Re: EA8500 Losing 2.4GHz Connection with latest 1.1.7.182977

It could be the firmware image storage location has a bad blocks and that's why reverting to the previous firmware resolves the issue.

To test this theory have the EA8500 running the
latest firmware and then manually upload the latest firmware again via the router's WebUI.

Unfortunately if this works then your EA8500 is defective and will need to be warranty RMA swapped by contacting linksyscares@linksys.com.

I have reproduced many firmware and hardware issues for Linksys forum users. You can find then in my posts across many forum threads.

I already tried that twice and still same problem.
Linksys product should only have a 1 year life written on the box . Very bad product. I advise all to buy a different brand.

Please confirm you downloaded the firmware file from the Linksys support site and uploaded that when the EA8500 was already running that same firmware.

Yes it took the newest firmware automatically and then I reset to factory and updated again manually

Have you used a free Wifi Analyzer app or software to see if the 2.4Ghz is having issues with outside wireless signals?

I did scan for best channels using apps . The thing is it was working without any issues until the latest firmware update.

Yes and since I tested it's not the firmware so the only thing left is a nand flash issue which is hardware related.

 

It would be more of a wide spread issue of the 2.4ghz dropping but not a lot of users reporting that. Maybe a lot of those users are able to RMA the router.

The router passed its one year warranty . I think Linksys should write 1 year hardware life on the box .

Re: EA8500 Losing 2.4GHz Connection with latest 1.1.7.182977

I have been reading about NAND chips and how they should work during programming cycle and i found out that most Nand chip will do CRC checksum at the end of the write or read cycle to inspect for any errors.

 

you said that if my router is on the latest firmweare and it accepoted the new firmware update manualy, it means it has a bad block on the NAND. accordign to my reading if the NAND chip have a bad block it would be impossible program it and the whole firmware upgrde should fail becuse the NANDA will fail the CRC check .

 

why would my router pop up a msg saying my router is updated sucsesfuly ?

 

at least linksys should elaborate in such isses

I am sorry to say it but all the new firmware for this router are pretty garbage.  I have had the EA8500 for over a year and when I bought it the thing was rock solid.  It went downhill after about 8 months and I have been fighting with it for at least the last 6.  I finally gave up and flashed back to a much earlier firmware and turned off auto updates and the thing has gone back to rock solid.  

 

The router itself is great but the firmware updates , at least for me, have been sketchy to say the least. 

 

*The wireless would drop...2.4 and 5ghz bands.

*Unresponsive GUI interface when connected to Linksys smart wifi resulting in a forced reset. 

*Internet speeds dropping to 1/3 of what it should be until the router was restarted. 

 

I have been back on the earliest firmware I could find which takes it back to about when I bought this router and it has been nothing but rock solid for weeks now. 

 

I don't necesarily recomend flashing backwards as it isn't the best plan and can brick things , but it is what helped me.
