Lumia 820 - Dual Band Wi-Fi

Can anyone confirm whether the Lumia 820 supports dual band Wi-Fi? Can it connect to 5-GHz networks?

I can confirm that the Nokia Lumia 820 does support the 5 Ghz Wi-Fi band under the 802.11n standard. UPnP streaming on the phone to Bluetooth headphones is working well. However, I'm looking forward to the update which allows Wi-Fi while the device is on the lock screen.
Definitely wrong. I can confirm without a shadow of a doubt my Lumia 820 is connected to one of my 5ghz routers on 802.11n as I am typing this. If you are not able to then you have an issue with either phone or router.

  • 4G support for Lumia 820

    After launch of 4G LTE on 1800 MHz band in Pakistan can i expect Microsoft Devices to enable 4G in my Lumia 820 through the upcoming Denim update? Currently although i have a LTE sim, highest connection speed is shown as 3G. I have read on a blog that denim or 4G connectivity may not be offered for 820. I would emphasise that someone from Microsoft Devices may kindly clarify so i may plan to ditch my phone in case this is true!

    Microsoft have inherited Nokias way of doing things, so they work with local operators to have the phones approved to use on the particular network before releasing updates, and before enabling new features. Other vendors may release phones and updates and hope it will work. My friends often complain about dropped calls on expensive, competing phones, something that has never been an issue on my Nokia phones.
    The particular trouble with LTE/4G is that phone calls still need 2G or 3G in most areas. This fallback is not trivial to do, since it is very different technology. Also since there are at least three major network hardware suppliers (Nokia, Ericsson, Huawei) to provide the equipment for the cell towers, this in itself can be challenge. There are official industry standards to ensure compatibility of course, but I prefer something that is tested and approved for my region.
    LTE is still work-in-progress. I keep the money for a new phone in my pocket until my operator enables phone calls on 4G (VoLTE) which completes a phone call in less than a second, instead of an up to 10 second wait. the long-range 700Mhz frequencies for rural areas will be nice too, and then there is carrier aggregation for even higher data speed. It is nerdy stuff, but that is how I am.
    It is very unlikely that you will get an official response from Microsoft, so I hope this helps.

  • Vertical streaks on Lumia 820 display

    I see very distinguishable vertical banding and streaks on my Lumia 820. I first noticed them on dark grey backgrounds but now also on e.g. Nokia TV menus. Is this normal?

    no this is not normal at all. have you tried performing a soft reset (pressing the volume down and power buttons together until the phone vibrates)? Failing that, it sounds more like a case of hardware failure so you will need to take your phone back to your point of purchase...if they are being less than helpful, then you will need to take your phone to your local Nokia Care for inspection: http://nokia.com/support

  • Nokia Lumia 630 - Dual SIM / One SIM network diffe...

    I was just about to buy a Nokia Lumia 630 Dual SIM here in Thailand , my mobile SIM card only works of the 3G band - 850Hhz , I was told by the sales person that the Nokia Lumia 630 Dual SIM only has the 3g frequencys of 
     HSDPA 900 / 2100 
    but the One SIM version has the 3g frequencys  of   WCDMA/HSDPA Quad Band  850/900/1900/2100 MHz 
     I know that mobile phones can be different 3 g frequencies in different countries , but I wondered what you guys thought .

  • Lumia 820 and LTE enabled firmware. Czech Rep.

    I have Czech distribution of Lumia 820 with LTE disabled. Now all mobile operators in Czech Rep. are starting to build LTE networks - like Vodafone i my area (http://www.vodafone.cz/o-vodafonu/o-spolecnosti/pro-media/tiskove-zpravy/detail/vodafone-spousti-tes...)
    When will be new firmware distributed in Czech Rep. for Lumia 820 with LTE bands enabled? Thanks.

  • Time Capsule disk access SLOW!   2TB - Dual band

    I have a Time Capsule (2TB, Dual Band, Firmare at 7.4.2)
    Its been working like a dream, backing up 3 Macs for the last 8 months.
    I also use it for connecting two or three other disks via USB and then making those accessible over the LAN, and there is also about 100GB of data on the Time capsule disk itself that i use as a dump for files so i can get to them from anywhere on my LAN.
    Lately I started to notice EXTREMELY slow disk access, even when i am connected via ethernet (1000 base) - and equally when I am connected via wifi (n)
    for example, copying over a 2Mb photo can take minutes when it should take seconds.
    i've been trying to figure out whats going on here for a while and so i checked out the sizes of the backup files.. the sparseimages that time machine creates.
    one of them was nearly 1TB, while another was around 500GB and the other was around 120GB
    that plus my data meant there was only about 300GB free on the 2TB disk.
    I have a feeling the slowness could be down to extreme fragmentation of the drive... ??
    so i decided to dump the backup files and copy off my other data and do a erase of the disk and start again.. but get this.. i can't even delete the 1TB file ! I have been trying for about 3 days now and it just will not delete.. i get the Deleting msg box and it just sits there, literally ALL night...
    i know it isn't just hanging on the Mac (10.6.4) because deleting the other two images also took a long time (but not this long!)
    i can't just wipe the disk now because i can't get my other data off either.. I have tried copying it over the network and onto a USB disk connected directly to the Time Capsule, but 3 days later and i'm still copying files..
    to put some context into this, I copied over 1.8Gb today and it took about 4 hours...
    has anyone had this problem before?? what on earth is going on?? is it down to fragmentation, or something else?? the TC has been working fine up until a few weeks ago when i started to notice slow speed.
    any ideas ?
    thanks
    Adam

    if anyone ever has this issue ....
    it must have been EXTREME fragmentation. I bought another 2TB external disk, connected it to the TC, did a complete archive, which took around 24 hours... then i wiped the TC and put stuff back... it now works fine again...

  • How do I use the remote app on a dual band network?

    There are 2 routers in my home. One is dual band (SSID: NETGEAR49-5G). This one is being used as a 5GHz access point while the other (SSID: NETGEAR49) is being used as a 2.4GHz extender. However I can't use the Remote app to control my iTunes library, regardless of which router I connect to. I can't even use a passcode to add my library because I just keep getting an error saying I entered the wrong code. Strangely everything's fine if I turn off the 2.4GHz router, but I don't want to have to keep doing that. Is there any way I can configure the two routers so I can use the Remote app and other network-based services??

  • Dual-band wireless question

    Hi again: I am new to this dual-band wireless stuff in TC having just replaced my AE with a new TC. I have a few questions regarding wireless setup.
    1. When selecting the "Radio Mode" you are presented with options like "802.11a/n - 802.11b/g". Does this setting mean that the primary wireless will be a/n wile the guest wireless will be restricted to b/g ?
    2. If you Option-click on the Radio-Mode pick list you can select multiple other settings. On of which is 802.11n (5 ghz) - 802.11a/b. Give question 1 does this restrict the main wireless to 5 ghz n only? (I highly doubt this as I can still connect to the "n network" with my iphone which only supports b/g.)
    3. Under "Wireless Options" you can select a "5 ghz" network. Is this different than the option detailed in Question 2?
    4. Finally, where can I find a manual for TC ?
    Thanks for the help, Chris.

    So is my assumption that the hyphen in the selection is the differentiation between the two networks?
    Also, when I activate the "5 ghz" setting under options I actually see three networks, "Network1 (5 Ghz), Network1, and Network2 in my naming system. Does this mean that Network1 (5 Ghz) in the N only while Network1 is a standard N (with backwards compatibility to b/g)? I think this is the case as my iPhone does connect to Network1 while Network1 (5 Ghz) is not detected.
    Thanks for the help, Chris.

  • How can I get Wireless N 5MHZ Capabilities Dual Band up to 300MHZ on my DV7 Laptop?

    How can I get Wireless N 5MHZ Capabilities Dual Band up to 300MHZ on my DV7 Laptop?
    Question for 4/18 experts ...
    Or specifically, how can I replace my wireless card on a DV7-6B32US and upgrade to Intel Centrino 6230?
    I have a relatively new DV7-6B32US puchased on 11/2011.  Still under warranty. purchased 2 of the laptops. (also own 3 hp desktops and 1 HP All in One)
    Existing card is wireless N but does not support 5GHZ or dual band.  It is Broadcom 4313 wifi card and I am just realizing that the Broadcom card does not do the dual band  5GHZ wireless N.   I have Linksys e4200 router which supports 5GHZ and dual band speeds up to 300 Mbps.
    I called tech support and with their help identified Intel Centrino 6230 as the correct upgrade, and with their help ordered 631956-001.  In the Maintenance Manual for DV7 laptop, this part number was listed for Intel Centrino 6230.  Turns out HP sends an Intel Wireless N 1030 card, which is no better than my existing card.   I called HP and they acknowledged that some manuals use part number 631956-001 for Centrino 6230 and some use 631956-001 for INtel 1030.  So HP support said they would give refund but case manager was of no help in solving the upgrade problem.  Said it was unavailable but here is your money back.
    So after more searching, I see others have used part number 636672-001 to order Intel Centrino 6230, specifically for HP ProBook 4530s, 4230s, 4730s.   And if I use part number 636672-001 and go thru parts store at HP, I can purchase it. 
    But will it work??
    First, will the Intel Centrino 6230 with part number 636672-001 from HP parts,  work in my HP DV7-6B32US, even though the part number is NOT listed in the Maintenance and Service Guide for my specific  laptop.  I see postings about whitelists and changing bios, etc, and am hoping someone can provide some guidance.   I have been thru 2 tech support calls and one case manager and have gotten 3 different feedback from HP, from yes it will work and ordering the part, to buy it on amazon, to it will not work and here is your money back.
    Second, I see some postings about Centrino 6230 and multiple antenna's.  When I replaced the Broadcom 4313 with the Intel 1030 card, I simply unattached 2 wires and reattached the wires.  And it worked.   I am wondering if the reason HP doesn't list the 6230 card for DV7 is that DV7 does not have the antennas required to support 6230.   Does the Centrino 6230 require 3 antennas?
    Thanks for any suggestions.  The existing cards do work but I paid extra for the Linksys e4200 Router and just assumed a winter 2011 $700 laptop from HP would use the latest wireless n technology, otherwise I would just keep existing cards. 

    I have went thru the exact same problems trying to upgrade the wireless card in my DV7.  It is very frustrating that the wireless card can't be upgrade to one that supports 5Ghz.  Here is my post from the network forum. http://h30434.www3.hp.com/t5/Wireless-Internet-Home/Unsupported-Wireless-LAN-6230/td-p/1419595 Doesn't sound like it is possible to upgrade to the Centrino 6230 without it being added the the "white list".  Sound like HP doesn't update the list after shipping the notebook. I feel your pain. HP needs to help out the consumer in upgrading the wireless cards.  I see we are not the only ones that have had this problem. 

  • How to set-up a DUAL BAND wireless network.

    Lots of people are reporting problems caused by replacing an existing wireless network with the new Airport Extreme 802.11n base station.
    * Xbox360 compatibility.
    * Airtunes issues
    * 802.11n slowed down by 802.11g devices
    One workaround is to set-up a dual-band network. Your old 802.11g base station looks after the older "g" devices. And the new Airport Extreme looks after the 802.11n devices.
    There are a number of benefits to this solution.
    * Everything that did work, carries on working. No reconfiguring needed.
    * Everything works at its fastest possible speed. You can use the full 270Mb 5Ghz band for n devices.
    * 802.11g traffic does not interfere with 802.11n traffic at all.
    * It's easy to set up.
    The downside is
    * There are two boxes. I want one.
    This is the diagram (again)
    Note that in this configuration, the new Airport Extreme base station is set-up in Bridging Mode.

    I've done some testing and here are my findings:
    - 2 Computers, 1 C2D N enabled and iMac G only in 2 diff rooms
    - 2 AX to stream music
    - Transfer of a 446 Mb avi file from Airdisk to C2D
    - 2 Wifi Networks: 1) G only from a Netopia 2) Depending from settings from AE(n), Both Base Station are placed aside. When G network is available both AX are connected.
    - With or No airtunes means a stream to the 2 AX from iMac while transferring the 446 Mb file to the C2D.
    446 MB / AE(n) 5 Ghz N / No Airtunes / Netopia Off / 2:47
    446 MB / AE(n) 2.4 Ghz N Only / Auto Ch / No Airtunes / Netopia Off / 2:13
    446 MB / AE(n) 5 Ghz N / No Airtunes / Netopia On / 3:14
    446 MB / AE(n) 5 Ghz N / With Airtunes / Netopia On / 3:20
    446 MB / AE(n) 2.4 Ghz N Only / Auto Ch/ No Airtunes / Netopia On / 2:29
    446 MB / AE(n) 2.4 Ghz N Only / Auto Ch / With Airt / Netopia On / Unusable
    446 MB / AE(n) 2.4 Ghz Mixed / Auto Ch / No Airtunes / Netopia Off / 2:17
    446 MB / AE(n) 2.4 Ghz Mixed / Auto Ch / With Airtunes / Netopia Off / 3:03
    Here are the findings:
    - Without any G network (meaning no Airtunes possible) the 2.4 Ghz N Only performs much better than the 5 Ghz N
    - While streaming Music the 2.4 Ghz Mixed performs better then the 5 Ghz N (Dual Band Network)!
    These are my findings with my settings, it could be different, but I'm pretty sure you will find the same behavior on your side. And BTW, the theoretical thru-put means nothing, only real life usage testing is worth something. So on my side I'm going for a single mixed network.
    Hope this sheds light for some of you.

  • I have set up a Netgear dual band modem which works well with the iPhone and an older MacBook, but with this brand new MacBook it asks for a password every time I reopen the computer and open safari. Is it Lion?

    I have set up a Netgear dual band modem which works well with the iPhone and an older MacBook, but with this brand new MacBook it asks for a password every time I reopen the computer and open safari. As you can imagine this is very annoying. It says I am not connected to the internet and offers me a choice of nearby networks including mine and then asks for a password when I select it. Why does it do this with our new MacBooks (also with my son's brand new one) and not with the iPhone, iPad and older MacBook? They happily automatically connect to our network after entering the password just the once.

    Sig, I appreciate you trying to be helpful. I have no idea what issues you were having or what issue exactly pgrounds has been having. Your assumption that everyone's set up is the same as yours is false however. There are many many documented WiFi issues that are a result of Lion installs. Many have been solved by 10.7.1 and 10.7.2. Others have been solved by a large variety of work arounds. Others have not had their issues solved yet.
    I am one of those. I have an IT background, and I spent the better of five hours digging up workarounds and attempting all of them. For the benefit oh anyone who is having similar issues, I have posted links to all of those workarounds here. None of them worked in my case, but hopefully they will help pgrounds or others.
    So, once again, if you have a new idea, I'd love to here it. But if it has already been posted in one of these links, it's not helpful, let it go.

  • My problems with Nokia Lumia 820

    I was a big fan of Nokia until two months back when I purchased Nokia Lumia 820. It's been two months and I'm having tough time with the handset.
    First it was the heat issue. I know smartphones are tend to get heated up due to processors. But my mobile gets heated up in less than 5 minutes when I play games like real football, wordament and even simple games. I thought I got a bad device out of the box. When I say heated up it's not warm, its hot and uncomfortable hotness. I can't hold my device until the heat subsides. I visited the Nokia care for raising the heat issue but they said they can't do much and updated my mobile to the latest firmware (1308) and asked me to check after the update and the heat issue is still the same. Just when I thought things can't get any worse it did. My mobile has visited Nokia repair factory already twice in less than two months of purchase. The first major problem occurred three weeks back when the display would be switching on and off randomly and finally the mobile got bricked. The screen went blank completely and the device was unresponsive. Along with that complaint I've again raised a complaint about the device getting heated up uncomfortably. 14 days after I submitted my device to Nokia care I got my device back only to find that the screen isn't responsive to touch in the middle within a week's time. The upper part and the lower parts are responsive, it's the middle strip that's not responding to touch.
    I've again given my mobile to Nokia care and they have sent it to the repair unit. In two months of my purchase the mobile has spent more than 4 weeks at Nokia repair outlet. It is still undergoing repair in the Nokia repair factory. I had least expected this from Nokia.
    Some of my friends who have windows 8 phones from Nokia haven't experienced any problems so far, not even heating problem. It's safe to say that the problem is only with my device.
    It's two months old and I've got it from the Nokia priority dealer.
    What'd you call a device which spends more than 40% of the time in the repair factory in two months of the purchase. Even the 3 months EMI's haven't been payed fully.
    I've encountered lots of inconvenience after purchasing the device.

  • Dual Band (5ghz and 2.4 ghz) Wireless Network Config and Dropped Connection

    Hi, I have an Airport Extreme (802.11N) and a Motorola WR850G (802.11A/B/G) that I'm trying to connect in a dual band setup - but something in my setup is causing the Airport to drop it's connection (before the connection is dropped - everything works great). After I lose connectivity, both routers show up in my list of wireless networks, the light stays green, but I don't have local or internet access. When I try to reconnect, the log on times out. Also, the Airport isn't displayed in the Airport Utility (light is green on the airport itself though). Unplugging and resetting the Airport Allows all computers on the network to connect locally and to the internet for a few hours until the connection drops again. While it is up and running, I have no problems streaming movies off the connected Airdisk, navigating the internet, and connecting both N and G devices to the network.
    I'd love to hear from you if you've gotten a similar setup to work, and if possible, have you provide the settings you used to make this work. I've looked around quite a bit and haven't seen a detailed description of the process (even from the Apple documentation). Also, advice from anyone would be greatly appreciated since my wireless networking knowledge is pretty basic.
    My configuration:
    Time Warner cable modem connected to the Airport's WAN port. WR850G connected by LAN port to Airport's LAN port. Bridge Mode check box selected on WR850G. Airport setup for 802.11n (5Ghz). Unique SSIDs to determine which network is 'N'. Same password for both networks. My Firmware and utilities are up to date.
    Computers/Devices on Network:
    Two Macs with Airport Extreme N cards. A Vista PC with a D-link N card (only compatible with 2.4 Ghz so it connects to the G network). A Vista PC with a GB ethernet card connected to the Airport Extreme. Various other G devices like iPod touches and an old iBook. Airdisk connected to the Airport Extreme.
    Thanks,

    I removed the second router (Moto wr850g) and everything seems to be working smoothly. It must be some settings on that one that are causing the problem, but I haven't been able to get it configured correctly. I noticed there were some IP conflicts with my wireless wanting to use the old Moto router IP and trying to assign my Mac an IP from that router. Does anyone know specifically what needs to be disabled on a router in bridge mode? Since I have a third party router there aren't any handy wizards that can configure it for me.
    Thanks again

  • How can I tell if I need a Dual-Band Wi-Fi Dongle ...

    Hi
    I've just placed an order for BT Infinity 1 and have been advised I will be receiving the new BT Home Hub 5.
    Can someone explain if it would be advantageous for me to order a Dual-Band Wi-Fi Dongle 600 or not?
    How can I check if my laptops - Dell Studio 1749 and HP ENVY dv6 - can already handle dual band connections, if that is what we are talking about here?
    Any advice / help appreciated.
    Thanks
    Solved!
    Go to Solution.

    To be honest, you are unlikely to see any speed improvement by adding a wifi dongle, also the 5GHz band has very limited range.
    I would wait until everything is working, before ordering any more stuff.
    There are some useful help pages here, for BT Broadband customers only, on my personal website.

  • Best way to add new dual band Extreme to existing b/g network

    I've been using a Snow Extreme and b/g Express, but have recently been having dropped/slow connection issues. I think this may be at least partially caused from the many other networks and other wireless devices in the neighborhood - I can see 30 or more networks at times. I've also gotten a new Mini and MacBook, both with n wireless, so I decided to get a new dual band Extreme.
    The faster connection speed of the new Extreme is very noticeable on my n capable machines. It also looks like the connection issues I was previously having may have been resolved, but its a bit early to tell for sure.
    First problem I've had is with setting up the guest network. If I attempt to set it up wirelessly, I get as far as changing the settings and restarting the Extreme. Once I do, it does restart, but then Airport Utility is not able to find it after restart. I am able to see the main and guest network in my available networks, but I am unable to join either. Once I turn guest off (via ethernet since Utility isn't able to see it wirelessly) I am again able to see it in Utility and connect to the main network. If I try to turn on guest via ethernet, I get an error and it does not restart.
    Originally the Snow Extreme was the main and the Express was used for wireless printing. My plan was to use the new dual-band as the main, move the Snow to the printer, and use the Express for AirTunes. But now I realize that I'm only able to print and use Airtunes on the main and not the guest network. Since the Snow and Express are b/g, are they going to slow down the main network? I am seeing these as clients in Airport Utility, which I didn't expect. If so, is there a better way to set this up than what I am attempting to do?
    I've got the radio mode set to 802.11n only (5GHz) - 802.11b/g/n. Am I able to set it up so that the n capable clients use the 5GHz band and the b/g clients use the 2.4GHz band so that they don't slow down the n connection, or would I even want to do this?
    Thanks!!!

    The jre is 14,872 KB (j2re-1_4_2_03-windows-i586-p.exe).
    If you silently install the JRE then then licensing doesn't appear to be an issue (no dialogs appear). See http://java.sun.com/j2se/1.4.2/docs/guide/plugin/developer_guide/silent.html. Silent installation is perfect for us since our customers are very nontechnical and would be very confused about the JRE installation dialogs.
    My main question remains: what is the best way to incorporate the installation of the JRE into an existing product. I solved the above-mentioned error 1500 problem by asynchronously starting the silent JRE installation after my product is installed, i.e., after the InstallFinalize step. This results in a bad human interface: the user is prompted with the final dialog with a "finish" button. However the mouse cursor is showing an hourglass intermittenly (kind of like when you logon to Windows after a reboot), for 25-40 seconds after this dialog first appears, until the JRE is installed. I have got to figure out a way to synchronously install the JRE while the user waits.
    I chose to do a private install (search for "private" in http://java.sun.com/j2se/1.4/pdf/plugin-dev-guide-1.4.2.pdf), which works, but I haven't yet figured out the best way to uninstall this JRE -- it appears that simply deleting the directory tree might be the correct way to uninstall.
    I have searched a lot of newsgroups for the "generally accepted" method to incorporate some Java programs into a product (i.e., how to install the JRE). I have not found anything. My conclusion is that I must be doing something that isn't done that often, either that or I've taken a wrong turn.
