Dell :: XPS-17 - Wireless Network Giving Fluctuating Speed
Jun 17, 2012
Purchased my dell XPS-17 laptop five days ago. When i connect to Wire less and test my download speed it keeps varying ranging from 1Mbps to 40 Mbps. Where the Wire connecting gives a constant speed of 58-62 Mbps. Checked with my Internet service provider. The analysed the issue, logged into my computer in safe mode and the wireless was giving a speed around 55-60 Mbps consistently. They say some application is causing the speed fluctuation. Can you suggest if any of the Dell Pre installed apps can cause this. I have just installed gtalk/yahoo messenger and Winamp from my side , and they are not in the startup menu and not even launched when i test the speed.

I have a question about my Desktop and the Belkin Wireless adapter that I am using for it. There seems to be a problem with my internet connection and I can't figure it out! I'm suppose to have speeds up to 18mbps and I'm only getting up to 5mbps on my Desktop. Now, here's the weird part...when I connect to my wifi on my laptop and cell phone it gets 16mbps. Why this is only happening to my Desktop??? I have the latest wireless adapter driver installed and everything. Is it the adapter or my system??
Wireless Adapter: Belkin F5D8053 N

I just brought this belkin wireless usb adapter N150 and it is giving me slow download speed. I checked on Speedtest.net - The Global Broadband Speed Test and it gives me 0.20 mbps it is not going to the max my max is 3.00 mbps it is not the wireless usb adapter because i checked on another computer and it went to the max 3.00 mbps and i putted it in the same location as my computer so than i realised that it was my computer that is giving slow download speed and it can't find much connections.

Both of these model units apear to have a max Internet downlink speed of about 26 or 27Mbs. I have tested this with 10 different units at 3 different sites where the provided broadband downlink speed is a full 50Mbs, including in my own office. My normal router is a Cisco ASA5505 and I have also connected a Cisco 1840 router and even an old Linksys router and all achieve the full 50MBs speed using a variety of speed test sites. The cable modem at my office and at the other sites have a gigabit LAN connection and the RVS4000/WRVS4400N units certainly should be able to achieve the 50Mbs speed. If this issue can not be resolved, my clients will no doubt want me to install a different manufacturer's unit, which I will do.

We have approximately 150 1142 LWAPP's deployed in our facility. Recently we started getting complaints about speed issues (90% are using G 10% N). Upon investigating we found that the speeds are fluctuating rapidly. Everything from 54Mbps down to 1Mbps and back up again. I've confirmed that this will happen while standing next to an AP (and confirming connectivity to it), however I cannot find anything wrong or anything that has changed with our configuration. We are a large facility and it is happening all over the campus, so I'm fairly certain it isn't any type of 'normal' interference.

My new e3200 setup just fine with Cisco Connect. I have consistently good speeds with a direct ethernet connection, but the wireless speeds fluctuate widely. When I power cycle the router, I'll have perfect speeds for a few minutes and then it'll slow to a crawl (approx 0.5Mbps). Then for no apparent reason, it will speed back up to normal, and then back down to a crawl. I'm using the latest firmware and have allowed Cisco Connect to manage the router so far.This is actually my 2nd router, as Tech Support told me when I experienced this with the first router that it was defective, but I'm seeing the same problem with the 2nd router, so I know something isn't quite right.

I have recently bought a new XPS 15Z Currently when I surf the internet I am unable to use the browsers ( IE9 or firefox ). I am able to use non-broswer related internet applications like STEAM, MSN or QQ with no issues in terms of speed or stability. But when I use my browsers to surf, I can have periodic moments when I cannot surf the internet, such as IE9 which says that I cannot connect to the internet due to some unknown error. But when I run diagnostics, it says that I do not have any errors. My adapter for my wired is the Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20). I have already contacted my ISP provider who have worked for with all the troubleshooting methods they can over the phone, and I trust that they are doing their best. But now it seems to me that the problem lies in my computer hardware or software and not in my router.

My dad recently purchased a wireless LAN card to connect to our router for ADSL internet. The card is labelled on the box as a Mecer WF-2113M 300Mbps Wireless-N PCI-E Adapter. Link: WF-2113 Mecer 802.11b/g/n Internal Wireless PCI-e Card - Mecer
First off I could not get the card to work with the original drivers that came with the card so I updated the drivers. (The card's chipset is a Realtek RTL8192CE). After the driver update the card worked perfected until the BSOD's started completely at random. see attached image with description of BSOD.
PC's Specs:
Asus P8H61M LX Motherboard
Intel Core I3-2100 CPU @ 3,10ghz
2x2gb DDR3-1333 Ram
Gigabyte ODIN 460w PSU
Nvidia Geforce 9500Gt GPU
Windows 7 Ultimate x64
The PC was running perfectly before we installed the card. Is there anything that I can do to solve the issue? Unfortunately I cannot test the card in my PC or my brother's as we both don't have PCI-E x1 slots. Also not sure the PC shop will take the card back.

I have been experiencing fluctuating IP address problems with my pc having windows 7. I've even switched off bonjour and firewalls.In some case it connects to the net but if I disconnect the LAN wire and try to connect to the internet again,I find no connection.
What can be the problem with windows 7,whereas it is fine with my other pc with windows xp in it,thereby indicating that my modem is working fine. MY drivers are also working fine.

I have an XFS 8300 desktop having a TP-Link Model No. TL-WDN4800 dual band wireless adapter card. The box of the card states that the fastest wireless speed available is 450 Mbps. I am using Comcast cable as my internet service provider. Is it possible to measure how fast my wireless connection speed when downloading from the internet? If yes, how?

I have the network up and running fine except that the Windows 7 computer cannot open any files on the xp computer. It says that it doesn't have permission and the check with the network administrator. There are no passwords set up on either computer and both run as administrator. The Windows 7 Computer is hard wired to a Linksys router, and the XP uses a wireless N adapter to connect. The windows 7 computer can navigate the xp computer, it just can't open any of the files with any program. From the XP computer I can access and open anything on the Windows 7 computer?

My Inspiron M101z which I bought last year is supposed to have 802.11n wireless support. However, my wireless speed never exceeds 72.0 Mbps no matter what I do. My router is Linksys WRT160N v3. I've tried everything, setting mode to N-Only, setting channel width to 40Mhz. The result is always the same, I'm getting 72 Mbps max. This speed makes difference when transferring files between computers in the network. All my computers are running Windows 7 x64.

Got an XPS 8300 with a 1501 Wireless-N WLAN half-mini card. I'm using a Linksys WRT160n router which can handle up to Draft 802.11n.
When wired directly to router I'm getting ~21-25Mbps. When I go wireless, it's pitiful - down to ~2-4Mbps. We just got a new laptop in the house (a chromebook actually) and the wireless throughput on that is equal to my wired throughput (21-25Mbps).
I'm using WEP security on the router.
What settings to check/modify to get my connection speed up? Everything I checked seems to be OK and the driver version is up-to-date.

Just received the above laptop from Dell Outlet. First of all I have a dead pixel right in the middle of the screen - will be taking this up with Dell as its really off putting especially on brand new laptop.My second issue is with wireless - did have problems initially with wireless disconnects and generally slow speeds. Im not entirely sure but removing Mcafee seemed to work with the disconnects at least - load of rubbish imo. Now my only other major issue is with wireless speeds on the 1703 card. I seem to max out at about 45mb on all broadband speed tests - while on another laptop I get the full speeds of 80mb on the same server at the same location.
Im only getting a link speed of 72Mbps in the networking tab of Task Manager and this does seem rather slow - the other laptop gets 450Mbps (better wireless card - to go with my Asus N66U Router)Anyway my thought process is that the 1703 wireless card is not up to much in the inspiron 14z- I understand that the 1703 card is wireless and bluetooth - with I think 1 antenna for bluetooth and one for wireless connected to the wireless card. Now I don't use bluetooth much if at all - so does it make sense to buy just a wireless card and connect the two antennas to the card and therefore losing bluetooth connectivity but gaining better wireless connection??? any wireless card recommendations??I think I have an Intel Centrino WiFi Ultimate N 6300 in the other laptop by the way.

Bought a brand new Dell Inspiron 15r N5110 a week ago. I've looked through all the posts. I tried 3 different browsers, I updated drivers, firmware, BIOS, re-seated the wireless antennas under the memory module, even got a new router and modem changed settings on the router, yet still! Every solution I could find, I've executed but still have a wireless speed test yielding less than 1.0 mbps. My 4 year old laptop runs smooth, my iPad runs smooth, all other devices run smooth.

Computer: Laptop Dell Studio 1555 Dual Core: W 7 64 bit, router Sitecom WL-351. Max. connection 120 Mbit. Speed normally approx 100 Mbiton the Dell desktops. Connection speed on the Laptop Studio used to be 60 Mbit wireless . Haven’t checked speed for many week but yesterday foundout that the speed dropped to 12 MB. Wired the laptop to the router, connection wend up to 98 Mbit.
Wireless again the speed dropped to 12 MBit. Checked the wireless connection with another laptop and it went up again to 70 Mbit. What could be wrong on the Studio 1555?
Cleaned the computer, no malware, Mode AP, Channel 11, WPA2
The card Broadcom driver 10-01-2008, version 5.30.21.0
The card works but the 12 Mbit should be at least 60 Mbit.

I am having issues with the connection speed between my computer and my router.We have an airport (time capsule) router and I have a realtek rtl8192ce wireless N card, running a fresh install of windows 7, all updates up to date. The problem I'm having is that I am only connecting to the network at either 1 or 7mbps. It (very) occasionally connects at 29mbps but this is only for a split second and still nowhere near the 300mbs rated speed. I don't expect it to be at 300, however nice it would be to have that,but I would just like a decent rate as my download speed is maxing out at around 2mbs and my upload speed is twice as fast. Another desktop in the same room, next to my current on which is also connecting wirelessly is downloading around 15mb. That connection is either at 29mbps or 56mbps.It is currently connected on channel 7, there is only one other network on that channel in range. Earlier it was connected on channel 10 and there were no other networks on that channel and the connection speed is no different.

My laptop will not connect at full speed whilst on a wired connection. All my other laptops connect at full gigabit speed OK using the same cable. My XPS will only connect at 100Mbps.I have the Realtek PCIe GBE Family Controller.
I am using Win 7 64Bit but I have also tried Ubuntu 12 with the same result. Is this a known problem ?I think this may have been like this since new, My most expensive laptop is the slowest on my network.

My connection is good directly to the modem. But the wireless router is giving off very slow speeds. For instance the modem is 10Mbps but I'm only getting 1.5 - 2Mbps through wireless.

My Home/Small Business network now utilizes several D-Link products. It is comprised of a DLink 205 cable modem (old but reliable and perfectly adequate for the speed I get from my ISP); 2 - DIR-825 Dual Band WiFi Routers (Primary - Rev B1; Secondary - Rev A1); a DLink 5-port Unmanaged Smart Switch (GO series); an HP Proliant N54L Microserver with 6 internal and 2 external HDD's (total of 19TB); 4-5 workstations (HP Laptops); 2 - Brother Laser Printers/Scanner/Copiers; a Toshiba Thrive Android Tablet; an iPad Tablet; Android Smartphones; iPhones; and a large screen HDTV. The Modem, WiFi Routers, Switch, and Server are connected together with CAT6E ethernet cable. The printers are USB 2.0 to the server. The external HDD's are USB 3.0 to the Server.
When I measure transfer speeds of Large files (single 30GB iso movie files) between HDD's internal to the Server and USB 3.0 external <=> internal, I can achieve transfer rates of 140MB/sec - 150MB/sec. This is the limitation of 7200rpm HDD's. When I measure the transfer rate from the Server to a Work Station by CAT6E ethernet cable (25ft length) connected to the DLink 5-port gigabit switch, I measure transfer speeds of around 65MB/sec - 70MB/sec with a peak transfer rate of around 95MB/sec. This is ok but not as fast as other people seem to get. I would be hope to see rates in excess of 100MB/sec. Theoretical maximum for 1GB being 125MB/sec but the specs on the ports say they should operate up to 2GB (250MB/sec).
Wireless transfer rates are where I really am having trouble. Transferring the same 30GB iso movie file over wireless between two Work Stations or between a Work Station and the Server gives a maximum transfer speed of 7.2MB/sec and an average transfer speed of around 4.5MB/sec. If I am streaming multiple streams and trying to transfer a iso file, the transfer speed drops down to as low as 350KB/sec. This is too slow.
My network is setup to do Bare Metal Backups of the Work Stations. This can entail transferring up to 100GB of mixed files to the back-up drives on the Server for each Work Station. At 4.5MB/sec it takes just under 7 hours to back up the Work Station. If multiple Work Stations are backed up, it takes longer. Too Long to be realistic.
How to increase the transfer speeds on the wireless network? I have seen other people post wireless transfer speeds for their networks in excess of 13MB/sec. If I could get 7MB/sec or above when backing up all the Work Stations simultaneously. That would be doable.

I have a 16mbps (megabits) cable modem that is connected to WRT54GL. Desktop is located next to router and is connected with a cable, Laptop is connected on Wi-Fi. Both PCs achieve maximum speed when downloading from the internet but when I try to copy something from one PC to another over the local network I get stuck on max 2.5-3MBps (megabytes).

I have Dell Studio XPS i5 laptop (64 bit) with DELL Wireless 1397 WLAN Mini Card (version 5.30.21.0 from 1.10. 2008). I recently subscribed for an internet connection that requires 802.11n speed. As my wireless card does not support it what are my options here. Is there a magical link to update my card and start gaining from the maximum speed (30 Mbps or higher if I want) or I have to change the card by buying/installing a new one.

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).

I am trying to get my mom's n7110 working correctly in a hurry. The WiFi is painfully slow. It is not the router because I am getting great speed on every other computer. The speed on the n7110 is very unreliable. One second it will be 3mbps or lower, then it will jump to 14mbps.....compared to my inspiron 1545 that gets close to 20mbps according to [URL].
I've tried updating some drivers yesterday, and that worked a little bit because it was WAY worse before that...it would take about a minute to load a picture.any tricks or updates i should look for now?
