Intermittent Speed Drops On Downloads?

Jun 24, 2011

I have two computers, both of them running Windows 7. One of them has been experiencing an odd problem for about six months now, and now that school is out I have time to mess with it. When I try to do certain things, the download speed periodically drops to zero. Specifically, I've noticed it when using Firefox and Steam, but also for IE and a few other browsers I installed for the sake of testing. I know I'm not *losing* connectivity, because everything that isn't specifically downloading a file works fine. Skype calls work fine, Utorrent streams at a steady rate, but for some reason Steam and Firefox have speed graphs that look like the heart rate monitor of someone with a very weak pulse. It starts off strong, a nice solid 1 MB per second, and then after 10-30 seconds it'll slowly decline to 0, and sit there for anywhere from 10 seconds to half an hour before picking up to full speed again. I've tried reinstalling drivers, I've tried buying a new network card, I've tried running antivirus scans, and I've tried uninstalling my antiviruses. The only thing that works for sure is putting it into safe mode. In safe mode, the downloads proceed smoothly. I tried making a list of everything that ran in safe mode, and then rebooted into normal mode and closed each nonessential process and service, but that didn't work either.

D-Link DAP-1522 :: A1 In Bridge Mode Intermittent Wireless Connection Drops?

Apr 21, 2013

I have a brand new DAP-1522 A1 connected to an 802.11n wireless LAN in bridge mode. Running in the 2.4GHz band with WPK-2 and AES security/encryption.Everything runs fine 99% of the time, but once a day or so the wireless LAN connection on the DAP-1522 drops and then takes about two minutes to re-connect.  It re-connects and then everything is fine for a day or so until the next dropped wireless connection episode on the DAP-1522.  I know my 802.11n wireless network is 100% fine as during the dropped connection to the DAP-1522 I can connect directly to the 802.11n wireless network (running from my gateway/router) using my other computer, no issues.I've seen some posts on this forum that the A1 version of the DAP-1522 hardware is not 100% compatible with the 802.11n network standard and there will be intermittent wireless drops.  If this is true, it's just insane.  All I can say is I can't believe DLink would allow a product to be sold that won't work properly on 802.11n networks.I check the logs each time I see the dropped wireless connection and all that shows is the following.1) Negotiating connection   2) 4-way handshake success [mac address]There's no message in the logs about why the wireless connection dropped, but I assume it has something to do with re-newing a key for the wireless network as the successful key renewal messages are the only other messages in the log.  When the wireless network dropped I don't see the successful key renewal message at the time I should see it.I thought this DAP-1522 would take 15 minutes to configure in bridge mode and then I'd forget about it.  Spend too much time on this already, so a bit disappointed with this DAP-1522 and DLink tech support....though when it's connected to the 802.11n wireless LAN it works fine.

We are facing issue related to STP.I am getting MAC FLAP error on Cisco 4510 switch. The effect on network is intermittent Pkt drops in the network. When I checked the specific Ip address I am getting the same with two different.

Uploading Speed So Much Slower Than Downloads?

I was wondering why are upload speeds so much slower then download speeds with residential IPS. I know downloading is alot more common then uploading something. Does it cost more or something, for the ISP to send information out.

Intermittent Internet Speed Slow Downs With A TP Link Usb Adapter?

Mar 22, 2012

I have recently bought a TP Link wireless usb adapter (TL-WN727N). Initially I had some issues with drivers but solved that and my internet was working perfectly for around 2 days. However recently the internet speed has dropped down to extremely low speed periodically for no apparent reason. I can be downloading something at around 700kBps one moment then only have 100B/s the next. [CODE]

Linksys Wireless Router :: WRT54G Slows Down Speed And Makes Many Downloads Fail

Jul 25, 2011

I can't get utube videos when I'm going through the router.  I can get them if I'm on the modem only.  The same applies to long PDFs, software updates, long virus definition updates, videos in general and graphics heavy websites.  It just slows down eventually to a standstill and the download fails.  As stated when the router is not connected the above items pop up or download reasonably quickly through the modem.  We have moderate speed DSL.

Cisco Switches :: SG300-28P (SRW2024-K9) In L3 Mode - Intermittent Loss Of Speed

Jan 24, 2011

Every "once in a while" (about a week with my network load), the SG300 crawls to an almost standstill of all IPv4 activity (haven't got IPv6 enabled here yet, so I can't comment wether this applies to IPv6 as well). It seems pure L2 transmissions is not affected, but L3 definitely is (down to 20mbit as opposed to the 600+ rate I usually get).
 
Soft-rebooting the switch (via the webgui) useful, and the intervals of the crashes seem related to total bytes transmitted, not time. I have jumbo frames enabled, and disabled flow control on on the switch and all hosts.
 
Firmware Version is 1.0.0.27, md5 1987292110f5657e74308dde30c03dc4 Boot Version is 1.0.0.4 md5 4c9a0b6a9f1346736646d08ab94ae2ac

Speed Drops When Using Router?

Feb 23, 2011

i recently upgraded my road runner cable from 1.5Mbps to 10Mbps.I checked my speed on speedtest.net and my speed was an astonishing 20Mbps.the problem occurred when i hooked up my linksys 4 port model nr041 router so my bro can also use his laptop. i checked on speedtest.net with the router hooked up, without us using anything, and the speed dropped to 6-10Mbps. I don't know why the speed dropped so much. We weren't messing around with anything and wasn't using the internet.About 3 hours later after my bro was done using the laptop I disconnected the router and plugged the modem straight into my pc and the speed shot back up to 20Mbps on speedtest.net.

DSL Speed Unsteady / Drops Constantly

Mar 31, 2011

so upstairs is where my 2wire router is, with a steady 54 mbps signal speed and a excellent signal strength for any computer upstairs, BUT any computer downstairs will have the signal strength goes from 1 through 24 mbps alot.Now, I do have other computers connected to the router, none are taking up the speed, and all have the same signal strength. All of these computers are upstairs as well.I know for a fact it isn't the computer, since when my computer was upstairs it would work fine, but with everything exactly the same it'll be horrible downstairs.Only things I have thought of might be interference... but have zero idea how to find what would be causing the interference if any exist.

ADSL Speed Drops Down With Router

Dec 27, 2011

[code] My connection is ADSL with 2Mbps broadband. Using speedtest.net for testing the speed I got almost 2Mbps, that is ok, but this is connected directly to the modem. The problem is when I use the router, when I connect it the speed downs onward until it achieve a stable value of 512kbps, that is 4 times less than my contracted speed. I have tried with four different D-Link routers (DIR-280, DIR-600, DIR-600 N150, DIR-615), four ones give the same problem.D-Link tech support people don't have idea about what is happening just like tech support people from my Internet provider. I think the problem is not the modem because I get 2Mbps from it connected directly (without the router).I do the speed test in an interval of 3 minutes between each test, with just one device connected and only doing the speed test, all programs that use Internet access are closed.

Always is the same, after a time the speed drops down, from 2Mbps until 512kbps. The router has the QoS disabled, I have tried changing the MTU value, I have tried some values 1492 (this is the official from the Internet provider), also I have tried some lower numbers 1400, 1200 but the result is the same. The router has as security only wpa2 and it has a static public IP, the modem is configured as bridge. I have also tried unplugging the phones, connected to the splitter, keeping away the wireless phones, moving away the router from the modem for electronic interference, modifying the WAN speed from auto to 10 and 100, I have disabled the firewall, change the channels and power TX. I do the speed tests using the wireless and wired interfaces.

D-Link DIR-825 :: Router Drops Internet Speed?

Jul 23, 2009

I have had the DIR-825 since the beginning of the year connected to AT&T DSL Internet 3GB. I just upgraded to their 6GB download speed and didn't see any change in speed and suddenly I couldn't view my SlingBox anymore outside the house. I connected one computer directly to the modem, ran the AT&T speed test and got >5GB download and @700 upload. Wired via 1GB network back to the router, ran the speed test and it dropped to @4GB download and 120 upload.

I called AT&T, they checked everything, and said there was nothing wrong. I then spent almost an hour on the phone with D-Link including getting passed to 3rd level support. I knew something was wrong when the guy told me that since it was only a 1GB router, I shouldn't expect to get faster than 1GB Internet download.

The router is still running the 1.00 firmware and these are the changes they made me try so it's still sitting at these settings:

- Change the WAN from Auto 10/100 to 100 only.

- Change MTU to 1482 in my PPPoE settings

- Change Firewall Settings to turn SPI off. He said the router is still providing a firewall though.

He wanted me to download the 1.01 firmware but I balked and he said it probably wouldn't do any good. It ended with him wanting me to call AT&T back and set the modem to bridge mode. I then need to call them back and set the PPPoE again. This 3rd level support guy was very rude and am hoping to avoid calling them again.

Before I go through the hassle of calling AT&T and trying this bridge mode, or has the Elite 6GB service from AT&T and are having it work correctly.

Cisco WAN :: 871W Significantly Drops Speed On WAN Int When ZBF Is On

Jan 16, 2011

As soon as I add the interfaces of the router to security zones it significantly drops speed on WAN interface, below 1  Mbs. I noted this because I wasn't able to watch youtube. Moreover the bandwidth test from speedtest.net hangs and doesn't come to a result. Here below is the diagnostic example while doing that test. The question is what is going on? I have two iPhones and three computers in my network, that's it. My ISP bandwidth is 10 Mbs, so is this the router hardware limitations, or kind of malfunction or some misconfiguration down here? What could be done here ?

D-Link DIR-615 :: Wireless Speed Drops From 300Mbps To 130Mbps?

Feb 20, 2013

I have a issue, my DIR-615 V.E3 has been working good.  I have multiple computers connected and all get between 280 and 300Mbps.  But then after a few hours the speeds drop to 130Mbps on all computers.  After I reset the router the speed returns to 300Mbps.  I have it set up to run on N speed only so g devices are not connecting.

Linksys Wired Router :: RV082 - Speed Drops To Between 2-3mb / Sec

Oct 25, 2007

Networking isn't my strongest computer subject area, but I know I'm having a performance problem with my RV082 router. When I direct connect my PC to my cable modem, I can get very near the 7mb/sec rate advertised by my ISP. When I connect the modem to this router, then connect to the pc to the router, the speed drops to between 2-3mb/sec. All tests performed several time using dslreport.com speed test website. The result is very repeatable, so I figure it has to be some delay introduced by the router. I can't see to find any place in the router configuration to do performance tuning. I'm not using any firewall rules except for the default rules. Why I'm seeing a greater than 50% decrease in internet throughput using this router?

Dell :: XPS 15 L521X Wi-Fi Signal Speed Drops Significantly

Jul 24, 2012

I got my Brand new xps 15 yesterday, It works fine, looks great, I'm overall satisfied with it. (even though it gets warm all the time) 

Problem is, the WIFI doesn't work well at all, I'm 2 meters from my box right now, And I'm not experiencing any problems, but as soon as I get upstairs in my bedroom, my signal speed drops significantly, I can't even load a you tube video, I was downloading a game from steam yesterday, and the dl speed dropped to 6mb/s!! That's awful, If this problem can't be fixed, I'll be returning mine, and won't buy any other Dell product, I don't see how a laptop that pricey can have that kind of problems. ( because I heard I wasn't the only one, a lot of people have the same problem).

Download Speed Drops After A Few Minutes Of Resetting Network Adapter?

Aug 2, 2012

I am having an issue with my network connection. I have tested the connection itself and it's not a problem on my ISP's end or the connection itself, but seems to be caused by hardware/software errors originating from the computer. It almost appears as if the connection is being capped or the like, because the signal is very strong when I connect to the internet at first, then after a few moments drops (consistently every time I try reconnecting) to an unacceptably low signal level.

Linksys Cable / DSL :: Wag120n Internet Speed Drops With Time

Aug 10, 2012

I am using linksys cisco wag120n adsl2 modem router.When I start the router the internet speed seems great but after some time the speed drops miserably. When I again restart the router the speed seems great for few mins but again drops after sometime.It happens in both LAN and wireless mode.The firmware version of the router is 1.00.16
 
I was going through the problems posted by some other user but observed that cisco people are not heraing to them.Seems made a mistake by associating with cisco product.This is the worst router I have ever used.The wireless also gets disconnected abruptly.Next time I'll avoid cisco.Cisco is all about stone age products and zero customer care.

Linksys Wireless Router :: E3200 - Internet Speed Drops?

Jul 17, 2012

We recently purchased a Linksys E3200 router, because our old router didn't take advantage of our internet speed. The router works fine, though the internet speeds again isn't as much as expected.
 
With a wired connection, we only get 80 Mbit/s of our full 120 Mbit/s, according to Speedtest.net. The Cisco Connect built-in speed test is even worse; only 40 Mbit/s. When we directly plug the computer into the modem, we get the full 120 Mbit/s, which indicates that the modem does have the connection speed. The router just doesn't give it to the computers attached.
 
I don't know about my wireless speed, as my wireless card in the laptop clearly is the bottleneck (it can only connect at 65 Mbit/s). Atheros AR9285 ftw.
 
We tried different cables, the one included with the router gives the same speed.

Linksys Wireless Router :: Speed Drops When Connected Through E3200

Mar 7, 2012

Got a Linksys E3200, and a gigabit card, even two, Realtec and Intel, have a connection ggbit. If the power cord plug directly into netcard, all at great, the tracker up to 80 MB per second, shakes on speedtest.net, shows 780 240 + Mbps. When i connect my inet through the router, the speed drops to 12 MB(100 Mbit) and speedtest the same, but in the the web interface in the statistics shows that everything is connected to a gigabit.

Plus, when I ping my ISP's website (ip -t ) and assume [URL] click on the test, the router with 1ms pings are beginning to rise to 30 ms, and when it is directly in netcard, it stable 1ms.... When through the router, torrent shake it just do up to 100ms jumps. I have all the settings , and set up his hands, and a manager, all for nothing. It started five days ago, before that everything was ok. Can a router burn? Rather it gigabit controller?

Linksys E1000 - Wireless Speed Drops To Nothing When Main PC Is Off With Great Signal

Jun 22, 2012

I have a Linksys E1000 running on the latest firmware available from the Cisco website. When my main PC (Windows 7 64Bit SP1) which is connected with a ethernet cable is running the wireless speed is great for all my connected devices. (Android/Apple phones, tablets, family PC, etc). But when I shut down my main PC the wireless speed drops to the point where it can take 3-5 mins for google.com to load up. The wireless connection is still showing as strong, just the speed isn't there anymore. If I were to turn my PC back on, everything will load up almost instantly and be back to normal. I've tried reinstalling the router, resetting it all back to default settings and re configuring it but I've had no luck in solving this.

Linksys Wireless Router :: E1000 Speed Drops Down Significantly To 8 MBPS

Aug 11, 2011

I purchased a new router - cisco e1000. Currently, i have 2 laptops wirelessly connected to this router. When i do a broadband speed test, the speed drops down significantly to 8MBPS while if i connect it to the cable modem  directly (wired) i.e., without router, i'm getting 15 MBPS download speed. I did a couple of times this speed check and the results are same. I tried changing the advanced settings in the router (which was specified in one of the post in this forum) but no luck. Is it that i need to buy e4200 to match the wired speed of 15 MBPS or what other things I can do to get the same speed of my cable modem (provided by my ISP)?

Linksys Wireless Router :: E4200v1 With QoS Turned On Upload Speed Drops To 300k

Dec 21, 2011

I have four E4200's doing the same. I have FiOS 15M download and 5M upload. As soon as QoS is turned on the upload speed drops down to usually 300k and it never exceeds 1M.At the same time any VPN connection gets dropped often.I also configured one E4200v1 as router and the second E4200v1 as Access Point (HDCP off) hardwired to the first one.Any VPN connection gets dropped when changing location. I.e. if VPN was established with the router, the connection gets dropped when in the location where AP is -- and the other way around too. There is no coverage gap between the two locations, to the contrary - they do overlap heavily.On Dec 21, 2011 the level 2 Linksys/Cisco people advised that they will forward the two issues to engineering and that resolution will be within 24-48 hours.
