Dell Inspiron 15 :: Wireless Speed Limited To 72Mbps By Design
Feb 4, 2013
Just purchased new Dell Inspiron 15 (3521). Wireless will only connect at 72Mbps. After some googling found this is by design. The adapter is the Dell Wireless 1703 Adapter. Can Dell pls confirm this is the case and that there is no way to achieve TRUE wireless N speeds ? The fact that this limitation is not advertised on any product material/brochure/sales rep is a concern. Would Dell replace the adapter with one capable of proper wireless N speeds free of charge ?
I just ordered a Dell Studio 14 today, and it comes with 4GB of DDR3 1333MHz ram but in the Order Status page is says that it runs at 1066MHz. I was wondering why it is underclocked. Is it limited by the bus speed? Also, if it is limited to that speed, why would they sell 1333MHz ram if the max speed is 1066MHz?
I'm interested in thickness of HDD in E130. I read that in E125 was 7 mm HDD and there is troubles with 9 mm. So, is E130 similar to E125(E130 is next-gen of this type netbooks, but there is huge posibility that Lenovo Engineers decided not to change HDD type)? Or 9 mm hard drive will work?
Installing msata breaks warranty agreement, doesn't it? amout msata SSD(i've read about installing SSD in other Thinkpad notebooks), but I need some proves for Edge E130:
1)Speed is limited by SATAII interface? 2)mSata drive as bootable device will work? Last questions are not such important, but i'll happy, if Edge E130/E135 users will share their experience
Last month I got a Inspiron 3520 for my daughter and have had nothing but trouble with it. When I plug it in to the router I get download speeds of 35-45 mbps, when I check speed using the wireless connection they range from 11 mbps down to less than 1! It is not the drivers, the power settings, the router as I have followed all of the "fixes" suggested in other threads and run through a 2 hour session with the Dell online chat rep which ended when he had to reboot the machine and the link to return to the chat that he left on my desktop was invalid.
If I move our other HP laptop to the same location (less than 5 feet from the wireless router) that gets download speeds of 25-30 so I am sure it is not the wireless signal. Also we have iPads and smartphones that all work just fine from anywhere in the house. I have tested the Dell speed when there is no one else home and all other devices are turned off and it is terrible. I know this is not a top of the line laptop but I expect it to work at least well enough to be functional. Based on my reading of this and other sites, I am making a guess that the wireless card is faulty.
First of all I have a dead pixel right in the middle of the screen - will be taking this up with Dell tommorrow as its really off putting especially on brand new laptop.
My second issue is with wireless - did have problems initially with wireless disconnects and genrally 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 - 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 dont 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
I think I have an Intel Centrino WiFi Ultimate N 6300 in the other laptop
I have a Dell Inspirion 5520 that has Intel(R) Centrino(R) Wireless-N 2230 built in.Also I have a TP link TL-WR740N wireless router.I have an 80Mbps/25MBps internet connection.My Speedtest result with no router:When I connect all these via an Ethernet cable, I get the maximum even through the router:But when I try to do the same with WiFi I get 30/20 Maximum speed, and I'm sitting next to router!I have this configuration:*router:* -
Channel: auto - Mode: 11n only - Channel width: 40Mhz - Max Tx rate: 150Mbps - Enabled Wireless Router Radio - Enabled SSID Broadcast - Security: WPA- AES - Beacon Interval : 100 - RTS Threshold: 2346 - Fragmentation Threshold: 2346 - DTIM Interval: 1 - Enabled WMM - Enabled Short GI *Intel(R) Centrino(R) Wireless-N 2230:* - 802.11n Channel width for band 2.4 : Auto - 802.11n Mode: enabled - Ad Hoc Channel 802.11b/g: 1 - Ad Hoc QoS Mode: WMM enabled - Bluetooth(R) AMP: Enabled - Fat Channel Intolerant: Disabled - Mixed Mode Protection: CTS-to-self Enabled- Roaming Aggressiveness: 3. Medium- Transit power: 5. Highest- Wireless Mode: 802.11b/gI
do get the fact that speed through wireless is slower than with wire, but losing 50Mbps is a bit too much!
We have several Latitude E7240's on our network. They are configured with Windows 7 x64. We have been having trouble with this particular model in regards to wireless connections.
When the laptop is powered on and the user logs in, the laptop connects to the wireless network, however it is not getting an IP address from the router. It sticks at "limited connectivity", and gives itself a "169" IP. It stays that way for about 5 or so minutes then finally connects.
The WLAN drivers are already to the latest version, and to "bandaid" the issue, I have to uninstall the Wireless NIC drivers then reinstall them.
At first I was thinking it may be a router issue (Which is a Sonicwall TZ210W), but it can't be because its wireless devices of differing models have no problem connecting and getting an IP address. Also, it starts working once the drivers are reinstalled (though I'm not confident this is a permanent fix).
All the E7240's have the Dell 1506 Wireless card, and are all and originally were) on driver version 10.0.0.268, A02. Also, I have tried turned off any power management settings of the WNIC prior to the driver reinstall.
I have an HP 10 S Notebook and I will lose wireless internet connectivity after I've been online for a while. It will show as "limited" and when I click to reconnect it shows I have no internet available. I've run the diagnostics when that has happened and it tells me there is an issue with the wireless card. I can shut the computer down and restart then it's working fine. This has been happening about once a day.
I just got a new Lenovo U430 touch. Major problem: I only get limited wireless. I should note that it hasn't connected wirelessly once. It does connect fine via LAN ( I kept the cables!). I tried calling Lenovo but they said it must be my router and I should contact my internet provider (which I don't understand since the internet provider has nothing to do with the router.)
The laptop does connect wireless for about 5 seconds (I once managed to open an email before the connection slipped). Then it shows the yellow exclamation point in front of the wireless icon on the right-bottom screen. If I troubleshoot, it fixes the default gateway. Repeat. Sometimes it says that the "default gateway is not available."
Things I have tried per other similar questions asked online: unistalled McAfee, including with the removal toolpower cylcing my router, laptop, and cable modemuninstalling the wireless driver and restarting the laptop Some notes: the system came with Windows 8.1I have two other devices wirelessly connected to the same router with no problem. I'm sitting about 8 feet from the router.the only programs I've downloaded are Firefox and then finally Kaspersky (since I uninstalled McAfee) I'm pretty good with computers, but this seems beyond me. It's a new laptop and it should work, darn it!
This question pertains to all laptops but since I'm running a m1710, I hope its OK to post it here.
I have 6MB down DSL at my place. I was running it thru a Netgear RangeMax Wireless Router (WPN824). In my laptop, I have a Gigabyte GN-WI01GT (mini) PCI-E WLAN card. When everything was running smoothly, I noticed that my connection "speed" was fluctuating between 54Mbps and 108Mbps. My first question is: how do I maintain the 108Mbps speed?
With my wireless adapter, I had initially let Vista install the drivers. Then I had the bright idea of going to the Gigabyte site and getting their latest drivers. I did this because it seemed like I was always on 54MBps and no longer jumped to 108Mbps. Ever since I updated my drivers, my router hasn't been working and needs to be set up again. I found this to be pretty strange.
Also, my interet isn't as fast as it was on day 1. Is this normal for DSL? Or is there something on my laptop degrading the connection? Is that even possible?
I haven't gotten around to reconfiguring my router but I did uninstall my wireless adapter and let Vista find the drivers. Would you guys recommend this process or using Gigabyte's drivers?
I have an XPS M1710 and it has the 3945ABG wireless card. Just today I upgraded my internet speed to 15Mb down. When I go to www.speedtest.net I get a result of 5Mb down.
I have tried the same test on one other laptop (not a Dell) and another desktop. None of the components involved are capable of 802.11N so I know its not that. The wireless router being used it Linksys WRT54G.
One more note, when I connect the router, or modem up directly to my NIC I will get the fill 15Mb.
I have just received my new Inspiron 15R which I cannot fault, even after the minefield of getting to grips with Windows 8.........However for some reason my wifi connection will be stable for about 10 minutes and then show limited connection with no internet access although the network connection is very good! All other laptops and devices are still connected!
I just found this weird occurence. I often use my Vaio Z with external monitor. So most of the time I have my lid closed. Accidentally I was opening my Network Status and noticed that my wireless speed was only 1Mbps which was pretty aweful for an N speed. I was pulling my hair off, trying to figure out the problem with the setting. By looking at the signal, it was still pretty decent 3 bars.
Finally I found out that, whenever I opened the Sony Z lid , the speed would jumped up to 90Mbps and over maximizing around 150Mbps. Surprisingly the signal quality remained the same around 3 bars.
Did anybody experience this as well? Is it normal? Why did this happen?
I already turned off power management for wireless Intel 5100 AGN as well.
I have got a new Dell Inspiron 3521 i5 with 4GB RAM - 64 bit OS - Windows 7 - Service Pack 1 Laptop, everything works good except, the problem with my Wi-Fi Connectivity.
The issue I'm experiencing is with the Internet connectivity, my Wi-Fi connectivity loses frequently and I get message saying "Limited Access", and gives me an option to reconnect it manually which is a bit disappointing. .
Rest all works pretty fine, I'm satisfied about it. Just this error, disappoints me.
The troubleshooting I have tried so far is -
1) Resetting router for 30 seconds and restarting it - did not fix my problem.
2) Checking firewall settings - did not fix my problem either.
I just upgraded to 4gb RAM on my 1521 from 2gb. After I installed it I checkethe <Properties> on XP to see if all the RAM was showing up, 3.37gb showed up. But I noticed the processor speed was down to only 795mhz, so I checked it with CPU-Z again and that read 795mhz as well.
I went into BIOS and turned off the AMD PowerNow option and it bumped it back to 1.9ghz. I ran CPU-Z again and it was at like 1.895.2ghz, but i noticed the bus speed was down to 199.5 mhz. Shouldn't that be like 333 or something? I've attached some screenshots from CPU-Z after turning off AMD PowerNow, with PowerNow all cpu specs are much lower.
I would like to upgrade but I can't find information about my motherboard ANYWHERE. It's not listed on the dell system specs website, either.
So, my question comes down to which would be better: PC-5300 (667Mhz) ram with 4-4-4-12 timing or PC-6400 ram (800Mhz) with 5-5-5-18 timing?
What is the maximum speed of memory that the e1505 can use? If it's 667 Mhz, I'm of course going to go for the ram with faster timing, but if it's 800 Mhz then I'll go for the speed. I'm using a 2.0 GHz core 2 if it matters, and all I could find it bios is that it's a mm061 "system
I have a 1520, 2Ghz Duo, 2.5 Gb Ram, running XP.....I also have a Line6 Guitarport USB audio interface. When I use this the audio often drops out a lot, especially when acessing the hard drive - what can I do about this? -
it's a 5400RPM drive - will upgrading to a 7200RPM improve things? It seems something is effecting the USB data stream.
The hard drive I have is a WDC WD1200BEVS-75UST 120GB
Also, is the drive running in SATA mode - when using HD tune it says: Standard: ATA/ATAPI-8 - SATA I
I've downgraded my Inspiron 1420 recently to XP SP3 with all the device drivers properly installed. Everything seems works fine except that I found fan1 & fan2 always on at max. high speed (very noisy) and CPU always max. at 1.5GHz (seems lost SpeedStep control, checked enabled in BIOS, with SpeedStep control cpu speed should drop to lower rate while the notebook is idle), the fans and cpu speed status are checked via the utility program I8KFANGUI.
If I enabled automatically temperature control in I8KFANGUI then fan1 can turn off as cpu cool down to below 55c and only turn on at Low speed at 60c (still very quiet, noise no noticeable) but still fan2 is always high at 4XX RPM constant rate, I8KFANGUI in fact reported fan2 is not controllable even for just turn on and off .....
i really want to get rid of this stupid annoying speed-step technology. there is an option in bios that will allow me to turn it off, but it will put the processor at 1.2 Ghz, i want it at its fullest at 2.00 Ghz,
I have two apparently identical Inspiron 8500's. Intel Pentium 4-Mrated @ 2.4 Ghz.
One runs at 2.4 Ghz as shown in system properties, CPU-Z and other utilities.
The other runs at only 1.196 Ghz max, shows 1.196 Ghz in BIOS. Bios version A08 apparently the latest offered.
I've tried swapping batteries, power supplies and cooling fans. The fans and grills are clean, and the BIOS proves this isn't an issue of temperature or something that changes after bootup. I've installed speed switch XP, which also shows 1.196Ghz and nothing can be set in that program that changes it either.
I've downloaded the "Speedstep" software update from Dell ... no solutions there. It doesn't step down or up, just runs at max of 1.196 Ghz, which is of course noticeably slower than its twin.
I recently downloaded A06 version of the Dell Inspiron 15r 5521 bios, and I was wondering if (and how) it is possible to change the fan speeds and temperatures for my system. I can't find any option for this.
