Speed max r7000 (300mbps?) problems

• Download speeds slow r7000

  only achieved after 8 months that my router R7000 has always close 3-5 mbps download speed when my ISP gave me 75mbps download.

  I got the scoop from farm last updated and the customer service suggested me to use the channel '11' to 'Auto '. Tried, but for the first few minutes is good, but in no time it sinks again 3-5 Mbps download speed, I noticed that my upload speed is relatively higher.

  One had the same problem?

  Noticed a forum about this problem but no solution in my opinion.

  If you haven't already, I would reset the router to the default values and without making all the other configurations to connect to the Internet without wifi, etc.. Now, let's see how fast you have with a computer connected to the Ethernet port. If it's good, then add your configuration in one thing at a time and test again. This should help you that the configuration option that causes the slowdown.

• Download speed slow r7000 (wired and wireless)

  I have the R7000 for about a year now and originally, I had the good download and upload speeds that corresponds with my ISP rates.

  Right now my ISP (cable) delivers 120 Mbps down and 12 Mbps to the top.

  However, I read an article on a website it my ISP would start by increasing the speed down to 150 Mbps and that in some areas what was already available.

  That of why I unplugged my modem and plugged again after a 2 minute order to restart/reset and hoped for greater speed.

  When I used several speedtesters (speedtest.net, my ISP speedtester, speedtest.nl, etc.), all came to the same result, approximately 90 Mbps down and 12 Mbps to the top.

  Yesterday, I did the test on 2 separate wired computer (HTPC and desktop).

  After connecting my HTPC directly to the modem and the test I got good publicity (120 Mbps down) and 12 Mbps speeds upward.

  Therefore, it is certainly connected to the router.

  Today, I also tried by Ookla's speedtest.net on my S5 Galaxy with 5G wireless and got the same bad results as with the wired connection (90 Mbps down) and 12 Mbps up.

  I am also on a channel that is not occupied by another user.

  I also noticed that the firmware version higher on the R7000 support site is 1.0.4.30, but when I look in the upper right of the router web INTERFACE it shows the version of the firmware V1.0.5.48_1.1.79.

  How is that possible?

  In addition next to the Advanced Settings tab, there is a message that a new firmware is available.

  When I click on this message the router tries to connect to the server to download the Netgear firmware, but after a few seconds it told me that there is no new firmware available.

  I read here on the forum of others with similar problems and tried to revert to a lower firmware version.

  But I could not find an answer to this version referred to a firmware that works best.

  My questions:

  (1) what would be the first thing to try?

  (2) when to return to a previous firmware, what is the best firmware choose?

  (3) what is the correct procedure for the recovery of firmware?

  P.S. for your upload and download QoS information is always off.

  Indeed, the RAM has solved the problem.

  P.S. I accidentally marked the answer of Tarund as the answer to my question.

  Can you please remove that?

• P50D-C-105 satellite speed max RAM taken in charge?

  Hello!

  Just ordered me one of them and I was wondering if anyone know the max speed RAM that
  is supported by the motherboard/bios card? I know that the APU relies 2133 RAM, but will be
  the rest he supported?

  He is coming with just a stick of 8 GB of DDR3L 1600, then fall into another stick to allow two channels
  will be a no-brainer, but I got such a good deal, just thought I'd might as well go for 2 sticks of
  1866 or 2133 so that is supported. Should leave the integrated graphic card stretcht it's legs and then some.

  BR

  AMD Carrizo Quad - Core Mobile Processor A10 - 8700P that is built into the laptop is the memory controller supported DDR3-2133 (35 Watt cTDP).
  So I guess 2133 Mhz could be taken in charge...

  But Toshiba recommends this module:
  8GB DDR3L - 1600 PA5104U-1M8G
  It is of a SODIMM DDR3 PC3-12800 (voltage of 1.35v) supporting 1600 Mhz memory speed...

• Satellite Pro P300-1ES (PSPCDE) - speed with W - LAN problem

  Hello

  just got my new laptop Toshiba (see subject). Unfortunately, I had a big problem with the W - Lan laptop speed.

  Compared to my old laptop (satellite Pro A120, with a chip of WLAN Intel 3945) the new laptop (with a chip Atheros AR9281) scores only about 10% of the possible Internetspeed (approximately 1.5mbit compared to 0.1mbit!).

  I am running Windows XP Service Pack 3 and tried to install the latest drivers for the card Atheros (7.6.0.200), newest Bios Version (version 2.50) and tried a few things on the forum (like disabling the option 'save energy' in the advanced driver options.) But speed has not improved at all and now I'm all ideas.

  I'd appreciate it if someone could help me with my problem. Many thanks in advance,

  Hello

  As far as I know the standard WLan card Atheros AR5BXB91 supports the 802.11bgn WLan.

  Check what WLan standard A, B, G or N to have been chosen in the

• Speed for Wndr4500v2 wifi problem

  Bye to all

  I'm new and I hope you can help me.
  I have a connection fttc 100/10.
  So far, I couldn't test the speed of wifi, cause peripheral material limits.
  I bought a Samsung s7 and I did test speed.
  All my devices supports the 802.11n at 2.4 ghz and 5 ghz both.

  My smartphone can achieve wire speed. I tried with other s7 and the problem is the same.
  I use an Extender (willy 0.2) used by pc reaches the wire speed.
  The Extender even with the Xbox 360 reached 1/3 connection broadband.

  The ports on the router are properly open to the console.
  Finally with wifi network Analyzer app I've found 54 Mbps connection speed, so my router limit the speed in 802. 11A.

  I value 2.4 ghz and 5 GHz networks 450 mbit, removed the consistency of 20 / 40 mhz, but it is always limited.
  I tested with only smartphone connected by wifi, but not luck.

  Can I force use using a router 802.11n at 2.4 ghz and 5 ghz, or I do something wrong?

  Sorry for my English.
  Thanks in advance for any help.

• R7000 + weird problem

  I just took a R7000 to replace an old Dlink DIR-655 for our company to internet hosts. It is run out of its own internet connection. Completely separate from our internet ISP LAN

  This is some weird stuff. I have internet on the R7000, everything works... almost. If I use a computer on this network of comments and access one of our websites which is hosted internally it does not (any serverice hosted internally won't work, WiFi or ethernet ports). Internet connection just directly to our router LAN - DNAT to the internal server. I can see the traffic on the LAN router, nothing is blocked. If I back the Dlink DIR-655, it works again. If I take the R7000 out of the loop and plug the separate ISP modem to direfctly, it works again. Specific to the R7000 Somerthing.

  Makes no sense, it is completely separate internet. I might as well access to tips of my internet at home. Everywhere else works, except through the R7000.

  WTF?

• With the NI 9205 module Max sampling rate - problems

  Dear friends,

  I develop a project of lv, which makes and control system of engine dyno. The material is CRio-9022 with other cards and also 9205 for AI. There is an encoder for angle attached to the motor shaft with 3600 chatted by Tower as well as an index to indicate the end of a revolution. the output of the encoder is measured by card 9411. The speed of the motor is 1500 rpm. I measure pressure data and couple when I receive a 'tick' of the wheel. This means my sampling rate for pressure and torque each is 90KO/s.

  but I was not successful to lead it. The program is great and I can show them, but I believe that there is a problem in the choice of material for the task. With the data of pressure and torque of the 9205, I also measure other channels for the controller output mass flow and temperatures. So in all I use 8 channels of the 32 available. But only the pressure and torque are acquired at the wheel-driven sampling rate. the rest are acquired about 5 times per second.

  Since the 9025 is a multiplexing ADC, 250K sampling frequency is divided by the number of channels accessed = 250 K/8 = 31 K samples/channel. With this in mind, I decided to acquire data of pressure and torque with each beat 3rd rotary encoder, essentially on 30K samples/s sampling. However, I see a large amount of noise.

  So I decide to average more than 1 second cycles (so the engine runs at about 25 cycles/sec, I averaged over this issue). The resulting pressure and torque graphics do not match with those measured by an oscilloscope in terms of amplitude but the frequency and shape is correct.

  I noticed an interesting feature in the charts. When I pass interpolation between the points, I see several curves made by points instead of a continuous locus of points. Accordingly, I find that the acquisition is slower than necessary, and so there are less number of points sampled as required. These points are not synchronized 25 cycles I have on average and therefore the separate "curves". It is because of the possibility that some points receive a higher number of 'contributions' several times (when you add), the neighbouring points.

  so I conculde that the 9205 is not fast enough to do the job. also noise, perhaps due to crosstalk or gosting when the mux changes channels. the impdences output pressure and the couple are of the order of 10 K ohms.

  the Labview code outline: well, there is a vi FPGA, which takes the rotary encoder ticks and sends a signal to the case of each 3rd tick. The signal contains a 16-bit integer, indicating the number of ticks. This signal is sent to a 1 element FIFO. This fifo is read in a parallel while loop, where it remains awaiting a new element. The while loop bed fifo, where data are available, takes a measure of pressure channel. A node memory of the method is called to provide data according to contained in the index number equal to the number of ticks to signal fifo. Then he adds the current pressure reading to the reading of the memory and stores the sum in the same memory location.  Thus, an array of elements of 1200 is formed, where each elemnt is a sum of the values taken of more than 25 cycles. This memory is transferd to a dma fifo and reading side host. is done similarly to involved couple. host-side the fifo is read and divided by 25 to get the average. This average is displayed on a waveform graph.

  Please check the attached file to get an idea of the problem. Sorry for the long post.

  Please suggest if you understand the problem and suggesstions or solutions.

  
  

• Max resolution R61i problem

  Hello world.

  I'm having a problem with a R61i 8930-A97: I can't put resolution is bigger that 1280 x 800 resolution GMA965 max is thus higher.

  Any suggestions?
  Thank you.

  Your screen is WXGA so that he can't handle anything larger than 1280 x 800, if you got WXGA + or WSXGA + or WUXGA then your adjustable resolution higher than 1280 x 800.

• ESXi 3.5 U4 - size Max LUN and problems on HP MSA70 SAS storage

  A few questions...

  What size Max LUNS ESX 3.5 U4 can display/use? I ask because a colleague has a 3 TB LUN and for some reason he does not see ESX.

  Anyone who has used a MSA70 with 25 discs SAS 147 GB on ESXi U4 as shown above? We have problems with it see the big LUN. We created the LUN via HP 'Array Configuration Utility' start to the top of the smart start CD, it went well. Downtown's watch that the controller sees the managed disk 1 lun. But when it comes to installed ESXi he did not see the big LUN. Is there a limit max?

  Thank you

• Windows will not install the USB2 drivers. New Bios, Hi speed ticked. Driver problem! SP2 problem?

  Been trying for weeks to fix this! With a Board of Asus K8vse deluxe. Compatible USB2. But I can't work. System continues to display standard PCi to USB controller. Tried updating driver, but couldn't find an update. But there was an update with SP2 so how to fix it?

  I also tried to install a belkin usb card, but when installing, it installs as standard too. I tried to install software that I downloaded from Belkin. Installed it ok and installs the USB2 drivers but when I plug a USB device in I get the blue screen of death! View of the problem of driver USB2 as guilty.
  Any ideas?
  Been said to uninstall the USB drivers but when I search USB, do not know which. But can't see how it would help if she finds no USB2 driver!
  Help! I HAVE NO HAIR LEFT!

  First thing to do would be to upgrade to SP3 from this link and then get the rest updates and then try it. If I remember correctly the SP3 is much better with USB devices.

  I hope this helps.

• Speed max and the capacity of RAM of Pavilion dv6

  Hi guys,.

  I don't know, you have been asked before, but each post I find little answers my question, but not exclusively:

  What is the maximum speed and the RAM capacity can put in my Pavilion dv6 (Beats edition)? Completely factory standard

  I want the fastest and most large amount of RAM I can get (I'll make heavy photo editing) and then I put a SSD in as well?

  HP Pavilion dv6 Notebook PC

  Windows 7 Home Premium 64-bit Service Pack 1

  Intel Core i3 - 2330 M CPU @ 2.20 GHz

  RAM:

  Slot 1: 2 GB SODIMM Hynix 1333 MHz

  Slolt 2: 4 GB SODIMM Samsung 1333 MHz

  Radeon (TM) HD 6490 M

  Motherboard: 17F9 10.5 A

  BIOS: F.1B

  Sincere greetings

  Justin

  You are the very welcome, Justin.

  Yes, that's correct. 2 x 8 GB PC3-10600 memory.

  Memory will not run any more quickly than the FSB of the processor. Your CPU FSB is 1333 MHz.

  For example: If you have installed 2 x 8 GB PC3-12600 (1666 MHz) memory, he would go only to 1333 MHz.

  I don't think that there is no outside but except DDR5 memory in video cards.

  But you can not mix DDR memory types, because they work with different voltages and the notches are cut at different places on DDR, DDR2, and DDR3 memory modules to prevent someone to install the bad memory in the PC and damage memory, motherboard or both because of the different voltages they run on.

  Best regards

• Problems initializing digitizer card high speed

  I recently built a new computer for data acquisition.  I had all the questions according to a program for the acquisition of data for a digitizer high speed written in LabWindows 8.5 and it works successfully with LabWindows 9.0 on the new machine.  The only problem I encountered was name the digitizer card high speed max the appropriate name of the resource planned by the data acquisition program.  Everything went very well for 4 days.  Today, I try to run the same program and cannot enforce.  Debug code indicates that the device fails to initialize when niScope_init() is called.

  In MAX passes card scanner that can call a test and I have test panels and see an input signal.  I checked the name of the device to ensure that it matches the named resource that provides the program.  I also reset the device to the MAX and then tried to run the program.  None of these attempts succeeded.

  I can't really find anything that changed between the last time I ran the program and today.  Everybody to face this problem in the past, and is at - it solution or a proposed additional troubleshooting?

  This problem has been resolved by reinstalling the drivers for our digitizer high speed.  I have still no idea why after four days, something happened to the original driver installation.
