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).

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 ?

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)?

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.

I let him take control of the system, he ran [URL] with me 6 feet from router, and then again 30 feet. Huge difference in speed, approximately 10x slower at 30 feet. He initially stated the problem was with the antenna connection and offered to send a tech to replace the antenna, which requires a display replacement as well. I was skeptical so pressed him to verify that this was a known solution since there were so many complaints. He was absolutely certain this was the issue, but put me on hold to double check. He came back and stated they needed to replace the wi-fi card from the Dell 1901 to Intel 2230 along with the antenna. As a former antenna engineer, I suspect the problem is the design of the antenna and/or its location, and not the drivers or wi-fi card.

My new computer was delivered December 21, 2012. Imagine my surprise that I can't connect to my wireless connection unless I am less than 10 feet away from the AT& T wireless router. There are 3 computers 1 floor up and 30 feet away that can connect, so I know it isn't that the signal isn't strong enough. My Inspiron 9300 that I have had since 2005 can connect and I am using it right now. Here's my specifics.
17r SE 7720
Windows 8
1 T hard drive
8 G RAM
32 G SATA Drive
Inter N-2230
AT&T internet wireless router.
The new computer will hook up when extremely close to the router but it does lose the signal occasionally even though I am only 10 feet away.

Ive set my laptop to stay on when the lid is closed. Now when i do close the lid, the touchpad reacts to the screen and starts doing all sorts of crazy things, zooming in and out, moving the taskbar around, opening things and deleting things.Ive resorted having to place a cloths or kleenex folded in half over the touchpad when i close the lid. ive also disabled the touch and used a mouse and no problems. I have updated the drivers and dell toucpad, ive even uninstalled everything and installed the synaptic drivers and touchpad software.. Yet another problem with the l521x.How can i fix this? maybe the touchpad is defective and has to be replaced?

I recently got a new modem/router device from my ISP and its wifi is fairly weak (no external antennas) especially in my basement. Since wifi is no longer an option and I only have one ethernet connection to my basement I was thinking of using my old router to distribute the one ethernet connection to multiple devices. Connecting my one ethernet connection to the old router, and its port#1 to my PC in the basement works without any meddling, but the speed has taken a significant hit. Before the second router I was getting ~30-40Mbps from my ISP. With the second router it is reduced to ~10-20Mbps. Both routers I assume are capable of at least 100Mbps (probably even 1Gbps?). The older router is a Linksys WRT54G which can do 54Mbps wirelessly so I assume it can exceed 10-20 wired.I tried giving the second router a static IP with DHCP off, but it did not seem to make a difference. I don't know if I set it up correctly, however. The modem/router uses 192.168.0.xxx while the second uses 192. 168. 1.xxx so I do not think there is any conflicts in the DHCP.

At the recommendation of a tech, I ran a speed test (speedtest.net) on my system with my N600 in place. The upload speeds averaged out to 0.21mbps. I took the router out of the system and the speed climbed to an average of 0.37. What is the problem with the router and what need I do to boost the upload speed with it in place?

I currently live in a fairly-large apartment in Downtown San Francisco and as you can probably imagine, I have ALOT of interference with nearby residential and business wifi's, microwave's, cell-phones and all that jazz.
I currently have the ATT Elite DSL package, which is I believe the 6MBPS(?) package? Anyway, it's the $40 package and I want to say it's either the second or third up from the basic 19.95/month subscription. Here's my problem: ever since I moved into this building, I get signal drops on my ATT all the time--like at least once an hour if not more often. I had a technician check the wiring and he even replaced the router box (they always do) in hopes of improving the situation but so far, no dice.
I have tried switching to different channels after using scanning to see what channels other internet users nearby were using, but I did not see any improvement.The best solution I've been able to come up with is to set my router to be on 802.11B only. For the most part,I have not disconnected but I do feel a certain amount of slow-down or lag compared to my 802.11G settings.Now,I might be paranoid but it certainly does take a good amount of time longer to load up pages and such as compared to previously.The tech suggested I look towards getting an 802.11A/N router, but alas ATT does not support routers of that caliber...not sure why. It's been years and they're still stuck with the 2Wire 2701HG-B model for DSL.

At 9:15 each night my DLINK router drops the signal.I've tried to unplug it but that doesn't work but it is working again each morning. I can plug directly into the cable modem and it works so I assume it is fine.Is there a time setting on the router?

My WRT120N drops signal to Laptop occasionally and I do not understand why. I tried to update the firmware, version 1.0 to 1.0.04, is that a newer version? My next step is to try to update the drivers in the laptop. The dropped signal seems random and only happens with the laptop. Other devices connected work fine.

I have the following problem:
Adapter: WMP600N
Router: E2000 (N-only)
OS: Windows 7 X64
When I'm not connected to my wireless network, the signal strength is 4 bars (out of 5)Once connected, it drops to 2 bars. Speed is 39 Mbps. Why?I have updated the drivers (strangly, it says the drivers are from Ralink Technology. Corp, version 3.00.00.0041 built by: WinDDK)

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.

I recently installed a Cisco X2000. Several PCs running Windows XP Pro connect wirelessly. Also, we have an Android device and iPhone connected to the wireless network. We have a network printer and network drive connected via wires to the router. Most of the time the router and cable modem features work well. However, every so often all devices lose wireless signal simultaneously. It is not possible to reconnect to the X2000 unless I unplug the X2000 and plug it back in. After this reboot, we can connect again. Obviously, this is quite frustrating. By the way, we get acceptable signal strength after the X2000 locks out however none of the devices (computers or phones) are able to connect.

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.

I have tested internet speed on Ethernet (~20 Mbps), but when I'm connected via wifi network, it drops down to ~11 ? The speed is same on all wireless devices even when I sitting next to the wifi router.

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.

[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.

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.

I have my DIR-655 router set up on the first floor because my son's tricked out gaming rig is in the basement while our office is on the 2nd floor. On the router, I tweaked settings to give him priority speed when he is gaming. Although he complains about his speeds and connectivity. In our 2nd floor office -- which is one floor and 30 ft through a wall away -- my signal strength varies from 45% to 70%. There are times when neighbor's networks show greater strength than mine does. I live in a house so the physical distance is much greater plus there are two exterior walls, no matter where their router is placed. The adapter in the office computer is a D-Link DWA-556.

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.

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?

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.

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.

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.

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?
