerline network adapters. I wrote a review here: http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/

Is there a way to detect if someone is using a wifi jammer?

Reprobate

My internet has been out for three weeks. There have been brief periods when it's working 100% on all devices. I've changed routers three times - same problem with each one. Cable provider has been out - they say all good on their end. I had the Geek Squad out too, but they arrived during one of those brief periods when everything was working.

Could someone be jamming my wifi? I just Googled wifi jammers and apparently they exist because I came across a web page that sells them.

Is there a way to detect if someone's using one in my area?

Answer
You can download an application called a WiFi Sniffer. This will show you all the wireless networks available in your area, and include more detailed information than your OS will tell you. I've used NetStumbler and Xirrus WiFi Inspector. They should tell you what network you are connected to and what channel your router is on. Next look to see if there are any other networks in the area on the same channel. If so, you could be experiencing co-channel interference. This happens when wireless devices (such as router and access points) are in the same area and operate on the same channel. Change your channel to lesser used channel (1,6, or 11) with a weaker signal. If your devices support 5 GHz, you might also try that.

Also, there are other devices that operate in same frequency band as most WiFi devices. These include microwave ovens, cordless phone, and baby monitors. The Sniffers only work with WiFi devices, it won't tell you about nonWiFi interference sources. There is hardware and software that will do that, but it has a high price tag.

I doubt someone has a WiFi jammer. If they did, its possibly illegal (subject to local laws). In the US, the 2.4 GHz range is unlicensed, and while a device operating on that frequency IS required to accept any signal, you may NOT operate a device with intention of causing interference. If I had to bet, its interference from nearby sources, check the WiFi scanners I suggested.

Can I use old router as a bridge to boost wifi signal?

baby monitor interference wifi image

lizaroth

I have an old linksys router sitting around that I want to use to fix wifi signal issues in my house. I know you can get wired into the 2nd router when you bridge. I am just wondering if this 2nd router will be able to transmit a good wireless signal or is it just used to connect wired devices?

Should I just buy a better router or try and make this work with my old router which is laying around?

Answer
You can use multiple wireless routers provided they are configured correctly.

Wireless signals are affected by many factors including wall density, electrical interference, directional antenna range, etc.

Depending on the size of your house and the factors listed above, you may need one or more wireless access points or wireless range extenders to cover all areas adequately.

Many wireless connections also experience interference from microwave ovens and cordless phones which interfere with the 2.4 GHz band.

Just because a particular wireless router works good at one location does not guarantee that it will have similar performance in a different location due to variance in the factors listed above.

If you are getting a new wireless router try to centrally locate it up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.

That being said,

There are various ways to extend a Internet connection to areas with a weak wireless signal.

Devices such as wireless extenders that can expand your wireless range if need be. http://www.amazon.com/gp/product/B004YAYM06/ref=as_li_ss_tl?ie=UTF8&tag=excharge-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B004YAYM06

The wireless range extender receives weak wireless signals and repeats them to extend the signal range to greater distances. Some models include 4 Ethernet ports in addition to the wireless radio.

You can also use multiple routers provided they are configured correctly.

Unless you have experience in network configuration, it's not a good idea to use additional routers unless you turn off the routing functions and use them as wireless access points. Your wireless signals will interfere with each other if they're operating on the same wireless channel. A router also acts as a DHCP server to assign IP addresses, you only want one DHCP service running.

Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks. Computers that are connected to IP networks must be configured before they can communicate with other computers on the network. DHCP allows a computer to be configured automatically, eliminating the need for intervention by a network administrator. It also provides a central database for keeping track of computers that have been connected to the network. This prevents two computers from accidentally being configured with the same IP address. http://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

You'll need to manually configure the second router before placing it into service. The IP address needs changed so it doesn't conflict with the first router, the DHCP functions should also be disabled on the second router.

You'll have to connect a PC or laptop directly to the second router via Ethernet and log into it's interface to change it's IP. You'll want to change this to something that doesn't conflict with the first router but is in the same subnet.

Plug a Ethernet cable from LAN port on the first router into one of the LAN ports on the second router, Don't use the second router's WAN port for anything. Also use non overlapping wireless channels such as 1, 6, 11. You can use the same SSID for everything.

For example if you main router has an IP of 192.168.1.1 and it broadcasts on channel 1.

Set your second router as an access point with an IP of 192.168.1.2 and have it broadcast on channel 6.

Although it is not absolutely necessary, I would also reserve the second router's IP in the first router's configuration or set DHCP to assign a range that doesn't include the second router. For example if your devices had the IPs listed above and you wanted to allocate up to 20 DHCP IP addresses you could set the range from 192.168.1.10 to 192.168.1.30. This way in case the second router were powered off for some reason DHCP would not assign 192.168.1.2 to another device which would cause an IP conflict when the second router was powered back up.

Good Luck...

Is there any software or hardware that can detect WIFI noise influences?

TheRalfZer

I Have a wireless network setup, but there is a point where the wireless network get interference from somewhere that causing very slow network connections despite that Windows say that the signal strength is excellent, even radios or cellphones are acting up in that area.

Is there anything i can use to detect what it is that can cause this?

Answer
The easiest way is to use a Spectrum Analyzer. Used to be they were very expensive and only used by those who professionally work with Wifi but there are some units out now that anyone can use and afford. Wi-Spy is one of those available http://www.thinkgeek.com/gadgets/electronic/c240/
Metageeks also have several units that give a complete band view even some advanced units that are very very good . http://www.metageek.net/

In some cases a program like NetStumbler is all that is needed to find interfering AP's within range. That will give you a list of channels and SSIDs and strength of the AP's within range.
http://stumbler.net/ its just software that works with compatible wifi cards. This isn't as complete as a full spectrum scan as it won't show phones, baby room monitors, cameras etc that may be on the same channels.
