SPWF01SA.11 firmware downgrade

Hello,

I wrote my software with SPWF01SA.11 Version 140805-3f58d6b
to use it as a mini-webserver linked to a wifi router (wifi_mode = 1, no dhcp).
My code is working well with this item.

Now, we received new modules SPWF01SA.11 Version 150410-c2e37a3
and the module do not work well. I upgraded one of them to Version 160129-c5bf5ce,
and my mini-webserver does not have a good behavior :
  - wifi connection seems OK (i get +WIND:24:Wifi Up)
but I can't ping my module from PC (or just a few seconds).
My module with 140805-3f58d6b is still working well.

First question :
  - where can I get version SPWF01S-140805-3f58d6b.OTA to downgrade the new modules (and is it a good idea ?) to check if my problem is well a version problem.
 
Second question:
Is it a problem of configuration ? I do not find,
the differences between my modules status and configuration are below :
STATUS
version = 140805-3f58d6b / 160129-c5bf5ce
wifi_aid = 3                        / 2
wifi_chan_activity2 = 0x00003FFF / 0x000001FFF
wifi_gf_mode = [absent] /  0
free_heap = 22928 / 18968
min_heap = 22376 / 17688

CONFIGURATION
etf_mode =  [absent] / 0
console1_delimiter = [absent] / 0x0000002C
console1_errs = [absent] / 1
wifi_txfail_thresh =  [absent] / 5
wifi_ht_mode =  [absent] / 0
wifi_region =  [absent] / 1
ip_wait_timeout =  [absent] / 12000
ip_sockd_timeout =  [absent] / 250
ip_dhcp_lease_time =  [absent] / 120
ip_dns_mode =  [absent] / 0
ip_use_cgis =  [absent] / 0x0000000F
ip_use_ssis =  [absent] / 0x0000000F
ip_use_decoder =  [absent] / 0x00000000

I also hav problem with ram, it seems I have less Ram with new versions (free_heap)
and maybe my webserver files go over Ram size with new version (I do not met the case
with Version 140805-3f58d6b).

Thank you for your help.
