Internet speed drops 85% when routed through WRT160NL

I have a WRT160NL, and it decreases my internet speed from 3700kbps down to 550kbps when I route through it.
My ADSL modem is connected via ethernet cable to the WRT160NL, then I have an ethernet cable from port#1 of the WRT160NL to my desktop computer. With this connection, I get a download of about 550kbps.
When I route directly from my ADSL modem to my desktop (bypassing the WRT160NL) my download speed is 3700kbps. I've checked all cables and connections. What is causing the speed to drop by 85%?
thanks,

Go to Solution.

As you are facing the problem on your Hardwired computer, then you change the settings on your Router... Once you login to the Router setup page.. Below the Setup you will find MTU size which will be set to AUTO so you need to change it to Manual and change the Size from 1500 to 1365 and click on Save Settings..... Then click on the Security tab and Disable "SPI Firewall" and Uncheck "Filter Anonymous Internet Requests" and click on Save Settings...
Now you need to power cycle your Network... Unplug the Power from the Router and Modem, Wait for 30seconds and then plug the Power to the Modem, Once all the Lights are lid on the Modem then Plug the Power to the Linksys Router...
Now you can check the Speed, what the speed you are getting it on your Computer....
If you still face the same problem then i think you need to upgrade the firmware of your Router.. Go to website linksysbycisco.com/downloads.........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop....
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Internet speed suddenly and drastically reduced through TWO different routers (EA6500 & E2500)

I'm definitely experiencing a bizarre problem at the moment with internet speed (both wired and wireless) through my EA6500 which began suddenly two days ago. The modem directly into the computer continues to yield the normal speeds (about 3.5 Mbps down and 1 up) each time I connect it directly, but putting the router into the equation cuts it to around 0.5 Mbps down and 0.05 up, though the speeds do tend to vary quite a bit. I just assumed that the router was defective, so I grabbed my older and perfectly operational E2500 to put back in its place, but the results were exactly the same. I went through all of the troubleshooting with the cable company up through the modem, and again, the modem continues to deliver the normal speeds directly to the PC. I also swapped all of the network cables around to verify that they're all good, so that's not an issue either, and the firmware on both routers is current. While certainly possible, I have a hard time believing that both routers just happen to be bad at the same time, and I haven't made any changes in the last few days to the network configuration, settings or even the software and setings on my PC. This truly is a baffling problem, and I would greatly appreciate any thoughts on the matter. Thanks.

That interesting the MTU being 1280. That is the typical MTU of an IPv6 tunnel. Is IPv6 enabled on the router? Maybe your ISP has implemented IPv6.
Please remember to Kudo those that help you.

Internet speed slows down when connected via airport express

Internet speed slows down when connecting via airport express. When connecting directly via the timecapsulethe internet speed is ok, when connecting via the airport express the speed slows down.What can I do to change that? Any suggestions?

Turn off the AirPort Express completely as a test, and move your computer very close to the location of the Express.
As I said before, the Express can only extend the bandwidth (speed) that it receives from the Time Capsule, so the speed that you see there with the Express powered off will be the fastest speed of which the Express is capable.
The Express will make the signal go further when it extends....but it will not make the signal go faster.
A good location for a device that extends wirelessly is a point that is about half the distance from the Time Capsule and the general area that needs more wireless coverage.
If you locate the AirPort Express too far from the Time Capsule or there are more than a couple of walls in the signal path, the signal will be very slow by the time that it reaches the Express....and the Express simply extends a signal that has already slowed down significantly.
If you already have the Express located about half the distance between the Time Capsule and general area that needs more wireless coverage, how many walls, ceilings or other obstructions are there in the signal path between the Time Capsule, the AirPort Express and the area that needs more coverage?
Often, due to obstructions, it is just not possible to achieve good performance when you try to extend a network wirelessly. The solution is connect the AirPort Express to the Time Capsule using a wired Ethernet connection.
There is virtually no signal loss with this type of connection, so the Express can be located exactly where it is needed and it will produce a much faster wireless signal in this type of setup.

WRT330N slow cable internet, speed drops significantly

I have been using a new WRT330N gaming router with firmware 1.00.4 and one day the connection speed drops to 10kb/s download speeds from every connected device(xbox360, vista, xp). I turned off the WRT330N router and connected my old WRT54G speedbooster router and my connection is back to 800kb/s. I did a factory restore to the 330N but after about 40 minutes the speed drops to 10kb/s again... I can't seem to figure out what is causing this to happen when my other router works just fine.

If possible try upgrading the firmware of the router keep on holding tightly the reset button in such a way that power light is blinking on the router & then do a complete network power cycle i.e., unplug the power cables from the modem & from the router & then plug in the power cable to the modem first once all the lights are solid green you could plug in the power cable to the router & check out it will definately work!!
Also, you need to do the advanced wireless settings such as Radio Band Frequency to 50,Frag thres=2306 & Rts thres=2307 & then uncheck a Block Anonymous Internet Requests & it will definately work!!!

Slow internet speed/ dropping internet

I am on the Bt Ifinity 2, last year at summer time (8/10/2014) every thing was fine 59 mb/s down 19.55 mb/s up. bettween then and the 11/11/2014 speeds fell to 13.8mb/s down 10.24mb/s up. (mediafire link for page download for internet speeds http://www.mediafire.com/download/24vs7ra8pyl09qc/bt+stats.rar )
during this time untill the 19/11/2014 the internet would just drop randomly, 3,5,6 times a day commonly (not shown on the graph for due to no internet). the internet droped and the router was not connected to the internet shown by the ui in 192.168.1.254. internet speed is lower then the what was on the speed test so would strugle to steam youtube videos.
i thought that this was a throtling thing origionaly, but i tryed off peak time 1-4 AM the connection dropped slow speeds
we called a bt enginer out for the 19/11/2014 we a router replacement and some line was changed there was no internet dropping untill reasontly speeds increased slightly.
8/1/2015 I was downloading addons for battlefeild on my playstaion when the internet started dropping again the internet speed on speedtest.net showed a resonable speed of 30mb/s down 1.97mb/s up which should be fine for content consumption. well thats what i thought, youtube videos in 240p would not play.
in my oppinion it looks like bt has being throtiling my traffic, but i know bt only "manages p2p taffic during peak times"
any one know whats wrong, by the way there is know other users on the network at the time of the speed tests
Thanks for reading

Next time your speeds are bad, or right now if they are now, please try this:
In order to rule out the Homehub as potentially being the device responsible for your speed loss, you can connect the Openreach modem directly to the PC and see if the speed improves.
To do that follow these steps:
Step 1: Remove the homehub from the modem cable
Step2: Connect your pc/laptop to the modem via the cable instead
Step3: Open network and sharing centre on windows and click set up a new connection or network
Step4: Connect to the internet then click make a new connection Broadband PPPoE
Step5: Username [email protected] and the password as BT
Step6: connect, If it doesn't,keep pressing try again until it does.
However, please note that this will stop any other access apart from the PC

Internet speed dropped to dial-up speed!

*(It took me about 15mins to get to this page)*
There seems to be something wrong with my Mac when i opened it up today; the internet speed has dropped right down to below dial up speed, yet all the other computers in the house are running fine at broadband speed.
Hope you can help!
Thankyou very much in advance!

The following usually works on both Tiger and Leopard:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
If not, MacFixit have published a very detailed (very!) article on speeding up a slow Safari, here:
http://www.macfixit.com/article.php?story=20070416000657464
Many, including me, have also followed the advice given by others here to add DNS codes to their Network Settings, with good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.220
208.67.220.222
Click on Apply Now and close the window.
Restart Safari, and repair permissions.

Internet Speeds drop drastically on all devices when one device is streaming media

As described in the title, when one of the devices on my home network begins streaming media, speeds are drastically reduced across all of the devices.
Comcast has always stated that you can do whatever you want on any device without it affecting the other devices in your home.... but streaming on one device brings all the other devices in my home to a crawl.
This was always the one thing that set Comcast apart from AT&T in my opinion, and if this is no longer the case, then Comcast can say goodbye to my subscription.
I am paying the extra $10/mo for Blast internet also.... and this is completely unacceptable.

exactly the same experience here, installed the xfinity app on an ipad, and when someone is streaming to said IPAD from the xfinity app, the other wireless connections in the house become practically unusable. Even wired connections to the modem/router itself start lagging out. Even something simple as looking at a forum and making a post is almost impossible if someone is streaming a t.v. show. Clearly not what is advertised. Really dissappointed.

Internet speed dropped from 2Mbps to 135Kbps for p...

Hi,
Until last week i had 2Mbps internet which was fine and stable, then it suddenly dropped to 135K.
I did not change anything on my network to caus this
I have tried a different router/cables/microfilters and virus checked with avira and malwarebytes none of which did anything so i am convinced it is an external problem.
I called india who reckoned i had 6Meg available.
Please can you find out if anything has changed somewhere else in your network or with my account that would cause this.
here is the speedtest results
Download speedachieved during the test was - 114 Kbps
For your connection, the acceptable range of speeds is 50-250 Kbps.

Hi Welcome Your IP Profile has dropped because of a noise issue on your line causing the exchange equipment to see your line as unstable normally the profile will rise within a period of 3/5 days providing there are no restarts on your hub.
Some exchanges are now using a new profiling system that gives 88.2% of your connection speed the profile change on these exchanges is immediate at the new connection speed all you can do is wait while the exchange equipment restores your profile

Help! Extremely slow Internet speed using Linksys WRT54G router

I have an eMac running OS 10.3.9 and wired to a Linksys WRT54G router using ethernet cable. I have to use this router for my work PC. I'm also using WildBlue satellite internet. The problem is, I'm getting about 1.5 Mbps on my PC, but less than 33 Kbps on my eMac. It was running faster before using dial-up. I've called WildBlue and Linksys tech support, and they can't help. Can anyone help?
By the way, my son is using his iBook on the same router, only wireless, and he's happy with the speed he's getting compared to dial-up.
Thanks,
Eric

1400 kbps is a lot nicer than 33 kbps, isn't it? You can possiblly tweak it a little more --- I know I've seen a MTU of 1460 mentioned --- since you can also revert back to the 1400 MTU setting you found.
(Broadband Optimizer is in one sense a nice GUI to the terminal commnads you found and used.)
One more thing to be aware of, satellite internet is subject to longer latency times than cable or DSL, due to the unavoidable geometry of bouncing data packets off a satellite in orbit. That could be an issue if you ever want to play real-time online multiplayer adventure type games. It shouldn't be an issue for being able to grab OS updates in minutes instead of hours, through. Enjoy your broadband access!

EA6700 Internet speed drops

Hi,
I recently purchased a brand new EA6700.
Installed it prperly and started surfing from several devices such as Laptop, ipad and iphone.
Though the new router slows download speed from 15Mbps to approx. 2-5Mbps.
My network looks like this:
ADSL ROUTER-MODEM Siemens SL2-141 and now EA6700 connected to it using CAT5e(from SL2 LAN port to EA6700's internet port)
After reading almost everything written here, I have done several tweaks yet no success.
Switched ports at the SL2 ROUTER-MODEM.
Disabled media prioritization at EA6700.
Disabled PPPoE at the SL2 and set it at the EA6700 by that changing from the DHCP and the double NAT situation I had before.
Reset the EA6700 to factory default and reinstall it manually.
I also wish to inform you that my router's firmware is up to date (1.1.38.149770).
There is no difference beetween a wired speed test and a wireless one.
The only tweak that I can recall that helped just a bit was setting the EA6700 at Bridge mode but still it had not solved the problem.
I'm pretty sure the problam is not the SL2-141 or its connection to the EA6700 since before that router I had an Edimax router which was connected the same way and preformed perfectly with the SL2-141 for several years.
I have no idea how to proceed from this spot, ANY HELP WILL BE APPRECIATED!

Hi,
When you set the PPPoE dialer on the EA6700, have you tried setting up the MTU as well? Based on this link, MTU must be 1492 (or lower) when using PPPoE connectivity. Check the following links on finding your optimum MTU setting:
How do I optimize my MTU and RWIN settings?
How do I find my optimum MTU setting?
Hope this helps.
If everyone needs to believe in something, I believe I'll have another beer..

Internet Connection Drop Outs when remote administ...

I did not want to trouble anyone here if I thought it unnecessary but now I feel that I do need some assistance so this warrants opening a new thread.
BT Infinity Option 2 customer with BT HH 4 and its separate modem - not hacked so cannot read any useful information or login to see what is going on and both BT and the manufacturer long ago removed the open source code of the modem.
I am quite confident now that these disconnections happen when a remote server/attacker attempts to gain access to my network. These can be from China, Iran and other places too. Sometimes Ministry of Defence? I don't know why I get these connection attempts and most of the time I see BT HH 4 does block these so why I get disconnected I have no idea?
I made a post in an old thread before opening this thread and said it was due to firmware upgrade but I misread the date! It was not updated since the 8th of May I think. These disconnections have been happening only this past 4-7 days with the most 4 days with intensity greater than the 3 before. I am not 100% certain it is caused by the remote administration that is blocked.
What happens when this takes place is the BT servers are then unreachable sometimes and I cannot regain a connection for up to 3 hours at a time, usually it is 5-10 mins max though. Without looking at my event log, any ideas?
I want to get different gear now and never wanted to use BT equipment anyway because I want greater control and options to configure. I would like to go with DD-WRT or OpenWRT Router with Integrated VDSL v2 modem. Anyone here that may suggest one that supports either of these open firmwares? Not so much the concern to prevent any security holes or backdoors but just as much if not more for versatility and configuration and just having control over my network. being able to do upgrades when I want and not when my ISP decides needs doing. And before you say BT do not have backdoors then why would they admit they can remote login to devices and storage contents with their pwerline adapters even. I remember reading a news article quoting BT as admiting this. Anyway, that is not my main concern here, as much as privacy and security is not a crime it is rather rare online. First I need to get to the root cause of this.
BT HH 4 is not reporting any DDOS attacks and even if it were I would not expect to experience any disconnection. I used to get tons of floods from DDOS attacks years ago when using Netgear routers and never exeprienced any downtime, but that was with another ISP. I don't detect any malware or anything like that and rarely download anything on this machine, I know web browsing can infect a system but I don't think that is it.
I want to go back to how I used to do things. Any help with this is appreciated. I will need to get my router login details because I was never given those when I singed up with BT Infinity Option 2. I don't even know what my BT email is but do believe there is a way to recover that under my account. **In the past we have had intermittent connection drops and loss of sync but this is not the same right now.
Edit:
** Just to clarify that was before we upgraded to BT Infinity Opt 2. This is the first time any probs with this service since upgrade and that must be about 6 months or more now.

When running BT HH diagnostic it printed out that the username for login had changed and needed resetting or for me to enter my own in that I was NOT given! Anyway, when going to select manual reset it had not changed from default at all so I think this is just some default BT diagnostic that is false. I realise that other BT customers are affected by this with the BT HH5 but mine is HH4...my posting probably isn't as clear right now as I have not slept as much past few nights trying to figure this out. This is happening at different times of the day but more often during early hours.
So I am getting these WGET TLS error(s)
How do I enter in log excerpt from BT HH? Forums says my post exceeds 20K chars...

Sudden internet speed drop

I am a BT user for a long time now and since I had very few problems with the internet. Started last week, my and other people's internet(some of my friends also have problems with the internet just like me) in my area (aberdeen, tillydrone) became very slow. For example my speed is: 300 kbps download speed and 600 kbps upload. I am suprised that my upload speed is more. The thing I am asking is that while I pay for an 8 Mbit internet why do I get 300 kbps right now?
I have cheked the connections got new cables for everything it is still the same, even tested the router if is has any faults but it doesnt have any. I dont know if there is any maintenance in my area because I havent recieved a paper saying anything about any problems at that area. Please help! I am out of options and I am getting tired with this incredible slow internet.
Thank you

Internet speed drop to 100mbps from 1gbps

my internet was Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)

The speed is dependent on the slowest
network port. Are both ports gigabit? for some adapters you can set it to 100 mbps manually.

Internet speed drops 85% when routed through WRT160NL
