Arcadia · Los Angeles County
Onsite and remote tech support across Arcadia — Downtown, Santa Anita, the Arboretum area, and the Baldwin Ave neighborhoods.
Arcadia is one of the most heavily Chinese-American cities in the country — nearly three in five residents are Asian American and close to half the city is of Chinese descent — which has earned it the nickname the "Chinese Beverly Hills." That shows up in our work: a lot of calls are multigenerational households where we're setting up devices, simplifying phones, and keeping reliable video calls going for parents and grandparents, often to family across the Pacific, while the Baldwin Avenue and downtown dining corridors are full of bilingual small shops and restaurants that depend on a POS and printer staying online. The housing is a mix of mid-century foothill homes and a wave of newer luxury rebuilds near the LA County Arboretum and along Baldwin Ave, while Santa Anita Park (the historic racetrack open since 1934) and the adjacent Shops at Santa Anita — the mall most people here still call Westfield Santa Anita, which is what it was named until it changed hands — anchor a big retail base. The practical catch in all of it is range: lots are large, walls are often plaster over chicken-wire, and Wi-Fi reach is the single most common reason we get called — worst in the Santa Anita, Highland Oaks, and Upper Rancho pockets where the back of the property never sees signal. What that last detail is really describing is the top of town. Arcadia's northern third does not fade into the next suburb — it ends at the Angeles National Forest, and the streets that give us the worst Wi-Fi are the same ones that run out at the tree line. Highland Oaks Drive climbs until it stops at the city's own Wilderness Park at the mouth of Big Santa Anita Canyon, with Chantry Flat Road switchbacking up into the forest from there, so the homes we work in up there sit on deep lots with detached garages, casitas, and gates a long way from the router — and on the wrong side of a fire line. In the January 2025 windstorm the Eaton Fire pushed its northeast edge toward Chantry Flat in the canyon above town, and Arcadia drew its evacuation map in street lines rather than neighborhoods: at the peak everything north of Orange Grove Avenue was under an evacuation order and the blocks north of the 210 were under a warning, and orders were not fully lifted until January 15. Unlike Pasadena and Glendale, which run their own city-owned electric utilities, Arcadia is Southern California Edison territory — during that storm the city was sending residents to Edison's outage map while crews chased downed lines. That is the part that reaches our schedule. Wind outages up here tend to be short and repeated rather than one long blackout, and short outages are what wreck equipment: drives corrupt mid-write, the modem comes back before the router does, and the far end of the property — the gate opener, the driveway camera, the garage mesh node — rejoins the network in whatever order it feels like, or not at all. So in the foothill streets we put a UPS on the desk and a second one on the modem and router, set cameras and hubs to reconnect on their own, and get the backup somewhere other than the house, because on the worst days here people leave with a laptop bag and not much else. There is one more thing that shapes the work in those streets, and it is procedural rather than technical, which is why it tends to surface on the morning the trench is meant to be dug. Five neighborhood associations in Arcadia are recognized by City Council resolution, and each one has an Architectural Review Board with architectural design review authority over its area: Arcadia Highlands, Rancho Santa Anita Property Owners, Santa Anita Oaks, Rancho Santa Anita Residents, and Santa Anita Village. Those are not small corners of the map. The Highlands association alone speaks for about 850 homes in the northeast section of the city — by its own description the ground north of Foothill Boulevard and east of Santa Anita out to the Whispering Pines ridge, developed mostly in the 1950s and 1960s — and that is the same ground as the Highland Oaks streets named further up this page as the worst Wi-Fi in town. The person reviewing your project is a volunteer neighbor appointed under the association's own bylaws with their name on file at City Hall, and the standards they apply are the city's: under the current resolution the board cannot invent its own. Before that sounds like an obstacle, the useful half is what it does not touch. The resolution states that the board does not review work taking place only inside a building that does not substantially change its outside appearance — so pulling Cat6 through the attic, adding a mesh node in the back bedroom, running the network over the coax that is already in the walls, and moving the equipment out of the entry closet are all simply yours to do. What crosses the line is the outdoor half, and on lots this size the outdoor half is very often the actual fix. The short-review application lists mechanical equipment, ground-mounted solar, fences and walls, detached accessory structures, and landscaping and hardscaping among its project types, and the exemption for low walls under two feet explicitly does not cover hardscape in the front or street-side yard. So a conduit run out to the casita, a small structure or cabinet for equipment at the back of the property, a generator or a mini-split cooling a hot equipment closet, and the post a new gate opener bolts to can all end up in front of a board. It is not a difficult process so much as one you have to leave room for: a short review is decided by the board chair within fourteen days of a complete application, the approval is good for twelve months, and there is a ten-day window in which the decision can be appealed. The practical advice is to put every exterior item into one submittal at the start of a project instead of discovering them halfway through, and to bring a drawing that shows where the conduit comes up and what the equipment looks like from the street. The notable exception runs the other way: a dish or antenna is largely out of reach of rules like these, because the federal over-the-air reception devices rule protects satellite dishes up to a meter across and the antennas that carry fixed wireless — a Starlink dish among them — against local and association restrictions alike. There is one more thing we deal with here more than anywhere else we work, and it comes from the top of this page rather than the top of the town. A household that takes regular calls from family in China, where a parent or grandparent handles things in Mandarin and is used to hearing from offices on the other side of the Pacific, is precisely the household one particular fraud is built for — and the people running it know that. The FBI has been warning about it publicly since a January 2024 advisory from its Internet Crime Complaint Center: criminals pose as Chinese police officers or as officials of the Ministry of Public Security, and in the bureau's own words they "typically use technology to mask or ‘spoof’ their true telephone numbers" so the call appears to come from a real agency or from the Chinese Embassy. They then produce paperwork — the FBI describes "fraudulent documentation, such as purported law enforcement credentials" alongside copies of the victim's own identification, and elsewhere "realistic-looking arrest warrants" — to convince the person that they are the subject of a financial-crime investigation back home. The ask at the end is money: the FBI says victims are instructed "to wire a large sum of money to a Chinese bank account to prove their innocence or to post bail." The step in the middle is the one that becomes our job, because it is a technology problem rather than a banking one. Before money is ever mentioned, the FBI says victims are pressured to "consent to 24/7 video and audio monitoring due to the alleged sensitivity of the investigation." In practice that means something installed on a phone or a laptop, a device left sitting on a video call for days, or a screen-sharing or remote-access tool set up so the "investigators" can watch. Whatever else it is, it is unauthorised access to a family's devices, and it does not pack up and leave when the caller finally hangs up. Cleaning that up is ordinary work: find and remove the remote-access and monitoring software, change the passwords from a device that was never part of the call, work through which accounts were signed in on the compromised machine rather than guessing, and switch on two-factor so an old saved session is not a permanent key to the house. Two things are worth saying to an older relative before any of this happens, because both are checkable in the moment and neither requires knowing anything about computers. The first is the FBI's own line that "contact from an apparently official phone number is not proof of official action" — caller ID is the easiest part of the whole call to fake, and it is usually the part that makes everything after it believable. The second ends the conversation on its own: the bureau states that "foreign government officials conducting legitimate law enforcement activity in the United States must act in coordination with US federal authorities." A police officer in China does not investigate someone in Arcadia by video call, and no real investigation of any kind is settled by wiring money to prove innocence. The rest of the advice is the FBI's first instruction — resist the pressure to act quickly — and the version that actually works in a family is a rule agreed in advance, while nobody is frightened: a call like this gets hung up on and called back on a number the family already had, and nobody moves money or installs anything on the strength of a phone call, in any language. There is one more camera question on these streets, and it runs the other way from every other sentence about cameras on this page, all of which quietly assume the camera is yours. On July 6, 2024 Arcadia police were called to the 1600 block of Oakwood Avenue about a suspicious device in a front yard, and what the homeowner had found in the bushes was a camera and its equipment, positioned — in the department's account — so that it was capturing other homes in the area rather than the house it was hidden at. Two findings from that examination are the ones worth carrying around. The camera had no internal storage, and a mobile hotspot was connected to it, so whatever it recorded left the street over a cellular connection rather than over anybody's Wi-Fi. Arcadia police put the pattern plainly: "Camouflaged cameras are a tactic being used in residential burglaries," and "suspects will place hidden cameras in areas where it allows them to gather information about neighborhoods and particular homeowners' daily routines." Take those two findings together and the usual advice about strange devices turns out to be the wrong advice here. When people worry that something has been put on their property, the instinct — and the instruction in most of what is written about it — is to open the router's admin page and look for an unfamiliar client on the network. A device carrying its own hotspot was never on your network, so there is nothing to find there and nothing to block. The check that actually works is physical and slightly boring, and it suits lots this size: walk the frontage and the property line, at the hedge, the mailbox post, the utility pedestal and the low garden wall, which on streets with this much landscaping are the only places with real cover, and look for anything with a fresh cable tie, a taped seam, or a housing that does not match what the utilities left behind. The other half is a placement decision rather than a purchase — point one of your own cameras at the approach to the property instead of aiming all of them at the front door, because the frontage is where a recording shows somebody setting a thing down, or coming back for it. California has since named the opposite problem. Signal jammers — the devices sold to knock wireless cameras and alarm sensors off the air — became a crime of their own when Senate Bill 701 was signed on October 7, 2025 and added Section 636.6 to the Penal Code. It defines a signal jammer as "a device that intentionally blocks, jams, or interferes with authorized radio or wireless communications", makes manufacturing, importing, marketing, purchasing, selling or operating one an infraction carrying up to $500 for a first offense and a misdemeanor for any offense after that, adds a separate misdemeanor for operating one while committing another crime, and requires the device to be forfeited on conviction. None of that changes what we install, but it does explain why the advice on these streets keeps landing in the same place — and it is the same place the wind outages already pointed. A camera that only exists while the link is up has a switch somebody else can reach. Recording kept locally as well as in the cloud, the runs out to the gate and the casita done on cable while the trench is already open rather than over radio, and an alert for when a camera stops reporting: that last one is usually the only reason anybody notices in time.

Free, plain-English help — whether or not you call us.
Onsite and remote — we come to you.
Often yes — call before noon for best chance of a same-day appointment. Otherwise we schedule next-day.
Yes — we cover the Santa Anita area, the Arboretum, and all of Arcadia. Most appointments are same-day or next-day.
Yes — that's one of our most common Arcadia calls. We set devices up to be simple and readable, get reliable video calls working (including international calls to family abroad), and write the steps down so they stick.
Yes. Temple City, Monrovia, Sierra Madre, and San Marino are all within our regular service area.
Absolutely. We diagnose where the problem actually is — modem, router, wiring, or the ISP — and only call the ISP if needed.
Yes, and it's a common call north of Foothill. We put battery backup on the modem and router so short Edison outages don't take the network down at all, fix the restart order so the router isn't coming up after everything else, set cameras, hubs, and gate openers to reconnect on their own, and make sure your backup lives somewhere other than the house.
Treat it as a compromised device, not just a bad phone call. The FBI has warned since January 2024 that criminals impersonate Chinese police and Ministry of Public Security officials, spoof the caller ID so it looks official, send fake credentials and realistic-looking arrest warrants, and pressure people into "24/7 video and audio monitoring" before money is ever mentioned. Whatever got installed is unauthorised access. We remove the remote-access and monitoring software, change passwords from a device that was never on the call, go through which accounts were signed in on that machine, and turn on two-factor. Two things from the FBI worth repeating to an older relative: an official-looking phone number is not proof of anything, and foreign officials cannot carry out law enforcement in the US except in coordination with US federal authorities.
For the inside of the house, no. Arcadia has five neighborhood associations recognized by City Council resolution, each with its own Architectural Review Board, and the resolution says the board does not review work that happens only inside a building without substantially changing how it looks from outside — so attic cable runs, mesh nodes, running the network over existing coax, and moving the equipment out of the entry closet are yours to do. It is the outdoor half that can need review: a conduit trench or hardscape in the front or street-side yard, a detached structure or cabinet for equipment, mechanical equipment such as a generator, ground-mounted solar, or a wall or fence over two feet where a gate opener goes. We will tell you at the estimate which side of that line your job falls on, and draw it up so it can be submitted.
Not from the router, which is the surprising part. When Arcadia police examined the camera found on the 1600 block of Oakwood Avenue in July 2024, they reported it had no internal storage and a mobile hotspot connected to it — a device set up that way is on a cellular connection and never on your Wi-Fi, so it will not appear in your router's client list and there is nothing to block. The check is a physical one: walk the frontage and the property line — hedge, mailbox post, utility pedestal, low wall — and look for anything with a fresh cable tie, a taped seam, or a housing that does not match the boxes the utilities left. If you find something, leave it where it is and call Arcadia PD. The part we help with is the other side of it: getting one camera covering the approach rather than all of them on the door, keeping a recording locally as well as in the cloud so a dropped internet link is not a lost night, and setting an alert for when a camera goes quiet.
