GS748TS web interface issue when configuring LAGs

GS748TS web interface issue when configuring LAGs

We have several GS748TS which need reconfiguration of the LAGs, however neither Chrome nor IE 10 (both normal and compatibility mode) appear to allow us to access the LAG configuration.

In Google Chrome, everything loads, except for the UI component to select ports to add / remove from a lag (Switching -> LAG -> LAG Membership). The same occurs for VLAN membership.

In Internet Explorer 10, the initial page after login doesn't even load correctly. With compatibility mode enabled, clicking on Switching -> LAG doesn't show the summary of the LAGs, however VLAN membership configuration works fine.

Any suggestions as to how we can manage the LAG configuration? A new firmware would be nice 🙂

Switch specifics from System -> Management -> System Information:

Model: GS748TS
Hardware Version: 00.00.01
Boot Version: 1.0.1.5
Software Version: V5.2.0.10

Re: GS748TS web interface issue when configuring LAGs

Further searching, and in parallel NetGear Tech Support, pointed me to this KB:

http://kb.netgear.com/app/answers/detail/a_id/23841

I wonder how much time in aggregate has been wasted by how many NetGear customers like us since NetGear first knew of this issue? And they didn't even bother to update the docs, or include an Errata / Read This First slip?

Jeez, what an attitude.

Re: GS748TS web interface issue when configuring LAGs

Have you tried firefox?

If you still have an issues contact support directly with it via portal at my.netgear.com

If interface is orange/blue then seems I have just read last week different model with orange/blue interface has browser issues

Re: GS748TS web interface issue when configuring LAGs

Hi

Has this ever been resolved, I have inherited a site with a number of these switches and need to configure some LAG and VLAN's.
(or I need to throw the switches away)

Re: GS748TS web interface issue when configuring LAGs

Same here. Wasted several fraught hours this weekend, assuming there was a problem with my client's servers, or a failure of one or more of three GS748TSes we've just bought.

This doesn't feel like "browser issues".

I've tried IE, Chrome, and Firefox. Repeating the same operation on the same PC/browser yields inconsistent results. Of the hundred and more times I have tried, once - yes ONCE - I saw the correct LAG membership page. Often I don't even get past the password - just the top part of the screen refreshes - sometimes after a delay, the rest paints in. Same for other screens thereafter.

This even on a completely silent network, two devices attached to one switch, immediately after a factory reset.

Hardware / boot / firmware: 00.00.01 / 1.0.2.0 / V5.2.0.9

NOT A HAPPY BUNNY !

I am having the same problem. Wasted several hours on this.

Hardware/Boot/Firmware versions:
00.00.01 1.0.1.5 V5.2.0.10

Has anyone got any hard information from Netgear?

Also NOT happy

Re: GS748TS web interface issue when configuring LAGs

Count me in for 5 lost hours on this. Mine was actually trying to change the VLAN membership of the ports, but in Chrome the bottom half of the screen would never load. In IE, almost nothing at all would load. Netgear has the WORST tech support. I don't understand how a company can fully expect a customer, setting up a brand new device, to waste hours trying to find a solution to a problem. that seems to be totally acceptable to Netgear and would not fly in any other business!

Re: GS748TS web interface issue when configuring LAGs

Thank you so much for posting the link !!! WIthout that, I was thinking I had a bad batch of netgear switches. How is it possible that the only web browser software that will display this right is over 4 years old??? That is incredibly unbelievable!

Re: GS748TS web interface issue when configuring LAGs

I have downloaded FireFox 3.5.6, but when I try to log into the switch, I get the following message.

The page at http://192.168.0.239 says: There is no response from the server.

I can't even get logged in with FireFox. Can anyone verify what has worked for them?

Thanks.

Thank you HM for that link

Firefox Portable 3.5.6 works for me.

This should be in big letters in the manual (or preferably the firmware fixed).

A reason not to buy Netgear in the future.

Re: GS748TS web interface issue when configuring LAGs

This is strange, I am using Chrome 33 and IE 11.0.3 and see everything on the LAG and VLAN screens. I am having a VLAN issue related to the actual traffic behavior, which is what brought me through this thread, but after checking against those two and Firefox 3.5.6 all the ports and their config states show up with no problems.

Re: GS748TS web interface issue when configuring LAGs

This has cost me hours until I found a reference somewhere else pointing into the direction of an old Firefox. BTW: you can use Firefox Portable 19.x.y as well, it'll work.

The NetGear webinterface is completely in javascript and somwhere in processing the result something goes wrong. I had a case open with an engineer who came up with 3.5.6 as well (but I already knew). I have complained that a switch that is still sold is no longer manageable with a normal browser. First response: this switch is EOL, see our list. So I glanced at the list and said: but hey, here is a strange thing... the switch might be EOL but it is also advertised as a switch that is a replacement for another type that is EOL. That is a bit confusing for your dearly appreciated customer.

The last rumour I heard is that a maintenance update for the firmware is being considered to solve this issue.

Re: GS748TS web interface issue when configuring LAGs

Hi All,

I used to be able to configure it using Chromium Browser from a Linux box (Lubuntu 12.10), but it didn't work for me today (latest Chrome from Linux Mint 17).

Luckily I was able to configure it while using Safari browser on Mac which is not an option for many people, but possibly Safari on Windows will work as well. Also, some but not all problematic features of the interface were configurable from default Android browser on my ASUS TF701T tablet.

Hope it will help.

PS: Update to 5.0.10 firmware does not solve the problem.

Re: GS748TS web interface issue when configuring LAGs

I confirm that the latest Safari for Windows ( v.5.1.7) allows accessing all features of the web interface.

Re: GS748TS web interface issue when configuring LAGs

Hit by this issue too.

This is definitely a ProSafe "Lifetime Warranty" issue since it is no longer possible to configure the hardware.

For sites with policies mandating specific application versions Netgear's suggestion in Support answer 238341 to use an obselete browser is not a solution.

I consider it unacceptable that Netgear's recommended 'solution' is to use an unsupported, insecure, web browser, instead if simply fixing the Javascript bugs in the web interface and pushing out a firmware upgrade.

Expecting them to push out a firmware fix for this is unlikely. Download an older version of Lightweight Portable Security (which has a built-in browser) and use that to configure it. Free easy workaround.

Speaks volumes to Netgear's lack of serious support for ProSafe though.

As to fixing it, I've already re-written part of the code so it works, as a proof-of-concept that I can successful write and install my own firmware images. If I can do that, then Netgear can for sure.

It does, but unfortunately this is common for any of the smb router manufacturers. (I've seen this with Cisco rv series as well).

That is awesome that you can write the firmware changes yourself! Please share! I'm sure others would love to your version of firmware.

I will make sure the process is bullet-proof before I publish the details since I don't want other, probaby non-technical, folks bricking their devices! It will require use of specialised tooling on a Linux workstation.

I can't simply publish firmware images since, unless *everything* is re-written from scratch, it would infringe on the Netgear copyright - unless other device operators want to cooperate on an opne-source implementation 🙂

I agree, although if they mess up, it's their own fault. The consumer side of third-party router firmwares has already sorted out that liability.

True, unless Netgear has used open source in their code. Also, you could just provide a custom service that someone needs to contact you--this way you control the distribution.

As promised, the first half (extractor) of my ROS firmware toolkit is available. I've announced it in its own thread in these forums. Please test and provide feedback.

Thank you for the release! I'm not well versed in linux, but if it's something pre-compiled, I might be able to give it a go.

Re: GS748TS web interface issue when configuring LAGs

It is ridiculous they won't fix this.

I wonder if there is a possibility to provide a user fix via something like Tampermonkey, rather than reflashing the firmware.

Cheers,

Keith
