WRT54G v4 unusable web interface after firmware update

I tried to upgrade (actually downgrade) my WRT54G v4 firmware 4.30.11 to 4.21.1. When the progress bar reaches the mark to halfway, I got the message saying that the upgrade was successful. However, now the web interface is so messed up that it is unusable. It's a sign that something went wrong.

Power, WLAN, Ethernet 1, and Internet lights are all green solid, which should be a good sign. After the upgrade, the web interface says "WRT54G 4.21.1', which is the firmware messed up I am downloading. Browsers, then restart my computer, I have confirmed that it is a router problem, not a problem of the browser cache. I also tried to do a hard reset by pressing the reset for 30 seconds button, unplug the router while holding down the button of reset for 30 seconds and then plug the router while holding down the button of reset for another 30 seconds. This has not fixed anything.

I encountered a similar problem after an update of the firmware several years ago and the fix to upgrade the firmware using TFTP. This time, however, the TFTP utility could not download the firmware. Using a hack that I found on the internet, I have re - download the 4.21.1 firmware, but the web interface was always messed up. I then downloaded the 4.30.13 firmware. The web interface is still messed up, but then he said "WRT54GL 4.30.13. I then went to the firmware I wanted, WRT54G 4.21.1. The web interface is still screwed up, but said «WRT54G 4.21.1»

Anyone know how to solve the problem? Yet once, it took place immediately after a firmware update, the web interface is unusable, is not a problem of the browser cache and tried a hard reset.

Thanks in advance if anyone can help.

My router model is WRT54G v4. The v4 WRT54G and the WRT54GL are generally considered to be the same device with different model numbers. According to the article of Wikipedia WRT54G, "the WRT54GL is technically a reissue of the version 4 WRT54G."

I used the firmware 4.30.X for years without problems. However, I decided to switch to the 'right' firmware for my router and something went wrong during the upgrade.

I solved the problem. I basically just dropped the Linksys firmware and uploaded the DD open source-WRT firmware mini instead. Now everything works fine.

  • WRT160NL cannot connect to the web interface after firmware update

    I've updated the firmware to unofficial http://mirwifi.org/download/fw/WRT160NL/wrt160nl-0.1.3-pre5.bin and since then I can not connect to the router through the web interface. What can I do? Is it possible to update the firmware to the official without web interface? Thanks in advance for any help.

    The router's default IP address is 192.168.1.1. Try to ping the IP address of the router and check if you get answers from the router.

    Open the Internet browser and in the address bar type http://192.168.1.1. See if you can open the router configuration page.

    If this does not work then you can try to update the official firmware on the router using the TFTP.exe file.

    Disable the firewall on your computer. Connect the computer to the router with the Ethernet cable.

    (1) download the official firmware file from the site Web of Linksys router. Save it to your computer.

    (2) download the tftp site Web of Linksys. Follow this link to search for the file tftp. You'll find downloads for router BEFW11S4. Select the version 3.2 hardware and download the installation wizard. Save it to your computer.

    (3) run the installation wizard. In the server box, type the IP address of your router. In the password box, type the password of the router. Default password for the router is admin. Find the file of the official firmware you have already downloaded and click on upgrade.

    See if it works.

    After upgrading the Firmware on the router, it is recommended that you must reset the router and reconfigure.

    Press and hold the reset button on the router for 30 seconds. Release the reset button and wait 10 seconds. Power cycle the router and reconfigure.

  • jumble of text in the web interface after Web Services update / firmware

    I received a message on the screen of my Officejet 6700:

    Update recommended

    An update is available for Web Services (ePrint and Apps).

    Do you want?

    I chose to update now and it installed fine, or so I thought.

    I checked the web interface of the printer, and there is a bunch of text confused, as the code is messed up for the web server.

    I had just finished to check the status of your ink cartridges (and subsequently replaced a), so I have the fully functional Web page fortunately still open on another machine, so I can tell exactly what is forward - after on this page.

    On the tools > gauge of ink page, on the right page (old) the said table (title, first line, first column):

    Cartridges installed

    Color | Magenta | Cyan | Yellow | Black

    Part number

    Type

    End of warranty date (A-M-J)

    First Installation Date (A-M-J)

    Area of ink

    USE

    HP

    But after the software update, it says this:

    Print the self-test Page

    L@S#0456 | Number of recorded events. L@S#0462 | L@S#0552 | L@S#0450

    Use of the accumulated media

    Date

    L@S#0477

    L@S#0561

    L@S#3345

    In addition, the order "supplies" link, with a contextual text of "print order supply."

    now, says "Cartridge", with a contextual text ' block unwanted faxes '

    And "Print Printer Status Report" now says "L@S#2567".

    I went to the support section and found an update firmware, but during download and execution, after you find the printer, he says that he is already up to date and leaves me not choosing to try and reapply the update of the firmware (as is obviously what is happening through the touchscreen menu has already done).

    Should I just restore to factory settings? I think that firmware would not be changed by doing this. It is not an older version of the firmware available on the product support page, to return to an earlier version.

    Via the screen menu touch printer, a Printer Status Report print indicates the firmware version is MPM3CN1322DR.

    How to force a reinstallation of the firmware, or let them difficulty firmware which was released on 25-06 - 2013?

    I've been using Google Chrome and even had 2 tabs open in the same window, one from before the update and the second I opened after the update, so this was not a factor.

    I had not revisited the web interface of the printer to date, and currently, I see that the problem has disappeared!
    The version of the firmware has not changed, and I did no manipulation of the printer. I also highly doubt that the main user has nothing, because it is not tech savvy. So, the problem seems to have corrected itself.

    The only thing I see now, that I did not notice before, is that there is a version of firmware fix, but it currently says 0. I don't know what it was before, but I guess zero means that there is a patch, so the firmware didn't automatically update in order to make the problem disappears.

    Problem disappeared, but I don't know how or why. I haven't decided if I will update the second printer that is the same model.

  • M600 No. Web Interface after update to 1.11 to 1.65 iDRAC

    Hello!

    We have a few M600s which have not been updated for a while and are still ongoing iDRAC 1.11. When we update to 1.65 that they do not always have a Web Interface like some of our other M600s which have been maintained over the years. Looking at the scans Nmap and Wireshark, it seems that port 443 is blocked even if it is defined by default in cfgRacTuning. We tried to reset the newspapers, configuration and adjustment of different ports but not luck.

    We run CentOS 6.6 on these blades, and our upgrade method uses the file .bin on the Dell site. I was wondering if there may be another method of upgrading for those with them running old firmware.

    Thank you

    Stevie

    Found the solution.

    Looks like there's an old bug where when downloading a cert Active Directory it would replace the Dell SSL cert and we had a few old m600s that never have been set. To return to the original self-signed cert Dell iDRAC firmware must be 1.11 and run "racadm racresetcfg." All the foregoing 1.11 does not seem to reset the cert.

    The other solution is to download a signed CA certificate.

  • Printer HP LaserJet P1606dn Professional after firmware update

    Hello!

    I upgraded my HP LaserJet P1606dn Professional today the latest version of the firmware 20110826, of 20101011.

    Everything worked perfectly with the old firmware, but after the upgrade I can't print via network, although it works with USB printing.

    I printed a page of device configuration, and everything is as it was with the old one, which happens to me from printing, except his status in the network information section, which is 'boot' instead of 'connected '.

    I can't access the web interface via my browser by typing the IP address that is provided in the device configuration page (which is the same as the old, btw)... no idea?

    I also tried printing as well as access to content the printer via the web from different computers on my network, one with Ubuntu, another with Windows XP, and both get the same problems.

    Thank you!

    Hello!

    I finally solved it, the problem was the setting of DNS which has been reset when the upgrade of the firmware. I followed the following steps:

    -Reset the configuration of the printer

    -Connect to the web interface printer with the IP address the printer automatically sets to himself

    -Change all configuration, including DNS

  • OfficeJet Pro 8620e ADF jam error after firmware update

    After you install the updated firmware from the touch screen of the printer, the printer restarts and now has an error that says "Original is caught in the ADF (ADF).  Open the cover of the ADF, remove and reload the original, then try again. »

    I went through all the steps to clear a jam from the ADF, but the opinion is persistent.  It is not (and was not before the upgrade) in the ADF at all.  Since this coincided with the update of the firmware, my suspiscion is that the firmware has not installed properly or something.  What am I doing here?

    This problem has been resolved using the printer instead of purchase and exchange for another.  I can hardly believe that the cables are working loose within two weeks, she was detained and then broke at the exact time that the firmware update has been completed.  In any case, the problem was solved by replacing the printer.  I don't have any feedback solutions until a month after I did.

  • SOLVED: Slow wireless internet passthrough after firmware update

    If I first bought a Nighthawk in July 2014 and it was great for a while. Then in the notice happened a few months my streaming services are jumping and more than usual buffering (which was almost never with the Nighthawk).

    I have a connection of 110Mbps (Comcast and through a SB6141 modem), but all of a sudden was only getting 10 Mbps (or less) passthrough on 5 G wireless band (at the beginning of the speed test would sometimes up to 50 Mbit/s, but on a few seconds would fall to nothing..)

    Cable speeds were very good. Always 110Mbps +. Tried several different channels and factory reset the router, wireless speed was still slow. Connected to the Netgear website and submitted a support ticket within 2 hours they sent me with an RMA number and the next day a new unit has been FedEx would be for me. Support rep Tech says it's a problem of material known in some units... I was super impressed with the customer service, it was seriously a no replacement of hassles that took every 15 minutes of my time.

    EXCEPT when I got the replacement router in the next few days, he had the SAME PROBLEM. As soon as the new router is on and I'm connected, I've upgraded to the latest version of the firmware, done a factory reset and down Speedtest. And I had the same problem: speed internet passthrough on all my wireless devices has been terrible. Less than 10 Mbps when I have a connection 110 + Mbps. (Wired speeds were great, it was not a problem of modem or provider).

    Again contacted support and they asked me to download the latest firmware on laptop and upgrade the router manually, do a factory reset before and after the upgrade. They also told me to try to disable WMM (made no difference speed passthrough, but lower my laptop connection between 433Mbps to 54Mbps speed!).

    I tried this... still slow passthough wireless speed.

    The only thing that has changed since I first got a Nighthawk in July 2014 (and I've run speedtests then and had a speed 110 wireless + Mbit/s at the time), is that the firmware has updated several times... makes me think...

    I downloaded the Netgear support the past 5 versions of the firmware for the Nighthawk. http://downloadcenter.netgear.com/en/product/R7000#sear...

    I then manually downgraded the Nighthawk to each previous version (do a factory reset before and after each installation) and ran Speedtest every time. Once I have got down to the R7000 Version - V1.0.3.24_1.1.20 (released 12/02/14) and ran a Speedtest, the PROBLEM has BEEN RESOLVED. Speed wireless devices (laptop, HTC a M7 and iPad Air 2) were all back up to 110Mbps or more!

    Hope this experience helps someone else... If your are affected by the passthrough slow internet speeds and it is not your connection speed (i.e. radio parasites) that is the question, there seems to be a serious problem with the latest latest versions of couple... Try downgrading to the R7000 firmware version - V1.0.3.24_1.1.20

    UPDATE: Yes, I actually tested the speed with several different devices (a laptop HP HTC a M7 and Nexus 9) each on 5G band, all compatible with the latest updates ac. I also used a few test sites of different speed (speedtest.net, comcast speedtest, cnet speed test), not had the same result all devices and hosts.

    However, I actually got in touch with Netgear L2 support for the last month... beta test a few different versions of the firmware of the Nighthawk and even spend more than an hour on the phone one night with a nice guy who told me he was on an island in Southeast Asia, part of the Philippines... This is where Netgear technical support is to halfway between China where they build them and Taiwan where engineers are. After trying all tweak he could think for an hour and not get better speeds wireless, he finally dropped out and wished me a Merry Christmas lol. Not one of these beta firmware made a bit of difference, and I hate the hours that they made me screwing around with them!

    BUT today, they released vR7000 - V1.0.4.14_1.1.50 http://support.netgear.com/product/r7000

    And to my surprise it actually worked! Not only my high speed wireless is returned (120 + Mbps)

    http://www.Speedtest.NET/my-result/4078979293 (laptop)
    http://www.Speedtest.NET/my-result/a/1131321713 (nexus 9)
    http://www.Speedtest.NET/my-result/a/1131332778 (htc a m7)

    but also my Seagate SRD0SD0 previously incompatible (3 TB) USB 3.0 external hard drive works now, too. What a bonus! The reason I bought the Nighthawk was to use as Server DLNA and the monster external HD I picked up 6 months ago only was on the long list of those incompatible with this capricious router.

    But now everything works (at least for now).

    P.S. Maybe it's in my head, but I swear to you that since the last firmware update when running speedtest now or file transfer (while heavy streaming) I can hear the router doing a greater slope electric buzzing/hissing noise is a little disconcerting... I'm not sure my brain fried by overclocked wifi will be worth a high speed in the end...: eek:

  • Sansa Fuze - insufficient volume after firmware update

    After the latest firmware update to its maximum volume looks like a whisper. And the configuration of the System Volume option disappeared! Thought that this setting is set to Normal and should change at the top. But the Volume option no longer exists. I use the same set of headphones. Any ideas? Can I go back to the previous firmware? or should I get another MP3 player? Whenever I update the firmware, I have all sorts of problems! All the presets radio disappear as well! But the problem of volume is the most boring... Thank you all in advance.

    Why throw the baby out with the bath water?  Let build .31 on the device and set your locale.  Choose reset to factory settings, choose in North America and your preferred language.  For Europe, you will need to do is choose "rest" for your steps of FM frequencies.

    Note: You can leave the current version of the firmware installed on the device (build current est.31 ou.33 according to the revision of your device).  Once you select 'Yes' for the mask to reset factory settings, the unit will ask you your desired area.  For the EMEA region, do not forget to go to settings > Options Radio > region and select Europe for the stages of EU frequeqncy.

    I just wanted you to save a lot of hassle!  Your volume option will be available again.

    With regard to the volume, please use good judgment when you listen to your music.  Keep the volume at a reasonable level, because your audience in the long term is much more valuable than a little loud music.  If the device is for the kids, well, as a dad, I know how they are.  Perhaps the limited volume can be useful for once.  You can blame on the EU regulations.

  • PC now does not see files on the rocket after firmware update

    Until I updated the firmware to v01.02.31P, whenever I plugged my rocket to my PC (Windows XP), it was considered to be a separate drive (e.g., F in Windows Explorer - "Devices with removable storage" and I had no problem using drag & drop, delete files, etc. and download podcasts on Web sites.) Since I've updated the firmware, every time that the rocket is connected to the PC it is now considered rather camera phone in Explorer Windows in 'My Computer' with internal and external memory card uSD

    However, all my existing music files are not 'seen' - for example i.e. the files are now shown as empty, even if the 'properties' of the internal memory shows significant used space and Windows Explorer can't see the files I put on the "rocket".

    Anyone can help getting Windows to 'see' my music files, or is it possible to roll back the firmware.

    Thank you

    The firmware update reset the USB MTP mode or detection automatic (it was before MSC mode). Files transferred in a mode are 'invisible' to your computer when it is connected to the other mode, as you have discovered.

    Just go to settings > USB Mode and she return to MSC if you prefer the way things were before.

  • WRT 160N V3 - signal drops after Firmware update

    Hi I recently upgraded the firmware on my wrt 160N v3 and changed security WPA2 Personal wireless from WEP (I needed to do this to get the speeds of a purchased wireless adapter recently).  Now the router stops transmitting a signal intermittently for about a minute before returning to the line.  The time between drops is also not the same.  Before updating firmware (and change security settings), the router has been solid as a rock.  Any suggestions on how to fix or maybe where I can get the old firmware version (which seems to be more stable than the current version)? THX

    You mentioned in your post that you updated the firmware. So, after firmware upgrade reset you the router? After the successful update, you need to reset the router. It is recommended to reset the router once. Steps to reset the router:

    Press the reset button on the router for 30 seconds, turn off the router, wait 30 seconds and then turn it on. Power light should blink when you perform the reset process.

    After reset, reconfigure the router, and then check the status of the connectivity.

    If the issue still persist then yry the following parameters:

    # Open the browser and in the address bar type 192.168.1.1 which will open the router configuration page.

    # Bring back the MTU (Maximum Transmission Unit) of 1500 to 1400 or less (usually found on the main page / basic configuration of your router). Here is the link to determine and implement the right size MTU: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=fbf8e8564632422eaa8ea80bf9dcba64_386.xml&pid=80&re...
