Problem with Huawei MT841

I have a Huawei Smartax MT841 which I am using for couple of years now. Off-late it is behaving very strangely, it so happens that whenever modem is restarted with PCMIA card in the modem slot the modem would keep rebooting endlessly. However if I remove the card and boot it with LAN cable connected then the modem would work normally. Now the interesting thing is if I log on to the Modems' index page (using 192.168.1.1) and press save all button, with PCMIA card in the modem slot then, at times it would boot just fine. However this does not happens always.
Few things I would like to add are
1. I have never updated my firmware, as I reckon it cannot be a firmware issue (as modem does boots up at times)
2. This is always happens after the restoration of power (as modem is connected to inverter and it restarts when power is restored.
3. When I try to hard reset my modem using reset button, it doesn't changes anything, i.e; it doesn't resets modem.
4. I read in one of the posts somewhere that it could be because of the condenser of the power supply (12V DC). However on changing the power supply the issue still persists.
Can anyone help me in this respect?

If you don't need WIFI from the modem/router,
to use laptop in WIFI mode without any cable connection ( RJ45) , need not use the card.
Upload as screen shot Jpg picture shot the summary page, at say tinypic.com and give the link here. ( as hxxp://xxxxxx)
Or use the Annexure option here.
Mod mode if GDMT may result in a stable connection.
To save all settings go to Management/Maintenance and CLICK the SAVE Reboot button there.
Wait for two or three minutes.

I am sorry but I am not able to understand what do you mean by this, I do need WIFI from the modem/router, but I am not able to do it since modem won't boot with WIFI Card in the modem. I am not using PCMIA card in my laptop. For the sake of further clarification the Huawei MT841 router needs PCMIA card inserted in the slot provided in the modem. As for the RJ45 cable, I am using it since I am not able to use my modem in WIFI mode. However the modem works fine when PCMIA card is removed from the slot and modem is rebooted.
