WRT150N v1.1 Wireless connection is slow

I just recently set up a WRT150N V1.1 router up for my girlfriend. Setup was easy got everything connected just fine. Both her and her roomates laptop and the Wii all can connect with full signal strengh. The issue I am having is with the internet connection. It is brutally slow. One of the laptops is G and the other super G. Both connect at the appropriate rate. However when I run a speed test their internet connection is coming in around 200kbps. So I decided to grab an ethernet cable and hard wire it into the router. I did that ran the speed test and it resulted with 22mbps. Tested multiple times both wireless and wired on both laptops with the same result. I have an N card in my desktop that I may lug over there just to see if that makes a difference. I am just curious if there is some settings that I can play with that may have an effect. I have not checked to see if there is a firmware update available, I will do that soon. Any help would be greatly appreciated, thanks.

It sounds like all your girlfriend's wireless devices are wireless g -- is that correct? If so, set the WRT150N to "wireless g only". Also, it sounds like your computer's software firewall might be the problem -- temporarily turn it off and see if that corrects the problem. Alternatively, set the computer's software firewall to "trust" 192.168.1.1
Even though your computer shows "full signal strength", you can still be getting lots of interference from other 2.4 GHz devices. See below for more info on how to correct this type of problem.
There are many causes for poor wireless connections, and many solutions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4. If your router has settings for "standard" and "wide bands", set them to be at least 2 channels apart. For example try standard band on channel 11, and wide band channel 9.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your wireless card.
Some users have reported improved wireless performance by switching to WPA encryption.
If you continue to have problems, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps. For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

Dropping Wireless Connection & Speed Slowing Down

Hi,
Up until a week ago I had two BT lines, I will call them line 1 and line 2. Line 1 (front room) was used purely for phone calls, and line 2 (middle room) had Broadband activated on it. When it came time to renew the yearly line rental I checked and had it confirmed by BT that the available Broadband speed was faster on line 1, so I decided to cancel line 2, and move my Home Hub 4 into room 1 having arranged to activate Broadband on what in theory should be a line that gives a better speed.
My current problem is two-fold. Firstly I am not yet getting the line speed that I was expecting. I have spoken to the Technical Help Line, and understand that following the activation of Broadband on the line in Room 1 I should wait 10 days for the available speed to stabalise. Currently I am 7 days on from line activation.
A few days ago I was getting download speeds around 2.70 Mbps, with upload speeds around 0.38 Mbps. The IP profile for the download speed at that time was set at 2.77 Mbps. The IP profile for the upload speed was set at 0.45 Mbps. Over the past week I have done numerous speed checks and found that the speed did vary, as might be expected, but was generally always around these figures. Because of the line check speeds I was given by BT's own staff I was expecting the available speed to get better, not slow down! I was originally advised to expect line speeds of between 3.5 Mbps - 5.5 Mbps.
Over the last 24 - 36 hours the speed has slowed down, and a few minutes ago these are the figures I observed:
Download speed achieved during the test was - 1.3 Mbps
For your connection, the acceptable range of speeds is 0.8 Mbps-2 Mbps.
IP Profile for your line is - 1.33 Mbps
Upload speed achieved during the test was - 0.34Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.45 Mbps
Line speed then is one issue, but there is another.
My second, presently very frustrating problem is that even though the Hub 4 is consistently powered, and maintains a steady Blue light showing that Broadband is available, my wireless connection that I receive from the Hub keeps dropping. I should add that the distance from the Hub 4 in Room 1 to where I work with my laptop in Room 2 is only about 15 - 20 feet. I used the old Hub 2 until a few weeks ago, and neither my daughter on her laptop, or myself, had any problems with 'dropping' the wireless signal, whichever room we were in, or even if we used our respective laptops elsewhere in the house. I was convinced enough by the publicity 'blurb' to believe that Hub 4 was more reliable, with fewer drop-outs. So far this has not proven to be the case.
I know that I need to wait a few days more till the 10 days are up, but would really appreciate some kind soul commenting on the above. I have looked at the Logs, but without knowing what segment would be helpful in aiding a diagnosis of my two issues I didn't want to provide unnecessary information. So if any particular element of the Logs would be useful, please let me know.
Yours in hope,
Alan

Hello again,
With your help I was able to locate the place to change the channel manually, which I did, thanks for that. It only resulted in a marginal improvement, but any improvement is good I guess.
HH4 has now been showing a steady connection for three + days, so, as requested, here are the noise stats:
16:14:16, 26 Nov. ( 76.170000) DSL noise margin: 22.00 dB upstream, 12.20 dB downstream
16:14:16, 26 Nov. ( 76.080000) DSL line rate: 448 Kbps upstream, 3104 Kbps downstream
I have done several speed tests and they all show broadly similar results, namely that my download speed is usually around 2.67, whereas my IP Profile is set at 2.74.
I don't know whether this is worth mentioning but I only have an old style BT socket on my line, not one that has a test socket inside, so I can't do any of the tests using that facility.
Although my broadband connection has been stable and active on the HH4, as far as using wireless to connect my laptop in another room I do still get several dropped connections each day.
Even when I am connected to my HH4 by wireless, and my signal, as now, is only in the four bar bracket, by looking at the other Networks that are active in my street/area I can see, although it is rightly secured, that someone is using a HH3 and the signal on that is powerful enough to register a full five bar (excellent) strength on my laptop. How near or far away from me that user with a HH3 is I do not know, the point is however I can receive a more powerful and consistent signal from their Hub than my own. I must confess to being puzzled by that. What could be the reason?
Is there any further help or guidance that you can give that might assist in raising my IP profile, in the hope that my speed might increase? Or do you have any further suggestions as to how I might reduce the noise on my line to a more acceptable amount, so that my signal might give me a better wireless connection?
Thanks again for any advice or help you are able to give.

Alan

1415 fnw printer wireless connection extremely slow or not working with OS X, works with windows

The wireless connection to the printer is either extremely slow or not working at all on OS X Yosemite. It shows up in the list of printers in Bonjour in Safari, and I can connect to parts of the web interface if I wait a very long time. However, I cannot add the printer as a new printer in System Preferences even though the printer shows up.
I have upgraded to the latest firmware. The WiFi indicator on the printer is on, "green", and it has a reserved IP showing up in my router (ComCast). It seems that Windows machines can printer to the printer wirelessly without a problem.
Any help appreciated.

My wireless connection is slow

I've had my new apple for only a week or so, and the wireless connection is really slow, even when it shows it at full strength. My four year old HP laptop downloads files just as fast or faster than my apple and it shows that it's connection is very weak (almost not there). Any ideas why this would be?

Having read through the forums - and had problems on my machine - I think there are three different problems to do with Wireless on the new Intel Macs.
1) Poor Bluetooth reception (Mac Pro only)
a handful of people seem to have the wrong antenna wire connected to the bluetooth module in the Mac Pro.
2) Failure to auto-connect to a base station. Following Sleep etc.
OS X maintains a list of preferred WiFi base stations to auto-connect to. Something is broken with this feature, so the Mac fails to automatically re-connect. This can be corrected by removing the name and re-adding. (A more radical form of this solution seems to be deleting the prefs file from the system)
3) Slow or very slow wifi connection speed. This seems to be affecting iMacs and Mac Pros fitted with the very new Draft 802.11N wifi boards made by
Broadcom. BCM94321MC. Which shows up in System Profiler as (0x14E4,0x87)
Macs with this problem show a number of issues:
* Inconsistent ping times even to a local machine.
* Low signal strengh indicator (even when next to the the transmitter). In my case I see 3 out of 4 bars in the menu indicator. And 5 out of 15 bars in Internet Connect.
* Throughput that never gets better than 460Kbytes per second (3.6mbits) Note that this might be faster than your internet connection, and you might find this speed acceptible or not notice the problem. However the card should be able to deliver 54-27 Megabits across a local network - almost ten times the speed it manages at best.
I think this last problem could be a manufacturing defect, or something wrong with the firmware on the card. The card behaves identically when running under Windows. Which rules out the driver. Under Windows the signal strength appears full - but the throughput is still poor.
I am hoping a firmware update will resolve this issue. But if you need fast wireless in a hurry, a Wireless-Ethernet Bridge plugged into your ethernet port might be your best option.
I'd like to hear from anyone who has one of these cards and is getting more than 10megabits through it.

HT201068 Updated Remote Desktop Admin 3.8 and now my Time Capsule wireless connection is slow

I recently updated to Remote Desktop Admin 3.8 and since then, I have had issues with the wireless connection from my Time Capsule.
1) I reset modem and had no change. 2) I then plugged the ethernet directly into my Mac and the connection was great so it's not the service or modem.
3) I hard reset the TC and when it came back, the speed was good but went back down after a few minutes. 4) Plugged ethernet directly into Mac and again, the speed was great so it is definitely the TC.
Would love some help resolving this. Hoping I don't have to get a new wireless router. Maybe the TC is too old? I purchased it in 2009 or 2010/ Current version 7.6.4

Most home routers running 24/7 are good for about 3years.. your TC has now managed to survive 6 years.. it is well and truly time for a replacement. Simple fact is, it should be dead by now.. so you are living on borrowed time whatever happens.
Why RDA would slow the wireless I am not sure..
Are you running Yosemite.. ?? I tend to point the finger at the OS rather than an application.. mind you if the amount of data going back and forth has increased.. what appears to be slower wireless might actually be something else.
Apple has reasonable wireless analyser built into the OS since mountain lion.. it is well worth using.
http://osxdaily.com/2012/07/31/wi-fi-scanner-mac-os-x-mountain-lion/
I recommend doing a few things like short names, no spaces pure alphanumeric for everything in networks. Passwords also must comply. Apple made changes to network protocols since Mavericks but did not fix the names being recommended in the airport utility.. and still haven't which break their own rules.
And fix names for bands differently so you can force the connection.. plus setting channels.
However in a unit of that age.. it will have pretty weak 5ghz and that is what is important for high speed wireless.. Apple have hindered 2.4ghz since forever.

Wired connection thru TC FAST. Wireless connection VERY SLOW.

I have a Time Capsule (purchased in the Spring, so it 's the generation before the one that's out now), and 4 Airport Expresses. I'm also using a MegaPlug 85 Mbps Ethernet adapter kit. Whenever I turn off the airport card on my laptop and plug directly into either the MegaPlug or the Time Capsule, my connection is the fastest that it's ever been. Pages come up with barely any perceptible wait. When I unplug and use the Airport to connect over my wireless network, it's much, much slower.
I used the assistant tools to configure the Time Capsule and the Airport expresses. Are there any settings that I should manually change to improve my speed?
Is it possible that I have too many devices on the network? Currently, I have 3 Tivos that all use wireless to download programming information. We have an XBox connected to one Airport Express. Then we have 5 laptops -- 3 or 4 of which may be in use at any one time.
Also, our Internet provider is Comcast Cable in New Jersey.
Thanks for your help!

That many AirPort Express units can cut your network performance all by themselves. Only one of them can transmit at a time. In addition, the extra relaying of traffic that the AirPort nodes have to pass among themselves cuts into the available bandwidth.
What model AirPort Express(s) do you have ("N"-capable or "pre-N")? That can make a difference in how you configure your network. Can you identify Wi-Fi band (B, G, or N) capabilities of each of your Wi-Fi clients? That might also make a difference in your options for improving your network. Are any of your non-laptop Wi-Fi clients close enough to an Wi-Fi node that you could connect them with an Ethernet cable?

Satellite L505 - Wireless connection is slow

Curlie028,
I'm having the same problem with a brand new Toshiba Satellite L505 - Windows 7 64-bit with the Realtek RTL8191SE Wireless NIC.
I've tried EVERYTHING.
[http://www.dslreports.com/speedtests/] starts out at about 1480 kbps dowload speed then rapidly drops to less than 300 kbps. LAN cable gives 1480 kbps download speed all the time on my DSL connection. But when I use the Realtek wireless NIC, the speed starts out fast, then tapers quickly to < 300 kbps.
My daughter has a Satellite A500 (not L500) with a different wireless adapter. Sitting side by side anywhere in the house, her laptop, when accessing the same wireless router, always enjoys nearly 1500 kbps as measured by www.dslreports.com/speedtests/ - but not so with my laptop!
I've done all I can to investigate this on my own - much like you - driver updates, BIOS update, turning off all the Norton Internet Security Suite stuff, different browsers, you name it.
I've even tried modifying the "netsh int tcp set global" parameters, running the speedtest repeatededly as I made changes following the steps outlined at this website: [http://www.speedguide.net/read_articles.php?id=2574]
The only thing left to do is to call Toshiba Support and start riding them relentlessly until something gives.... I don't want to return the laptop. I want them to FIX THE PROBLEM!
Mike

Hi buddy,
You wrote that you tried everything like driver update, etc.
But it would be interesting to know which driver you have installed. Please install the latest WLAN driver from the official Toshiba page and not from Realtek directly. All drivers from the Toshiba page are pretested for your notebook.
Check this!!!
Furthermore it would be interesting to know if you run factory settings or your own Windows installation.
The Norton Internet Security software isnt so fast. I would recommend uninstalling it and choosing another AntiVirus like AntiVir. The Firewall you can use the Windows one.

WRT400N router Slow wireless connection

I just purchase a Simultaneous dual band N router Model # WRT400N.
Works fine but when you connect a wire PC and download any type of file, the wireless connection slows down dramatically. Also when playing online thru a wire connection, the wireless connection is slow.
Any ideas how to fix this problem?
There is no new firmware to update, sometimes that helps.

On the Linksys Setup Page,Under setup tab MTU is set to "Auto"..Change it to "Manual" and reduce the size to 1364 and Click on save settings...

Why is Wireless G router slower than Wireless B?

I have a wireless B router (BEFW11S4 V4) that is dropping my internet connection sometimes on a daily basis. To restore it, I have to unplug the power and plug it back in. It's a pain and interferes with my work, so I purchased a wireless G router (WRT54G2) to replace it. Setting it up was quick and painless, but slowed my internet to a crawl. I know that wireless connections are slower than wired, but a direct connection was about 10 times faster (according to several online speed tests) which I find unacceptable.
I have since removed it and gone back to the older faulty router to restore my internet connect to a speed that at least allows me to do my work. I was not unhappy with my connection speed before. I only replaced the router because it was dropping the connection, but I cannot understand why the new router was so much slower.
Any thoughts, hints, or suggestions before I return the new router to the store?
Thanks!

1) What Internet connection speed are you paying for?
2) What Internet connection speed do you get when you wire your computer directly to your modem?
3) What Internet connection speed do you get when you wire your computer to the WRT54G2?
4) What Internet connection speed do you get through a wireless connection to the WRT54G2?
5) Is your computer's wireless adapter a wireless b? g? n?
There are many causes for poor wireless connections, and many solutions:

You should connect automatically (it can take up to 2 minutes). If you have trouble connecting, in the computer, temporarily turn off your computer software firewall, and see if that helps.
If the above does not fix your problem, download and install the latest driver for your wireless card.
Some users have reported improved wireless performance by switching from WEP to WPA encryption.
If you continue to have problems, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.

2007 Macbook Pro, Wireless connection slows to a crawl or drops out!

Hi all, I have recently started having problems with my 2007 15" 2.16ghz Macbook Pro and the wireless connection to my router.
Quite often it will say I am not connected to the network, the Airport symbol will fluctuate between full bars and no bars and when it does connect, the speed is awfully slow, it regularly hangs on a webpage for a few seconds before loading it up.
It is not the router as my Girlfriend has a white macbook and when I am experiencing problems she is not. Does anyone have any suggestions as to what may be the problem, is the wireless card on it's way out??
btw the airport details are:
Wireless Card Type: AirPort Extreme (0x168C, 0x87)
Wireless Card Locale: Worldwide
Wireless Card Firmware Version: 1.4.10.3
Current Wireless Network: SKY10597
Wireless Channel: 2
Thanks, Nick

You might try a different channel, but the iBook result belies there being a high probability of success using this approach. You could try a different browser. Does the problem also occur when you are very close to the WAP? Your card might be old enough to be malfunctioning. Given the recent experiences of others, I don't recommend doing any updates in trying to solve the problem. Have you done any Airport related updates lately?

Orange Livebox & MacBook Pro Slow wireless connection

Hello,
Looks like we are a lot experiencing a slow or sporadic wireless connection.
I have done all updates, the MBP finds the livebox and connect properly but I have a very slow connection.
Lan connection is working fine and quick.
Please could somebody help me, this is my first Mac, if there is any tips or tricks to get a normal wireless speed.
Cheers.

What kind of wireless router or access point are you using?
Are you getting full signal?
Is the wireless router or access point around anything with a lot of metal or..
since you said that when you connect to your modem via ethernet then you could have a problem with your wireless infrastructure... if you have tested your wireless network with another computer and it works fine or if you went somewhere that has a hot spot then you can determine if there is an issue with your home network or an issue with the wireless card in the laptop...

Very Slow Wireless Connection

try changing the MTU size on the router ui in the following order .... 1492 , 1452 , 1365 ... check whether it makes any difference ...

Has anybody solved the slow wireless connections speeds of the new Imacs

I have just purchased the new imac...and was made aware of the disastrous connections speeds using wireless.. Does anybody know if apple have come up with a solution...or are they just not dealing with the problem?

I am a brand new Mac user with a new 24 inch iMac purchase. Macs are supposed to be hassle free right? Right. No question I was about ready to throw it out the window because the wireless connection to the expensive AP base station was, oh, 100x slower than my Dell laptop side by side about 1 foot away. Nothing changed even if I connected directly to the AP using an ethernet cable. My connection consists of an Actiontec DSL gateway connected directly to my AP extreme that allows wireless to my PC laptop as well as my new iMac. Hours and hours go by until I find this help link on Mac Orchard Forums:

Slow wired and wireless connections on new Mac Pro

I have a new 6-core Mac Pro with 64GB RAM that I seem to be having major network issues with. When I restart or first switch the machine on it's fine but after a few minutes the network (web browsing) become painfully slow - when I run a speed test it come out at ~2Mbit/s. This is the same whether I connect on a wired or wireless connection. I've tried various connections including a complete bypass of my time capsule to a direct wall connection that should be giving 100Mbit/s. When i run a speed test on my iPhone connected to the time capsule via 5GHz I comfortably get >60MBit/s.
Is there a bug in the latest OS 10.9.4 my MBAir also seems to require a lot of restarting to keep up even basic web browsing???

Your Macs are always looking for a better connection. To that end, they are evaluating every possible way to get to the Internet.
It is very important that you limit those choices to only the ones you actually want to connect to, and indicate that the other are "off the list", literally.
For example, to test your wired network connection, Ethernet must be at the top of the list AND WiFI must be OFF. (Otherwise, your Mac will be checking WiFi to see if it seems to be getting a better connection over WiFi. In the screenshot below, Ethernet is at the top of the list, so it is likely to be used, but since WiFi is still ON, it may be used instead.
To check YOUR WiFi connection (and not your neighbors' connections), you need to BOTH check that the "ask to Join new Networks" box is checked:

Wireless Internet connection very slow

The wireless connection has gotten very slow. I have restarted the modem but that has not improved the connection. I am about to restart the TC and see if that improves the connection. What is the best way to shut the TC down and restart it? The only way I know is to unplug for 15 seconds and then put the plug back in.
Thanks

Try the following ...
o Power-down the modem, Time Capsule (TC), and computer(s); wait at least 10-15 minutes. Order is not critical.
o Power-on the modem; wait at least 10-15 minutes.
o Plug-in the TC; wait at least 5-10 minutes.
o Power-on the computer(s).
