Recently my Vario II intermittenly loses network signals, it says No Network and I have to toggle phone off/on to make it search for signal again. This only happens when I'm at home (Charlton SE7 area).
Rom 1.21.110.3 (19/06/06)
Radio 1.05.05.00
Does anyone have the same problem?

Flash HardSPL first, then upgrade your radio.
Ive linked to my guides incase your unfamiliar with the process.
The newer radio should possibly increase your GSM efficiency. Are you in a decent area for reception?

Hi, many thanks for your detailed guides. I've upgraded Radio to 1.38.00.10 but the problem still persists. I'm in a very good coverage area, always get full bars 3G when it works. Soft-reset my phone and now it's searching in vain for network signal, I'm confused
What operator are you with ? Maybe the cell where you live is getting overloaded. We had a problem similiar to this last month when our local base station had a problem. Our work-around was to disable 3G but not using a Hermes . Apparently the handset tries to register using the 'best' data-bearer its configured for. So disabling 3G made it register with GPRS which worked fine. They then fixed the base station and we were able to re-enable 3G. I would
guess Charlton would have a lot of subscribers per cell. You would expect the coverage to be better in a built-up areas but who knows. Maybe an enquiry/ complaint to the operator would at least tell you if they know of a problem and if its temporary or longer term
Cheers for that. I'm with T-Mobile. What's bugging me is that this signal disappearance only happens sometimes. It's not that I don't have 3G (or signal for that matter) at all, I still get full 3G signals fine most of the time. But you probably were right, looks like it's a fault from the operator's cell in the area, I will give them a call next week to see if there's an explanation.
I've noticed this problem when I'm in the south London area (very general I know). People have got around the issue temporarily by forcing the phone to GPRS only
More problems! After upgrading to 1.38 and trying all sort of "good" radios like 1.17, 1.27, 1.34 I can't make/receive calls unless GSM is forced. There must be something wrong within my immediate area because with the same radios everything works flawless just 10 mins down the road. I just called TMob and there's no technical fault or anything from their side. I will just have to put up without 3G until the problem fixes itself
There are lots of people complaining about 3g on T mobile in UK. They seem to have serious issues with Hermes devices and the dropdown to GSM.
I had a problem six months ago with my hermes on orange at home in SW London. For a few weeks it was mucking about - I rang O who advised me that they were experiencing some local issues but would fix them within days. I switched to GSM for a few days. When I switched back its worked fine for last five months.
3G gone mad!
the same thing was happening to me. Full 3G reception in Leicester, tried to connect to get my e-mails and then the signal totally goes. The same thing happens when I make calls as well. Switched to GSM and everything worked. Now in York and everything is working on 3G.
Network is T-Mobile.
This sounds similar to the issues I am having.
Do you get the phone hanging as it attempts to start a call and then after a while a message stating that it was unable to connect?....sometimes resulting in a soft reset to bring the device back online? In my case toggling bluetooth will reset the connection.
I am with T-Mobile in Glasgow but get the same issues during the day in Edinburgh
No 3G

No mine doesn't say anything, it sounds "ding ding" after a few secs like when you press the hang up button. I can use the Internet but anything to do with calls is just impossible. I've switch to GSM now and everything's back to normal. A bit annoying can't use 3G at home.
I recently moved into a new ‘cell phone death trap’ apartment (apt).
I’ve seen my phone connect, I’m guessing; connect to four different cell towers from my apt. I’ve sat and watched it go from 2 bar E, disconnect, to 1 bar G, disconnect, to no bars 3G, disconnect, and so on….
But here’s the clincher…
Sometimes it will also connect to a full strength edge network, but it indicates it’s roaming by the Triangle icon. Now if I’m on that ‘Triangle” network, my phone works great, meaning I actually can make and receive calls!
But, I’m guessing again, because it shows it is roaming; it also does not like to stay connected to this network. Actually it prefers to switch itself back onto a weak edge network without any signal.
My phone battery doesn’t last more than five hours, NOT TALKING, just in standby because it is constantly switching towers.
At this point I want to throw my Hermes out a window! But I know that wont do any good, because anyone else who come to my apt and has AT&T/Cingular gets the same results.
So here’s my question:
“Can I force my phone to stay on a particular cell tower?”
If so, I love you….
you should re-post over in this thread Daniel's software might be able to solve your problem (or Daniel might have other ideas).
thank you for the suggestion. i tried that and he said, "Sorry nop. It isnt the pourpose of cmp or bs...."
I don't think you can force to a specific tower but you can force to a particular provider:
START/SETTINGS/PHONE/NETWORK/MANUAL
and also select whether you want to force GSM/WCDMA and the GSM/UNTS band:
START/SETTINGS/PHONE/BAND
Maybe by going this route you can lock onto a reasonable signal.
2 other alternatives... Sell the appartment... Buy a landline and donate the Hermes to me

Are you able to change networks?
Are you able to ask your service provider the location of the towers and if they're planning either any upgrades or any more in the area?
If not you may wish to consider the first point, changing service providers.
I know what a pain it can be to have little or no service when needed. Personally, here in the UK, I'm on Orange. Where I lived in Wales it was either Orange or Vodafone that has a decent signal. When I'm out and about with work those are the two popular towers with o2 creeping up and some others too, but for the most part those are the strongest.
I don't, I'm sorry, have any better advice for you. Apart from leave your Hermes on charge when you're home near a window (safely) and carry a bluetooth earpeice around instead Good Luck with your Valiant Quest

I've tried this method as well and it does not help. apparently both the good and the band networks all fall under GSM(900+1800)+UMTS(2100). The other two band options never find a network.

Thank you for your suggestions. Unfortuantly im locked in a 2yr contract, thats how ****ty american cell phone companies do things. Plus, the better providers in the area dont use SIM cards (ie. Sprint/Verizon), so that would mean bye bye Hermes.
Ill will go by the Cingular store and ask about the possible service upgrade, but those fools dont really know whats what, thats why im on xda-dev!
I like the bluetooth idea, ill try find a "sweet spot" in the apt and try that method. Thanks again!
"I have dream..."
My idea just seems possible, however i cant program so who am i too.....
The idea of having blocked cell id numbers. If i could FieldTest or somehow extract the cell ids from the towers i dont want, then create a file that the phone checks against before joining a tower.....
I dont know, just a dream i suppose...
In both cases (roaming and not) are you registered in same operator?
If you're having a difficult time maintaining solid cellular reception, you might want to consider buying an external antenna. Refer to my post here regarding an antenna that can be purchased from Radio Shack. The antenna is now on clearance for $20 and the pigtail is $10. This may or may not help depending upon your location in relation to the towers, but if you try it out, let me know how it works.
Cheers
Yeah, I'm on an 18 month contract... But I'm about 8 months in now
You might even be able to get bluetooth repeaters once you find your, ahem, sweet spot

i believe so. the only reason i think it's roaming is because of the Triangle icon. But my SIM is only authorized for one operator, Cingular.
is there a better way to check?
Thank you very much Daniel!

i would be willing to try those products but i believe they're now fully discontinued. Either of those item numbers from your post no longer exsist.

Call your closest Radio Shack and ask if they have either of those catalog numbers in stock. Worst case scenario is that they won't, however they can check the districts perpetual stock and see how many are available, and if you ask nicely, they can have the antenna and pigtail shipped to their store so you don't have to run all over creation just to get it.
...An even worst case scenario would be if you didn't live in the US or didn't have any Radio Shacks close by.. however I might know of someone who could use their employee discount to cover shipping costs Let me know if you have any questions.

Taze,
I would also recommend that you try one of Daniel's applications - he is working on Comm Manager Pro but I think that Bandswitch will probably help you. I find similar problems to those you describe at work here in the UK with T-Mobile and my battery would often run low even during a day at work. The problem appears to have been caused by the Vario II (Hermes) spending all day jumping back and forward between networks whilst hunting for the best signal. Although the Bandswitch application (very small footprint) will not increase the signal you may find that forcing the phone to operate in a particular band helps - this is very easily achieved via the Bandswitch interface rather than going into settings each time. I now regularly switch to GSM each day when I get to work and it has solved my battery run-down issue completely!
Comm Manager Pro does much the same and more. It allows you to define a location (according to Cell ID and LAC Code) from which you can set the CMP application to (amongst other functions) switch to a particular band - or even turn the phone off).
Given what you have said this may not help but I would certainly give it a go. Good luck.
Regards

im going to try bandswitch today and see how it works. thank you for the suggestion!
i wish daniel could add the feature of blocked, preferred, of locked Cell ID's. that would be worth a good amount of money to me....
Hi.
I would like to help you.... I can detect cells and lac but I cant force radio hardware to attach on a particular cell. This a task for Radio ROM. The only posibility (maybe) would be if the operator names are diferent. Could you go to settings a search for operators? Maybe your operator has different name in roaming than non roaming. In that case It would be easy to help you....
Oooo if FieldTest were a controllable application....
Ok what I’ve discovered so far after watching FieldTest for about an hour.
The Good Connection -
LAC 0020
MNC/MCC 31017
NCELL INFO1 700-80 dbm <---- (at least four out of six NCELL maintain a steady 700-80dbm, often all six NCELL)
NCELL INFO2 700-80 dbm
NCELL INFO3 700-80 dbm
NCELL INFO4 700-80 dbm
NCELL INFO5 700-80 dbm
NCELL INFO6 700-80 dbm
BAND 2CS
CHANNEL 1:CCCH (stays, doesn’t change)
The Bad Connection
LAC d6ef
MNC/MCC 31380
NCELL INFO1 140-100 dbm
NCELL INFO2 140-100 dbm <---- (i get two NCELL at the most 140 each, rarely four NCELL, never more)
NCELL INFO3 0
NCELL INFO4 0
NCELL INFO5 0
NCELL INFO6 0
BAND 3:850 (once I saw it switch to PCS on this same MNC)
CHANNEL 1:CCCH/0:BCCH/255<UNKNOWN> (switches between these quite frequently)
So what I’ve interpreted from all that is.
Well I’ve confirmed my ****ty connection. Even though the phone often shows two bars, I can’t make or receive calls. Based on the NCELL db numbers and the constant channel changing, that **** just don’t work.
Most importantly, the phone is always trying to switch to the highest possible band. Because PCS is a lower band than GSM 850, my phone won’t stay on the PCS connection.
O yes, another discovery is, in WM6, if you are connected to a PCS band network, it displays the Triangle icon as if you are roaming but in fact it is not roaming.
So Daniel since you seem to be the best chance for a better life [for my Hermes]:
I need a way to force band selection beyond just GSM and UMTS.
I tried BandSwitch and it does not work for me because all my available connections fall under GSM.
And even beyond that I’d like to be able to force MNC’s, as I believe they are the specific network number.
Or can I block a LAC?
In settings, I only have one operator, Cingular, “Home of the most dropped calls.”
Hi.
I undestand perfectly your frustration and I will try to do what I can althought It doesnt seem easy thing because there isnt any(known) api to manage Radio Rom. Fieldtest is OEM dependent and I imagine It only works for only one manufacturer of radio hardware chip.
Ok, first try. If you start radio phone 10 times....
1) how many times your phone register to roaming (and wished) network?
2) If registed to roaming network, how much time (aprox) stays on it before register to bad cells?.
Why? well ,CMP executes actions when you enter on some place (compound by cells and lacs). You could create a place with your hated cells and then associate the action "reset radio" when registed to those cells (or lacs). In this way if your device falls into bad cells it would be resetted (only radio, not phone) until registed to good cells...
Only an idea....
Dani
If you can determine the direction of the "bad" towers, try lining your walls with lead sheets to block their signals and letting you connect to a prefered tower.
I had purchased a second hand o2 xda neo. It had wm 5 on it . I updates it with wm 6.1 roms available here.I find that the gsm reception is very poor inside my home.I dont know whether this happened after the update. In my office it is quite good. Even when I am outside i have no problem. Only in my home the signal is very weak. can this be corrected by some registry tweaks or some software. or is it a hardware problem. and if so can i get it repaired. pls help...
what rom are you using and what radio was recommended for use with it. Sounds like a radio issue to me but plz tell me rom and radio. you can experiment using different radios found on the wiki to see whatworks best.
you can flash different radios without loosing data on the device.
I have tried with 2.19, 2.47, 2.69 roms. but no effect. I am trying today 2.07 let me see if that helps. Does IPL/SPL effect the singnal strength?
mmm it might be just one of those things, in that there is interferance within your house (my house is made from granite so reception is very poor), if recpetion is good elsewhere it is unlikely to be radio.
Is there 3G network there? The quality of service on 3G can be unpredictable at best of times.
Signal is not effected by IPL/SPL to my knowledge.
The results of 2.07.20 radio rom. It shows good signal but i feel that it does not update it when the signal is poor. In my office signal is good. So it showed full strength. I went home. There too it showed full strength. when i did soft rest to clear my doubt the signal was poor as in previous roms. Do you think that the antenna has some problem. Can it be replaced. i find an opening above the mirror( near the camers lens) for car antenna. Can this help? if so how?. 3G network is not available in my country(INDIA)
hey,
i think u might have to accept that the signal is just crap in your house... a bummer i know, but if youve tried various radios and signal is good elsewhere, it cant be the internal ariel.
have u tried flashing another rom, more recent build?
Not sure it will help but you never know... at the end of the day, signal is never constant in any one place.
But friend. The signal is good in other phones. If the signal is crap then it should affect other phones too.
I should have also said that the signal is never constant betwenn too phones in the same place. It depends on antenna hardware and the location of it, like signal is reduced whislt making a call if you place your hand and fingers in the wrong place.
I think it unlikely that is a hardware issue if your signal is fine in other areas. Sorry my friend i dont know what else to suggest having tried radios and roms.
The prophet is getting a little long in the tooth now, so be time for an update?
I had a quick search for HSDPA and connect to HSDPA but couldnt find a solution to this problem (if it is a problem...)
I get awesome reception with my phone. At home (in the sticks/country, quite far from another town or city) I get E reception usually 2 bars to full... this is connected to gprs or just on the phone with data connection turned off...
My problem is that when I head toward and am in London I get the H signal which holds for a few seconds at full strength then my phone seems to lose reception altogether and when recption returns its back to either E or G... I am hoping its something I am not doing in the settings or that H reception in London is generally not good... I have H enabled in the connection settings and data connections in advanced config... is there anything else I can do or should be doing...? Is H recption in London generally bad (any other experiences please let me know, perhaps a street in Central London where it might be great so I can go there and test my phones H reception, I go to Oxford circus at least 2 times a week or so)? Thanks in advance...
Thats O2 - I get alot of switching too, You dont seem to have move very far for the bars to go down when the H symbol is up, then you get an E and sometimes a G - I had this with my old phone too so I dont think it is the fault of the x1.
I dont think O2 3G/HSDPA network is very good.
I did hear that some carriers simply piggy backed their 3g stuff on top of their old 2g towers but 3g range is not so good so you get this switching problem until they add more towers.
Thanks Scote... that makes sense I guess but is a pain... I am going to try to get a replacement sim to see if that makes a difference as mine is about 4 years or more old now... much appreciated.
Ok this is just an update in case anyone else has a similar problem. I called O2 and asked them about it.. after a bit of transferring the lovely lady on the line tells me I have an older sim and need to get it replaced and to make my way to the nearest carphone warehouse shop (my account holder) and they will upgrade it for free... nice... so I am off to see the wizard, the wonderful wizard of 02...
Can't see how changing SIM would affect anything... sounds like she was telling you what you want to hear...
Have you tried flashing to the most recent radio per my sig?

Possibly, but its free so doesnt hurt to try... I have not flashed a new radio yet... will try it though if the sim doesnt work out... I gather the radios are in the ROM section of the x1 board?
try a new radio, i get it a lot and have the latest 02 sim.
also i think 3 (the network) is using o2 stuff so that might be why there 3g reception is not great.

Ok after transferring the new sim card into my phone I noticed that I could access edge in more places in my house where before I would get edge in the living room say and the study but not in the bedroom or kids play room for example and it was a stronger signal too... I went for a trip into one of the towns near my place (a 15 minute car journey) and the first thing I noticed when I went to make a call was that I had an H and all the bars were up. This was great as I didnt even realise that this town had HSDPA capability... woo hoo... so now the test will be on Monday when I go to London and see how it does.
FYI I did not flash a new radio just changed the SIM... apparantly (not sure how true this is) my old card was a 2g (I have had it for about 4 years or so) and this new one is a 3g which they tell me would make the difference... further updates to follow...
Ok I have a solution to this problem...
I phoned O2 and was put through to a customer services rep. I told them that my sim was a few years old (up to 4 or 5) and that it was not connecting to HSDPA services as it should, the lady said that my old card was a 2g and I needed a 3g card so she made a note on my account and told me to head down to the nearest CPW store and get a 3g replacement free of charge. I have NOT flashed a new radio yet... yet... perhaps later if their might be benefits to the new one... Almost immediately I noticed that the E service was stronger all over my house... I could get full bar service pretty much anywhere, where before I was getting 2 in most places. I even noticed H service in my living room which had never happened before...
Going into London today I noticed as soon as I got out of the car that I had full bar H service... and wow is it quick. I had it everywhere I went in Central London with the bars dropping to 2 when I was walking between some very tall buildings on Oxford st. So it looks like the sim card does have a direct impact on the ability to pick up a service... and I am just tickled as a pig in mud that its working full capacity...
I have radio version 1.10.25.18
I have not flashed the radio. Also have o2 3g sim
I noticed that although i have H a lot in 3g areas, but a lot of the time when i send texts / access the net it jump back down to E or G but will stay on H if left on standbye or if i receive texts / calls.
when i make calls it seems to stay on H but hard to tell as forget to look
I went through the forum and couldn't find any solution, so I decided to post it here and hoping for somebody to help:
There're 3 problems/issues:
1. The phone does not always show "H"(HSPA+) for data. It usually shows "3G", and when you try to access internet, after some 10 secs, it turns to "H". This is for when you are standing still in a location with good signal coverage.
2. When I'm in a moving car, the data speed gets really slow. Takes forever to load up xda for instance. Most of the time "3G" is shown. Sometimes "H"(HSPA+) appears for a random but generally short time period.
3. When moving out and in to Wind signal coverage, it takes very long for the phone to connect to Wind's service.
----------------------
Now don't tell me this is all because of Wind has bad signal, because if I put my sim card back to my old HTC amaze, none of the 3 issues above appears.
I know it's a known issue that Wind and Nexus 4 together has a problem, but I'm really looking for a solution to this as N4 is a really nice phone with Wind's unlimited data on it.
Someone help plz!!!!!!!:fingers-crossed::fingers-crossed::fingers-crossed:
-------------
BTW. I called Wind customer support today and they give me no helpful solutions. They also admit that although they are officially offering the Nexus 4, they have no custom tweak on the radio/modem of the phone.
------------
update: since the phone stays on 3G when there's no internet loading, it's probably saving battery this way. But with Wind's poor network, it's better to always be on "H".....is there a way to do that?
same problem
When we first got on WIND eaarlier this year we needed to get a new sim card to fix reception issues so you may wantt to see if that's part of your issue? Wife's Google Nexus 4 iwas purchased right form tehgoogle store and is not modded in any way.
I don't know if it's the area I'm in (Burlington near upper middle and bronte creek) but reception on the Wind network is spotty at best. And it almost seems as if form Jan. 2013 to now it's gotten worse at my house.
We have the same problem on my son's LG Optimus 4X HD as my wifes Google Nexus 4 so maybe it's just winds coverage in certain areas?
If there's any mod. I can do to improve the crappy signal from WIND I would love it because right now we are shopping for a different carrier due to the reception problems.
I had a friend using Solavei with similar issues. Tried a new SIM card, same issue.
Eventually got a replacement from Play Store, solved issue - was a defect in first phone. The Play Store has great support.
Details like which ROM/build would be helpful. Which modems you've tried, etc.
